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 the physical and mechanical properties of pipes made from unplasticized polyamide (PA-U) in accordance with ISO 16486-1, intended to be buried and used for the supply of gaseous fuels. It also specifies the test parameters for the test methods to which it refers. The ISO 16486 series of standards is applicable to PA-U piping systems, the components of which are connected by fusion jointing and/or mechanical jointing. In addition, this document lays down dimensional characteristics and requirements for the marking of pipes. Pipes conforming to this document are jointed typically by using mechanical, electrofusion or butt fusion techniques.

This document specifies the calculation procedure to convert the volume of liquefied petroleum gas (LPG) and liquefied natural gas (LNG) under the conditions at the time of measurement to the equivalent volume of liquid or vapour at the standard condition, i.e. 15 °C and 101,325 kPaA, or to the equivalent mass or energy (calorific content). It applies to the quantities of refrigerated hydrocarbon liquids stored in or transferred to/from tanks and measured under static storage conditions. Calculation of pressurized gases is out of the scope of this document.

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 specifies a procedure to determine the consistency of a metal-saponified lubricating grease by an oscillatory rheometer. This test method is applicable for fresh as well as used lubricating greases where only small quantities of the grease are present and the usually used worked penetration cannot be determined due to the small quantity. The determined calibration is only valid for metal-saponified lubricating greases like lithium, lithium calcium and also lithium- and calcium complex. The method described in this document is applicable for lubricating greases with NLGI grades 00, 0, 1, 2 and 3 in accordance with ISO 6743-99. For greases of other NLGI grades no precision was determined.
