4 Definitions

Note: A number of expressions used in this instrument are defined in section 4 of the Fuel Quality Standards Act 2000, including fuel.

In this instrument:

ASTM followed by an alphanumeric code means the testing method developed under that code by the standards development organisation called ASTM International.

biodiesel has the same meaning as in the Fuel Quality Standards (Biodiesel) Determination 2025.

conventional diesel has the same meaning as in the Fuel Quality Standards (Conventional Diesel) Determination 2025.

EN followed by a numeric code means the testing method developed under that code by the European Committee for Standardization.

IP followed by a numeric code means the testing method developed under that code by the chartered professional body called the Energy Institute.

mg/kg means milligrams per kilogram and is equivalent to ‘parts per million’ or ‘ppm’ by mass.

% m/m means per cent mass by mass, and is equivalent to ‘mass %’, ‘% mass’ and ‘weight %’.

paraffinic diesel means a fuel that:

(a) consists of a minimum of 95% paraffinic (alkane) hydrocarbons before any blending with biodiesel; and

(b) is suitable for use as a substitute for conventional diesel.

% v/v means per cent volume by volume, and is equivalent to ‘volume %’, ‘vol %’ and ‘% vol’.

5 Fuel standard for paraffinic diesel

(1) In relation to a parameter mentioned in an item of the following table, paraffinic diesel must comply with the specification for that parameter mentioned in that item.

(2) For subsection (1), compliance with the specification for a parameter is determined by using the testing method for that parameter mentioned in that item of the table.
