This revised International Standard describes a method for determining bulk density of solid biofuels with the use of a standardized measuring container. This method is applicable to all pourable solid biofuels with a nominal top size of maximum 63 mm. while the maximum particle length is 200 mm. For fuels with a nominal top size larger than 63 mm, a different method is described.

Note: The scope has been changed from the previous version

This document specifies requirements and test methods for marketed and delivered unleaded petrol. It is applicable to unleaded petrol for use in petrol engine vehicles designed to run on unleaded petrol. This document specifies two types of unleaded petrol: - one type with a maximum oxygen content of 3,7 % (m/m) and a maximum ethanol content of 10,0 % (V/V) in Table 1; - one type in Table 2 with a maximum oxygen content of 2,7 % (m/m) and a maximum ethanol content of 5,0 % (V/V) intended for older vehicles that are not warranted to use unleaded petrol defined in Table 1. NOTE 1 The two types are based on European Directive requirements [3], [4] and [10]. NOTE 2 For the purposes of this document, the terms "% (m/m)" and "% (V/V)" are used to represent respectively the mass fraction, µ, and the volume fraction, φ.

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 defines a method for determination the mechanical durability of pellets. The mechanical durability is a measure of the resistance of compressed fuels towards shocks and/or abrasion as a consequence of handling and transportation.
