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) supply

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.

CAS no., for a parameter, means the Chemical Abstracts Service Registry number for the parameter.

petrol does not include aviation gasoline (avgas) supplied for use in aircraft.

pool average for aromatic content, means the average amount of aromatics in all batches of petrol across all grades manufactured in Australia, or imported, by a supplier in each 12 months starting on 1 January.

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 %’.
