(1) Unless the contrary intention appears:

(a) words and expressions that are used in the Code have the same meaning in this Instrument; and

(b) words and expressions that are used in the Regulations have the same meaning in this Instrument.

(2) In this Instrument:

CAS Number for an active constituent means the numerical identifier assigned to the constituent by the Chemical Abstracts Service (CAS).

Chemical Name for an active constituent generally means the name assigned to the constituent by the International Union of Pure and Applied Chemistry (IUPAC). Where an IUPAC name is not available, a suitable alternative such as the Chemical Abstracts Name (the systematic name assigned by the Chemical Abstracts Service) will be used instead.

Code means the Agricultural and Veterinary Chemicals Code scheduled to the Agricultural and Veterinary Chemicals Code Act 1994.

Common Name for an active constituent means the name commonly assigned to the constituent, including those common names assigned by the International Organisation for Standardisation (ISO), under the ISO 1750 Standard.

Impurity for an active constituent means a chemical substance other than the active constituent itself (for example a process byproduct) present in a commercially available active constituent.

Maximum Impurity Level for an Impurity, including a Toxicologically Significant Impurity in an active constituent means the maximum permissible amount of the Impurity as a proportion of the total amount of active and impurities, typically in units of g/kg or mg/kg.

Minimum Purity for an active constituent means the minimum permissible amount of active constituent as a proportion of the total amount of active constituent and impurities. Most commonly it is specified in units of g/kg, and when noted, is determined on a dry weight basis (g/kg).

Regulations means the Agricultural and Veterinary Chemicals Code Regulations 1995.

Table means the table in the Schedule to this Instrument.

Technical active constituent (TC) means a commercially available active constituent that has been isolated (as far as practicable) from the starting materials, solvents and catalysts used to produce it as well as from manufacturing byproducts. A TC is traded between manufacturers of active constituents and manufacturers of end use products and is generally formulated before use as a pesticide. A salt or other derivative of the active constituent may be formed during the formulation process.

Technical concentrate (TK), also known as a manufacturing concentrate, may be an active constituent which has not been isolated from the materials used to produce it, or it may be a diluted TC intended for use in preparing formulations. In some cases it is necessary or advantageous to manufacture formulations from a TK rather than a TC. For example, the active constituent may be unstable or more hazardous in a pure form, or an isolation process may introduce unnecessary cost and complexity, especially if the main ingredient removed is water.
