This instrument is the Fuel Quality Standards (Biodiesel) Determination 2019.

This instrument commences on 1 October 2019.

3 Authority

This instrument is made under section 21 of the Fuel Quality Standards Act 2000.

4 Definitions

Note: A number of expressions used in this instrument are defined in section 4 of the Act, including the following:

(a) fuel

(b) inspector

In this instrument:

Act means the Fuel Quality Standards Act 2000.

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

biodiesel means a diesel fuel obtained by esterification of oil derived from plants or animals.

diesel has the same meaning as in the Fuel Quality Standards (Automotive Diesel) Determination 2019.

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

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

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

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

(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.

Note: The testing methods listed in the table are the methods that will be used by inspectors and other persons authorised to conduct tests on fuel under the Act to determine whether the fuel complies with the relevant fuel standard. Subsection (2) does not prevent other persons (including persons supplying fuel) from using other test methods to ensure that the fuel complies with the relevant fuel standard.
