This document specifies a test method for the determination of Fatty Acid Methyl Ester (FAME) content in diesel fuel or domestic heating fuel by mid infrared spectrometry, which applies to FAME contents of the three measurement ranges as follows:

—  range A: for FAME contents ranging from approx. 0,05 % (V/V) to approx. 3 % (V/V);

—  range B: for FAME contents ranging from approx. 3 % (V/V) to approx. 20 % (V/V);

—  range C: for FAME contents ranging from approx. 20 % (V/V) to approx. 50 % (V/V).

Principally, higher FAME contents can also be analysed if diluted; however, no precision data for results outside the specified range is available at present.

This test method was verified to be applicable to samples which contain FAME conforming to EN 14214. Reliable quantitative results are obtained only if the samples do not contain any significant amounts of other interfering components, especially esters and other carbonyl compounds which possess absorption bands in the spectral region used for quantification of FAME. If such interfering components are present, this test method is expected to produce higher values.

This document specifies requirements and test methods for marketed and delivered automotive diesel fuel. It is applicable to automotive diesel fuel for use in diesel engine vehicles designed to run on automotive diesel fuel containing up to 7,0 %(V/V) Fatty Acid Methyl Ester (FAME). NOTE For the purposes of this document, the terms "% (m/m)" and "% (V/V)" are used to represent respectively the mass fraction and the volume fraction.

This document specifies requirements on petrol fuel for use as fuel in small engines, together with the methods to be applied for testing these properties. This document specifies requirements for two types of petrol fuel having low aromatics and sulfur content: - one type for use in four-stroke engines with separate lubrication; and - one mixed petrol fuel type for use in mixture-lubricated engines. Testing the properties of the added engine oil is out of the scope of this document. NOTE For the purposes of this document, the terms “% (m/m)” and “% (V/V)” are used to represent respectively the mass fraction and the volume fraction.
