Trade Practices Act 1974 - Consumer Protection Notice No. 9 of 2004 - Consumer Product Safety Standard: Portable Fire Extinguishers: Aerosol Type

Scope and product definition: The Notice applies to non‑rechargeable stored pressure portable fire extinguishers of the aerosol type. It does not purport to cover rechargeable units, other classes of extinguishers, or extinguishers outside the stored pressure aerosol form; the product class is defined in the opening declaration (first paragraph).

Reference standard and variations: AS/NZS 4353:1995 is adopted as the base standard (first paragraph) but only as varied by the Notice. The 39 enumerated variations amend clause wording, substitute new clauses, delete clauses and remove entire sections and appendices. Those amendments are integral: compliance means meeting AS/NZS 4353:1995 as modified by the Notice, not the unamended standard.

Interlinking with test and rating standards: The Notice replaces or inserts clauses that reference other standards as the source of test methods, rounding rules and classification and rating. Notably, clause 1.3 as substituted lists AS 2706‑1984 for rounding and interpretation of limiting values, AS/NZS 1850:1997 for classification, rating and performance testing, and AS 2278‑1986 for metal aerosol containers (item (2)). Clause 1.5 as substituted directs that classification and rating shall be determined from tests in AS/NZS 1850 (item (4)). Clause 1.6 prescribes the rounding method in AS 2706 for assessing compliance (item (5)). These cross‑references mean key compliance metrics and tests are performed under the procedures and numeric conventions of those referenced standards.

Performance thresholds: The Notice sets minimum performance requirements. Clause 6.1 (substituted) prescribes minimum required ratings, expressed in fire test classifications: either 1A, 5B and E for ABE powder units; or 5B, 1F and E for BE powder units; or 5B and 1F for liquid based extinguishers (item (11)). Clause 7.2 specifies the intermittent discharge test sequence and requires discharge of at least 85 per cent by weight of contents (item (18)). Clause 7.8 establishes a powder compaction test with a detailed protocol and requires at least two of three tested extinguishers to discharge not less than 85 per cent by weight (item (22)). Those thresholds are expressed by weight and are tied to specific test procedures.

Marking and labelling: The Notice imposes mandatory markings. New clause 9.1 requires the container to be marked with identification and operating instructions in accordance with clause 9.4, clearly visible (item (28)). New clause 9.2 lists mandatory text items that every extinguisher must be legibly marked with, including the words “STORED PRESSURE AEROSOL FIRE EXTINGUISHER”, type of charge, mass of contents, precise expiry wording followed by a nominated expiry date, a “ONE USE ONLY - NOT REFILLABLE” statement, fire test rating as specified, safety warnings about puncturing and incineration, corrosion storage advice, and optional upright storage instruction where appropriate (item (29)). New clause 9.3 prescribes minimum letter height of 3 mm and contrast requirements (item (30)). The Notice also amends colour prescriptions by deleting some specific colour approximations (items (31)-(33)), effectively removing those colour‑matching obligations.

Removal of earlier design and accessory obligations: The Notice deletes and amends provisions that previously required support fittings or specified mounting hardware. For example, clause 3.5.1 is amended to remove the sentence “Every extinguisher shall be provided with a support fitting for, at least, static mounting” (item (9)); a similar removal occurs in clause 6.9 (item (16)). Those deletions change the mechanical accessory expectations of the product.

Deleted material and annexes: Sections 8 and 10 and Appendices A and B of the original AS/NZS 4353:1995 are deleted (items (27), (37)-(39)). Several other clauses are wholly deleted (items (3), (6), (7), (8), (10), (14), (15), (17), (20), (21), (24), (25), (26), (34)-(36)). The effect is that specific procedural or optional material in the original standard is removed from the legally binding regime created by this Notice.

Temporal effect: The Notice takes effect from 1 January 2005 (first paragraph). It was issued on 14 December 2004 (signature line).

Directly affected parties: On its face the Notice sets technical, testing and labelling requirements that must be met by the extinguishers themselves (clauses inserted at items (11), (18), (22), (28)-(31)). In practical terms, those requirements will fall on the participants responsible for ensuring products on the Australian market comply with declared consumer product safety standards. That includes manufacturers and their Australian agents or importers who design, certify, label, import and place non‑rechargeable stored pressure aerosol extinguishers on the market, as well as distributors and retailers who sell them. The Notice itself requires marking and performance on the product; meeting those requirements will be an upstream obligation for producers and importers because the product must carry the prescribed markings (new clause 9.2) and achieve the prescribed test outcomes (new clauses 6.1, 7.2, 7.8).

Testing and conformity bodies: Laboratories and test houses that conduct AS/NZS 1850 classification and the specific intermittent discharge and powder compaction tests in clauses 7.2 and 7.8 will be affected. The Notice explicitly ties classification and rating to AS/NZS 1850 (item (4)), and prescribes detailed testing and acceptance criteria in clauses 7.2 and 7.8 (items (18), (22)). Test laboratories will need to follow the procedural details set out by the Notice, including the precise discharge/pause sequence and the compaction/dropping and bonding periods.

Packaging, labelling and print suppliers: The new marking obligations in clause 9.2 (item (29)) require specific text and presentation on the container. Label designers, printers and packagers will need to ensure the labels contain the precise wording and that lettering meets the 3 mm minimum size and contrast requirements in clause 9.3 (item (30)).

Service and disposal providers: The Notice requires particular disposal instructions to appear on the container, namely “DISCARD AFTER USE. DISCHARGE AND DISCARD BEFORE THE USE BY DATE” followed by the nominated expiry date (clause 9.2(d), item (29)), and the warning “DO NOT PUNCTURE OR INCINERATE THIS CAN EVEN WHEN EMPTY. KEEP IN A COOL PLACE” (clause 9.2(g)). Entities that carry out post‑sale disposal, collection or advice on safe handling will have to interpret and follow those directions in custody and instructions to consumers.

Regulators and enforcement bodies: Although the Notice does not itself set out enforcement mechanisms, it is made pursuant to section 65E(1) of the Trade Practices Act 1974 (first paragraph). That legal vehicle places the standard within the statutory consumer safety framework, so Australian enforcement agencies that administer the Trade Practices Act will be the agencies that apply the standard in practice.

End users and purchasers: Consumers, fleet managers, landlords, facility managers and procurement officers who buy aerosol extinguishers will be affected indirectly because the Notice prescribes which products can lawfully be supplied as meeting the consumer product safety standard. The marking requirements are addressed to end users via the instructions and warnings that must be present on the container (clauses 9.1-9.3, item (28)-(31)).

Secondary supply chain: Because the Notice deletes prior requirements for support fittings (items (9), (16)), companies that previously supplied brackets and mounting hardware may see a change in demand depending on market choices prompted by the new standard. Conversely, removal of certain appendices and procedures may shift reliance onto AS/NZS 1850 and other referenced documents (item (2), (4), (5)).

Express duties in the Notice: The Notice sets express product‑level duties that extinguishers must satisfy. These duties are stated as mandatory requirements for the product itself and are implemented by amending AS/NZS 4353:1995. Key duties include:

• Achievement of prescribed ratings. New clause 6.1 requires minimum classifications and ratings depending on the extinguishing agent: (a) ABE powder units must achieve at least 1A, 5B and E; (b) BE powder units must achieve at least 5B, 1F and E; (c) liquid based extinguishers must achieve at least 5B and 1F. Ratings are to be determined in accordance with AS/NZS 1850 (item (11) and item (4)). These are technical thresholds the product must meet.

• Performance testing and minimum discharge. The intermittent discharge test in new clause 7.2 prescribes a discharge/pause sequence (3 s discharge, 10 s pause, 3 s discharge, 10 s pause, then discharge balance) and requires a minimum discharge of 85 per cent by weight of contents (item (18)). The powder compaction test in new clause 7.8 prescribes a dropping regime, storage (“bonding”) at ambient temperature for at least three months, a pre‑discharge storage at 10-25°C for not less than 24 hours, and discharge/weighting procedures; acceptance requires at least two of three tested extinguishers to discharge not less than 85 per cent by weight (item (22)).

• Marking obligations. New clause 9.1 requires containers to be marked with identification and operating instructions in accordance with clause 9.4 and clearly visible (item (28)). New clause 9.2 prescribes mandatory label text (items (29)(a)-(i)), including explicit wording for expiry and discard instructions, and the requirement “ONE USE ONLY - NOT REFILLABLE” (item (29)(e)). New clause 9.3 prescribes minimum letter height of 3 mm and colour contrast (item (30)). Where an extinguisher lacks “E capability” it must be marked with the electrical prohibition sign given in clause 9.4.2 (see clause 6.1 final sentence at item (11)).

Prescriptive numerical and procedural rules: Clause 1.6 (inserted) prescribes that limiting values are to be assessed using the rounding method in AS 2706 (item (5)). That dictates how numerical test results are to be rounded before comparison with specified limiting values.

Rights and deference: The Notice sets technical obligations but does not itself create explicit enforcement rights, appeal rights, or conformity assessment procedures in its text. It assigns normative content to the amended AS/NZS 4353:1995. The rights of manufacturers, importers and suppliers to challenge administrative decisions or to seek approvals are not addressed in the Notice itself; those procedural rights would be found in the Trade Practices Act 1974 and in administrative law, which the Notice references by making the standard under s 65E(1) (first paragraph).

Interdependence with other standards: The obligation to determine classification and rating from AS/NZS 1850 (new clause 1.5, item (4)) means that producers must follow the tests and definitions in that standard. Similarly, rounding and interpretation of limiting values is governed by AS 2706 (new clause 1.6, item (5)). Conformity therefore requires compliance with multiple referenced standards.

Negative duties implied by deletions: The Notice deletes several clauses that previously imposed mechanical obligations, such as support fitting requirements in clauses 3.5.1 and 6.9 (items (9), (16)). Those deletions remove corresponding duties that might otherwise have required support fittings or static mounting provisions.

Obligation to display expiry and disposal instructions: Clause 9.2(d) requires the precise phrase “DISCARD AFTER USE. DISCHARGE AND DISCARD BEFORE THE USE BY DATE” followed by the nominated expiry date, making expiry information and a discard protocol mandatory on every extinguisher (item (29)(d)). That creates a clear labelling duty relating to product life‑cycle and disposal behaviour.

Practical allocation of duties: While the Notice specifies what the extinguishers must do and what markings they must carry, it does not itself assign, for example, record‑keeping or certification obligations to particular persons. In practice, parties placing products on the market typically must ensure these duties are met by design, testing and labelling, but the Notice itself is expressed as product requirements rather than an explicit list of actor duties.

Notice text and statutory vehicle: The Notice is made pursuant to section 65E(1) of the Trade Practices Act 1974 (first paragraph). The Notice itself does not contain any penalty provisions, enforcement mechanisms, or inspection powers. It is an instrument that declares a consumer product safety standard and sets technical requirements; the statutory basis (s 65E(1)) indicates it is made under a broader legislative framework that regulates consumer product safety, but the Notice does not reproduce or summarise any enforcement or sanction regime.

What the Notice does specify about enforcement: The Notice contains no express statements on how compliance will be monitored, how conformity will be certified, what notices or recalls may be issued, or what penalties apply for contravention of the declared standard. The instrument is silent on procedural aspects such as conformity certification, evidence of compliance, record retention, or import documentation.

Implication from statutory origin: Because the Notice is made under the Trade Practices Act 1974, enforcement, penalties and remedies for contravention of the declared standard will be those set out in the Act and in any subsidiary enforcement instruments or administrative practice under the Act. The Notice itself does not describe those mechanisms; therefore anyone seeking enforcement details must consult the Trade Practices Act 1974 and relevant enforcement guidelines or agency practice. The Notice’s silence means it does not, by itself, create an independent penalty regime beyond what follows from its statutory basis.

Practical enforcement considerations (source‑grounded inference): The Notice places mandatory technical requirements on products (marking, tests and ratings), so in practice regulatory authorities are likely to enforce by testing products against the amended AS/NZS 4353:1995 and by inspecting labels for the mandated wording and letter size (clauses 6.1, 7.2, 7.8, 9.1-9.3). Because the Notice removes some clauses and appendices from the base standard, enforcement will concentrate on the surviving and substituted clauses set out in items (1)-(39). However, the Notice does not itself prescribe the administrative process for enforcement, such as how regulators will treat imported goods at border control or what evidentiary documents suppliers must carry.

Uncertainty and implementation risk: The absence of procedural detail in the Notice creates practical uncertainty about compliance evidence and inspection pathways. For example, the Notice requires testing using AS/NZS 1850 for classification and rating (item (4)) and prescribes discharge percentages and detailed compaction testing (items (18), (22)). But the Notice does not set out who certifies those test reports, whether third‑party conformity assessment is required, or whether manufacturers must lodge certificates with a regulator. Those matters will be resolved by the Trade Practices Act framework and enforcement practice outside the text of the Notice.

Statutory basis: The Notice is issued under section 65E(1) of the Trade Practices Act 1974 (first paragraph). The Notice does not reproduce section 65E(1) or other provisions of the Act, but its statutory origin places the declared standard within the Trade Practices Act’s consumer product safety regime. The Notice itself does not set out the scope of enforcement powers, recall procedures, or penalties, which reside in the Trade Practices Act and associated instruments not reproduced here.

Interaction with referenced standards: The Notice explicitly cross‑references and imports test and numerical rules from other Australian standards. New clause 1.3 (item (2)) identifies AS 2706‑1984 on rounding, AS/NZS 1850:1997 on classification, rating and performance testing, and AS 2278‑1986 on metal aerosol containers as documents referred to in the Standard. New clause 1.5 (item (4)) makes AS/NZS 1850 the source for classification and rating. New clause 1.6 (item (5)) prescribes the rounding method in AS 2706 for assessing compliance. Consequently, compliance requires coordination with those standards; obligations under AS/NZS 4353:1995 as modified by this Notice cannot be interpreted in isolation from AS/NZS 1850 and AS 2706 where those clauses explicitly require their application.

Removal of some New Zealand references: The Notice deletes references to NZS 4507 in clauses 6.1.1 and 6.1.2 (items (12), (13)) and deletes NZS colour approximations in clause 9.4.2.1 and 9.4.2.2 (items (31), (32)). The result is a narrowed set of referenced standards, lessening the binding role of some New Zealand specifications that were present in the unamended AS/NZS 4353:1995.

Effect on private contractual regimes: The Notice alters the technical baseline that suppliers must meet when contracting for aerosol extinguishers in Australia. Contracts that specify compliance with AS/NZS 4353:1995 should be read to include the Notice’s variations from 1 January 2005. Parties that rely on the unamended standard or on deleted appendices will find that those clauses no longer form part of the declared safety standard. Whether private contracts incorporate the regulated version by reference will depend on contractual wording, but the Notice establishes the statutory safety baseline that goods supplied in Australia must meet.

Regulatory overlap and conformity: The Notice does not discuss how it interacts with other regulatory regimes such as workplace health and safety law, building codes, or hazard and dangerous goods legislation. Those regimes remain separately applicable. The Notice confines itself to declaring a consumer product safety standard under the Trade Practices Act; any overlapping requirements from other statutes will continue to apply but are not addressed in this instrument.

Imports and border control: The Notice does not specify customs or border regimes, but because it is a declared consumer product safety standard under the Trade Practices Act, imported extinguishers supplied into the Australian market will be expected to comply with the amended AS/NZS 4353:1995. The Notice does not itself prescribe how importers must demonstrate conformity at the border.

Textual origin and dates: The Notice records three key dates. AS/NZS 4353:1995 was published by Standards Australia on 5 December 1995 (first paragraph). The Notice was dated 14 December 2004 and signed by Chris Pearce, Parliamentary Secretary to the Treasurer (final lines). The declared standard becomes effective from 1 January 2005 (first paragraph).

This instrument does not amend a statute directly; it declares an existing Australian/New Zealand standard (AS/NZS 4353:1995) to be the consumer product safety standard for the specified product class, but only as varied by the Notice. The variations themselves constitute the textual amendments to AS/NZS 4353:1995 for the purposes of the Trade Practices Act. The 39 items listed in the Notice are the only textual modifications recorded in the instrument; there are no further amendments or schedules attached to the Notice.

Internal amendments to the base standard effected by the Notice: The Notice replaces clauses 1.3, 1.5 and 6.1 and inserts clause 1.6 and clause 7.8, among other changes (items (2), (4), (5), (11), (22)). It deletes numerous clauses and Sections 8 and 10 and Appendices A and B (items (3), (6)-(8), (10), (14)-(21), (24)-(27), (35)-(39)). It amends specific clauses concerning support fittings and marking, deletes references to NZS 4507 and specific colour approximations and adjusts text that previously mandated certain accessory fittings (items (9), (12)-(13), (16), (31)-(34)). Those textual modifications together create the amended consumer product safety standard that took effect 1 January 2005.

No further amendments recorded in the instrument: The Notice contains no schedule indicating subsequent amendment dates, transitional provisions or grandfathering clauses. It does not refer to or incorporate amended versions of the referenced standards beyond the editions expressly mentioned in the substituted clause 1.3 text (for example AS 2706‑1984 as amended by Amendment 1 of 1 September 1985 and AS 2278‑1986 as amended by amendment 1 of 1 June 1988) (item (2)). The Notice itself stands as the single instrument effecting the amended standard on the stated effective date.

Practical implication for version control: From 1 January 2005, the legally effective consumer product safety standard for the covered aerosol extinguishers is AS/NZS 4353:1995 as varied by this Notice. Any later revisions of AS/NZS 4353 or of the referenced standards are not incorporated by this Notice unless the Notice is itself amended or superseded; the instrument contains no mechanism for automatic incorporation of future standard revisions.

Documentary record in the Notice: The Notice contains no references to litigation, judicial determinations, administrative appeals, or precedents. It names no cases, cites no decisions, and does not record any disputes or adjudications concerning AS/NZS 4353:1995 or the variations it effects.

Consequences of the absence of litigation material: Because the Notice itself contains no litigation history or interpretive guidance from courts or tribunals, practitioners cannot rely on this instrument alone for judicial interpretation of ambiguous terms. The Notice provides textual obligations and prescribed tests but not judicially developed constructions or administrative enforcement examples. Any legal interpretation questions about the effect or application of the substituted clauses will need to be tested in later administrative or judicial proceedings; none are recorded in this instrument.

Practical points for counsel and compliance officers: In the absence of litigation or agency determinations in the instrument, businesses and lawyers must base compliance strategies on the literal text of the Notice and on the contents of the amended AS/NZS 4353:1995 together with the referenced standards (AS/NZS 1850, AS 2706, AS 2278). Administrative practice under the Trade Practices Act will govern enforcement, recall and penalty procedures, but those procedures are not described here. Where interpretation of a clause is contested, courts or relevant tribunals will be the forums to resolve disputes; the Notice itself provides the substantive text that such adjudications would apply.

Monitoring for future case law: Because the Notice may generate enforcement action, product recalls or disputes, parties concerned with high volumes of supply should monitor administrative decisions and litigation arising after the effective date for interpretive guidance on issues such as the meaning of “E capability”, the application of the 85 per cent discharge requirement in disparate test circumstances, and the evidentiary sufficiency of test reports under AS/NZS 1850. The Notice does not itself supply any such guidance.

Precise mandatory wording and presentation: Clause 9.2(d) requires a specific sentence: “DISCARD AFTER USE. DISCHARGE AND DISCARD BEFORE THE USE BY DATE” followed by the nominated expiry date (item (29)(d)). The Notice prescribes not only the requirement to mark an expiry date but the precise wording that must appear. Failure to reproduce the required wording exactly on the container could be treated as non‑compliance with the declared standard.

Labelling format and minimum size: Clause 9.3 mandates that the marking items in 9.2 and the electrical prohibition sign in 9.4.2 must be in letters not less than 3 mm high and of a colour contrasting with the background (item (30)). A supplier who uses smaller type or poor contrast risks non‑compliance even if all the required text appears in some other form elsewhere on the packaging.

“ONE USE ONLY - NOT REFILLABLE” and disposal instruction: Clause 9.2(e) requires the exact statement “ONE USE ONLY - NOT REFILLABLE” (item (29)(e)). Products labelled or described as refillable, or accompanied by aftermarket refill kits, will conflict with that mandatory statement for non‑rechargeable stored pressure aerosol extinguishers.

E capability and electrical prohibition sign: Clause 6.1 requires units without E capability to be marked with the electrical prohibition sign given in clause 9.4.2 (item (11)). The Notice amends clause 9.4.2.1 by deleting a colour approximation and amends 9.4.2.2 by deleting a red colour approximation (items (31), (32)). That deletion removes certain colour‑matching requirements but preserves the requirement to display the sign. Suppliers must check clause 9.4.2 as amended to ensure the sign is present and visibly conformant; the Notice deletes some colour prescriptions but does not delete the sign requirement itself.

Rounding rules matter: Clause 1.6 prescribes the rounding method in AS 2706 for assessing compliance (item (5)). Tests producing numerical results must be rounded to the same number of figures as in the specified limiting value before comparison. Suppliers and test laboratories must apply the rounding rules of AS 2706 to avoid false failures or false passes on marginal numerical comparisons.

Deleted appendices and procedures: The Notice deletes Appendix A and Appendix B entirely (items (38)-(39)) and removes Section 8 and Section 10 (items (27), (37)). If suppliers or test labs previously relied upon procedures or clarifications in those appendices, they no longer form part of the declared standard. Parties must therefore rely on the remaining clauses and the referenced standards (for example AS/NZS 1850) for the applicable procedures.

Powder compaction timing and bonding: The powder compaction test in clause 7.8 includes a bonding period of not less than three months at ambient temperature and a 24 hour stabilisation at 10-25°C before discharge (item (22)). That long bonding period increases lead time for testing and sample preparation and creates logistical and inventory costs for manufacturers and test labs. A failure to observe these storage periods precisely may invalidate a test.

Intermittent discharge sequencing: Clause 7.2 requires a very specific discharge/pause sequence: 3 s discharge, 10 s pause, another 3 s discharge, another 10 s pause, thereafter discharge balance, and at least 85 per cent mass discharge (item (18)). Test houses and manufacturers must programme discharge apparatus and weigh accurately to that timing. Variations in timing, or measuring discharge as volume rather than weight contrary to the clause, would be non‑compliant.

Removal of support fitting requirement: The deletion of the sentence requiring a support fitting for static mounting in clauses 3.5.1 and 6.9 (items (9), (16)) removes an earlier design expectation. Suppliers who assumed the presence of a support fitting as part of the standard may need to reassess product accessory strategies. Conversely, purchasers who expected mounted extinguishers to include a fitting must check the product offering.

Specificity of mass units: Clause 9.2(c) requires the mass of contents to be given in grams or millilitres (item (29)(c)). Using other units or ambiguous measures may fail to meet the marking requirement.

Deleted references to NZ standards: The Notice deletes references to NZS 4507 and some colour approximations (items (12), (13), (31), (32)). Parties relying on New Zealand specifications in contracts or product data must check the amended standard because some cross‑references are removed.

No procedural guidance on conformity evidence: The Notice prescribes what the product must do and how it must be marked but does not specify what documentary evidence constitutes acceptable proof of compliance when dealing with regulators, customs, or purchasers. That omission is a procedural pitfall for suppliers: test reports, lab accreditation and conformity declarations should be prepared proactively because the Notice does not itself define acceptable conformity documentation.

Checklist approach based on the Notice text

1. Confirm scope and product class

   • Verify the product is a non‑rechargeable stored pressure portable fire extinguisher of the aerosol type. The Notice applies only to that product class (first paragraph).

2. Achieve the minimum ratings per clause 6.1

   • For ABE powder units, ensure classification and rating of at least 1A, 5B and E in accordance with AS/NZS 1850 (item (11)).
   • For BE powder units, ensure classification and rating of at least 5B, 1F and E in accordance with AS/NZS 1850 (item (11)).
   • For liquid based extinguishers, ensure classification and rating of at least 5B and 1F in accordance with AS/NZS 1850 (item (11)).
   • Arrange AS/NZS 1850 testing at an accredited laboratory and retain test reports demonstrating the ratings.

3. Apply AS 2706 rounding rules when assessing limiting values

   • Use the rounding method in AS 2706 when comparing observed or calculated values to specified limiting values (new clause 1.6, item (5)). Round the observed value to the same number of figures as the specified limiting value before comparison.

4. Conduct the intermittent discharge test per clause 7.2

   • Program the discharge sequence: 3 s nominal discharge, 10 s nominal pause, 3 s nominal discharge, 10 s nominal pause, then discharge the balance of the contents.
   • Confirm by weight that the extinguisher discharges a minimum of 85 per cent of its contents (item (18)).
   • Record timing, ambient conditions and weights in a test report.

5. Conduct the powder compaction test per clause 7.8

   • Charge at least five extinguishers and drop each one 500 times from a height of 15 ±1 mm at a rate of 1 ±0.02 Hz onto a rigid horizontal steel plate larger than the extinguisher base (clause 7.8.1, item (22)).
   • Store all specimen extinguishers at ambient temperature for not less than three months without disturbance (clause 7.8.2).
   • Prior to discharge, store extinguishers at 10-25°C for not less than 24 hours (clause 7.8.2).
   • Select three extinguishers, weigh them, determine discharge time as 125 per cent of the time for the uncompacted extinguisher, discharge for that time in the normal operating mode without disturbing compacted contents, reweigh, empty residual powder and weigh again, and calculate percentage discharged (clause 7.8.3).
   • Acceptance requires that at least two of the three extinguishers discharge not less than 85 per cent by weight (clause 7.8.4).
   • Maintain full test records and traceability of sample batches.

6. Ensure labelling meets clauses 9.1-9.3

   • Mark each container clearly and visibly with identification and operating instructions in accordance with clause 9.4 (clause 9.1, item (28)).
   • Include every item listed in clause 9.2: the phrase “STORED PRESSURE AEROSOL FIRE EXTINGUISHER” (9.2(a)); type of charge (9.2(b)); mass of contents in grams or millilitres (9.2(c)); the exact discard/expiry wording and nominated expiry date (9.2(d)); “ONE USE ONLY - NOT REFILLABLE” (9.2(e)); fire test rating as specified (9.2(f)); the puncture/incineration warning and cool storage phrase (9.2(g)); corrosion storage advice (9.2(h)); and, where appropriate, “STORE IN UPRIGHT POSITION - DO NOT INVERT” (9.2(i)) (item (29)).
   • Use letters not less than 3 mm high and ensure colour contrast with the background for the listed markings and the electrical prohibition sign if applicable (clause 9.3, item (30)).
   • If the extinguisher lacks E capability, mark it with the electrical prohibition sign in clause 9.4.2 as required by clause 6.1 (item (11)). Note that specific colour approximations in clause 9.4.2 were deleted by the Notice (items (31), (32)), so ensure the sign is visible with appropriate contrast.

7. Verify deleted requirements and optional instructions

   • Do not rely on clauses or appendices that the Notice deleted. For example, Sections 8 and 10 and Appendices A and B are deleted (items (27), (37)-(39)). Confirm that all compliance steps you document rely on the amended standard and the referenced documents AS/NZS 1850 and AS 2706, as required by the Notice (items (2), (4), (5)).

8. Document conformity evidence proactively

   • Because the Notice does not detail procedural conformity assessment, assemble and retain: accredited test reports showing AS/NZS 1850 ratings, test reports for intermittent discharge and powder compaction tests demonstrating ≥85 per cent discharge, lab accreditation records, photos/scans of product labels showing the required wording and letter height, and internal manufacturing records showing traceability of batches tested.
   • Make sure test reports explicitly show the rounding method used consistent with AS 2706 if numerical comparisons are marginal.

9. Review marketing and instructional materials

   • Ensure that user instructions, safety data sheets, product datasheets and sales literature do not contradict the container markings (for example by claiming refillability where the product must be marked “ONE USE ONLY - NOT REFILLABLE”).
   • Update sales, procurement and contract documentation to require compliance with AS/NZS 4353:1995 as varied by Consumer Protection Notice No. 9 of 2004 effective 1 January 2005.

10. Plan lead times and inventory for bonding periods

    • The powder compaction test requires a three month ambient bonding period plus stabilisation; factor these timeframes into prototype testing and batch release plans. Failure to allocate sufficient storage time may delay testing and certification.

11. Seek legal or technical clarification where needed

    • If a supplier or importer has doubt about the interpretation of elements such as “E capability”, the application of deleted appendices, or the sufficiency of test evidence, seek technical clarification from an accredited test laboratory and legal advice referencing the Trade Practices Act and any administrative guidance from the enforcing agency. The Notice itself provides the substantive technical text but not procedural enforcement detail.

Concluding operational note: The Notice prescribes product content, tests and mandatory labelling with specific wording, numeric thresholds and storage/test sequences. Compliance requires aligning product design, production, labelling and testing to the substituted clauses listed in items (1)-(39), and documenting all test evidence and labelling proofs in case of regulatory enquiries under the Trade Practices Act framework.
