If a product covered by this instrument has an automatic dispenser, the following procedures are to be incorporated when testing the product:\n\n the procedure in section 7 of AS/NZS 4865.1:2008;\n the procedure in sections 4.7-4.9 of ISO 6369:2023;\n the procedure in sections 6 and 7 of ANSI/ASHRAE 29–2009; and\n the procedure in sections 6 and 7 of ANSI/ASHRAE 29–2015.\n\n1. If an automatic commercial ice-maker with an automatic dispenser is not able to continuously produce and dispense ice because of certain mechanisms within the automatic commercial ice-maker that prohibit the continuous production and dispensing of ice throughout testing, those mechanisms must be overridden to the minimum extent which allows for the continuous production and dispensing of ice when testing the product.\n2. An automatic commercial ice-maker with an automatic dispenser is to have an empty internal storage bin at the beginning of the test period with capacity samples collected according to the requirements of the standard, with the following changes:\n\n samples are to be collected through continuous use of the dispenser rather than in the internal storage bin; and\n the intercepted ice samples are to be obtained from a container in an external ice bin that is filled one-half full of ice and is connected to the outlet of the ice dispenser through the minimal length of conduit that can be used.\n\n## Part 4—GEMS labelling requirements\n\n#### 17 Purpose of this Part\n\nFor the purposes of paragraph 24(1)(b) of the Act, this Part specifies GEMS labelling requirements in accordance with section 26 of the Act for the product classes covered by this instrument.\n\n#### 18 GEMS registration number\n\n1.

It does not apply to domestic ice‑makers (section 10). \n- Defines which machines are covered (automatic commercial ice‑makers up to 1,000 kg/day and with water/drain connections) and creates 12 numbered product classes by configuration, cooling and production mode (definitions and Schedule 1). \n- Requires that the machine's tested energy consumption (from an approved laboratory test) is at or below a calculated maximum energy consumption rate for its product class and tested capacity (the GEMS level requirement) (section 12). The maximum is calculated by an explicit formula using class‑specific constants and variables listed in Schedule 2 (section 13 and Schedule 2). \n- Prescribes which test standards may be used and how tests must be carried out, including special testing rules for ice‑makers with automatic dispensers and when manufacturers must override mechanisms to enable continuous dispensing during tests (sections 14–16). Some approved standards apply only to particular product classes or only if tests are conducted at 230 V / 50 Hz (section 15). \n- Requires registered products to display the current GEMS registration number in advertising, displays and on the product at supply (labelling rules) (section 18). \n- Adds registration and declaration rules: declared energy, capacity and (if declared) potable and condenser water use rates must not understate tested values (section 19). \n- Applies from the date set in the commencement table (the whole instrument commences 12 months after registration) (commencement clause 2).\n\nWho is affected and who acts\n\n- Who pays / bears cost: manufacturers, importers and registrants. They must have products tested to an approved standard, declare test results in their GEMS registration, and affix/display the GEMS registration number (sections 14–19). They may also need to purchase standards documents that are copyright‑protected (Preliminary/COPYRIGHT notes). \n- Who decides: the instrument fixes rules (constants, variables, test methods). Accredited test laboratories perform the tests under the listed standards; the regulator enforces the Act and the instrument (authority is section 23 of the Act; this instrument is made under that authority — section 3). Registrants declare values at registration and are responsible for accuracy (section 19). \n- What behaviour changes: product design or selection will be driven toward meeting the class‑specific energy ceiling (manufacturers may redesign, change components or move product offerings between classes); importers may stop supplying models that cannot meet the calculated maximum; retailers must display registration numbers.\n\nWhy it matters (policy effect and practical trade‑offs)\n\n- Primary mechanism: a numeric performance ceiling per class/capacity that ties market access to tested energy use (sections 12–13 and Schedule 2). That directly influences manufacturer design and product availability. \n- Compliance costs: testing (per sample), potential retesting after design changes, and buying copyrighted standards (instrument incorporates AS/NZS, ISO, ANSI/ASHRAE and AHRI standards — see the COPYRIGHT notes and definitions). Small producers may face proportionally higher compliance costs. \n- Information & monitoring: labelling and registration number rules (section 18) make it easier for regulators and buyers to verify that a product is registered, but they rely on accurate declarations (section 19) and quality of test reports. \n- Technical complexity / implementation risk: the instrument cross‑references several external standards (section 15) and requires unit conversions where standards use imperial units (definitions). Tests for automatic dispensers require specific procedural changes and sometimes overriding machine controls (section 16), which may be technically difficult and require test‑house judgement. \n- Market effects: manufacturers who can meet limits gain access and may earn a modest competitive advantage; models that can't comply will be withdrawn or redesigned. This concentrates benefits for efficient producers and imposes diffuse costs across manufacturers and possibly end‑users via higher prices. \n- Enforcement & discretion: interpretation order is explicit (Act > instrument > AS/NZS 4865.1:2008 > other referenced standards) which reduces some ambiguity but still leaves practical judgments about test implementation to testers and the regulator (section 5). \n\nConcrete references to the instrument\n\n- Scope and exclusions: commercial vs domestic definition and exclusions (section 4; section 10). \n- GEMS level requirement and calculation: tested energy <= maximum energy consumption rate; formula and lookup table in Schedule 2 (sections 12–13; Schedule 2). \n- Approved test standards and conditional use (section 15). \n- Special testing modifications for automatic dispensers and how to collect samples (section 16). \n- Labelling / display of GEMS registration number (section 18). \n- Declaration rules (declared >= tested for energy/water; declared capacity <= tested capacity) (section 19).\n\nPractical implementation points to watch\n\n- Registrants must ensure unit conversions and include condensing unit energy for split systems (definitions). \n- Third‑party copyrights: full standards are not included; the instrument incorporates them by reference, so businesses will likely have to purchase copies to follow test procedures (COPYRIGHT notes). \n- The family‑of‑models rule (section 6) allows multiple models to rely on a single test report if they share test results and characteristics — this reduces per‑model testing cost but creates an incentive to group models strategically. \n\nBottom line: The Determination sets numerical energy ceilings by detailed class and capacity bands and prescribes how to test and label commercial ice‑makers so only products meeting those ceilings can be sold. Compliance requires accredited testing, careful declarations at registration and adherence to specified labelling rules; this shifts costs and technical requirements onto manufacturers/importers and their test laboratories (sections 12–19, Schedule 1, Schedule 2)."}},"importantCases":[],"_links":{"self":"/api/acts/greenhouse-and-energy-minimum-standards-commercial-ice-makers-determination-2025","history":"/api/acts/greenhouse-and-energy-minimum-standards-commercial-ice-makers-determination-2025/history","analysis":"/api/acts/greenhouse-and-energy-minimum-standards-commercial-ice-makers-determination-2025/analysis","conflicts":"/api/acts/greenhouse-and-energy-minimum-standards-commercial-ice-makers-determination-2025/conflicts","importantCases":"/api/acts/greenhouse-and-energy-minimum-standards-commercial-ice-makers-determination-2025/important-cases","documents":"/api/acts/greenhouse-and-energy-minimum-standards-commercial-ice-makers-determination-2025/documents"}}
