1 Name of determination

This determination is the Fuel Standard (Ethanol E85) Determination 2012.

2 Commencement

This determination commences on 1 November 2012.

In this determination:

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

CEN/TS followed by a number means the testing method developed under that code and number by the standards development organisation called the European Committee for Standardization.

E85 means a fuel blend consisting of:

(a) 70–85% ethanol; and

(b) petrol that meets the requirements of the Fuel Standard (Petrol) Determination 2001.

EN followed by a number means the testing method developed under that code and number by the standards development organisation called the European Committee for Standardization.

Note 1 Testing method ASTM D4815–09 has been validated for use in the analysis of oxygenates (ethers (5 or more C atoms) and higher alcohols (C3-C8)) in ethanol/unleaded petrol blended fuels containing 70 to 85% ethanol, providing standards are prepared in 80% ethanol blended with unleaded petrol.

Note 2 Testing methods for Motor Octane Number and Research Octane Number in E85 are not yet available. The minimum targets specified in section 4 are interim targets until a testing method is available. These minimum targets allow for engine calibration.

(2) A testing method mentioned in subsection (1) is one that is in force on the day on which this determination commences.
