Petroleum products - Gum content of fuels - Jet evaporation method - Amendment 1: Purity requirement for n-heptane (ISO 6246:2017/Amd 1:2019)

This document specifies a method for determining the existent gum content of aviation fuels and the
gum content of motor gasoline or other volatile distillates. It includes the determination of products
containing ethanol (up to a volume fraction of 85 %) and ether-type oxygenates and deposit control
additives.
For determination of gum content in automotive ethanol (E85) fuel, no precision data is available
(see 14.1).
For non-aviation fuels, a procedure for the determination of the heptane-insoluble portion of the residue
is also described.
CAUTION — This method is not intended for the testing of gasoline components, particularly
those with a high percentage of low-boiling unsaturated compounds, as they can cause
explosions during evaporation.

Ta dokument določa metodo za določevanje obstoječe vsebnosti smolnega ostanka v letalskih gorivih in vsebnosti smolnega ostanka v bencinu za motorna vozila ali drugih hlapnih destilatih. Vključuje določevanje izdelkov, ki vsebujejo etanol (s prostorninskim deležem do vključno 85 %) ter etrske kisikove spojine in aditive za nadzor ostankov.
Za določevanje vsebnosti smolnega ostanka v etanolu (E85), ki se uporablja kot motorno gorivo, ni na voljo podatkov o natančnosti (glej točko 14.1).
Za goriva, ki se ne uporabljajo v letalstvu, je opisan tudi postopek za določevanje dela ostanka, ki ni topen v heptanu.
POZOR – ta metoda ni namenjena za preskušanje komponent bencina, zlasti tistih z visokim deležem nenasičenih spojin z nizkim vreliščem, ker lahko med izhlapevanjem povzročijo eksplozije.

Petroleum products - Determination of low concentration of sulfur in automotive fuels - Energy-dispersive X-ray fluorescence spectrometric method (ISO 13032:2024)
EN ISO 13032:2024

This document is directed specifically at the lower end of the concentration range covered in ISO 20847. By selecting the instrument type, a better signal-to-background ratio for sulfur K L2,3 emission is assured. A knowledge of the general composition of the sample for analysis is advantageous in obtaining the best test result. Compared to the previous version new fuels have been added to the scope. In addition, the precision and bias statements as well as the concentration range were updated based on results of a new interlaboratory study. This has been done for gasoline and diesel type fuels including new fuels HVO and GTL as well as for FAME type samples.

Automotive fuels - Determination of hydrocarbon group types and select hydrocarbon and oxygenate compounds - Gas chromatography with vacuum ultraviolet absorption spectroscopy (GC-VUV) method
EN 18015:2024

This test method is a standard procedure for the determination of saturates, olefins, aromatics and oxygenates in unleaded petrol using gas chromatography and vacuum ultraviolet detection (GC-VUV).
Concentrations of compound classes and certain individual compounds are determined by mass fraction % (m/m) or volume fraction % (V/V). The concentration ranges for which precision has been determined are as given in Table 1.
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, respectively.
The method is found to be applicable to other oxygenates including isopropanol, iso-butanol, tert-butanol, n-propanol, acetone, tert-pentanol and di-isopropyl ether (DIPE), however precision has not been determined.
Table 1 — Ranges of method applicability
Property   Units   Applicable Range
Saturates   % (V/V)   21,48 to 80,87
Olefins   % (V/V)   0,22 to 41,90
Aromatics   % (V/V)   2,35 to 64,55
Benzene   % (V/V)   0,20 to 2,54
Toluene   % (V/V)   0,87 to 30,97
Ethylbenzene   % (V/V)   0,20 to 3,45
Xylenes   % (V/V)   0,49 to 18,59
Methanol   % (V/V)   0,07 to 15,30
Ethanol   % (V/V)   0,08 to 24,96
MTBE   % (V/V)   0,22 to 22,21
ETBE   % (V/V)   0,13 to 23,44
TAME   % (V/V)   0,24 to 21,96
TAEE   % (V/V)   0,24 to 8,60
Oxygen   % (m/m)   0,52 to 12,19
Individual hydrocarbon components are typically not baseline-separated by the procedure described in this test method. The coelutions are resolved at the detector using VUV absorbance spectra and deconvolution algorithms.
While this test method reports by mass fraction % (m/m) or volume fraction % (V/V) for several specific components that can be present in unleaded petrol, it does not attempt to speciate all possible components that can occur in unleaded petrol. In particular, this test method is not intended as a type of detailed hydrocarbon analysis (DHA).
This test method has been tested for unleaded petrol according EN 228 [1]; the method may apply to petrol blending streams but has not been extensively tested for such applications.
WARNING —The use of this document may involve hazardous materials, operations and equipment. This document does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.

Liquid petroleum products - Vapour pressure - Part 1: Determination of air saturated vapour pressure (ASVP) and calculated dry vapour pressure equivalent (DVPE)
EN 13016-1:2024

This European Standard specifies a method for the determination of the air saturated vapour pressure (ASVP) (total vapour pressure), exerted in vacuo, by volatile, low viscosity petroleum products, components, ethanol blends up to 85 % (V/V), and feedstocks containing air. A dry vapour pressure equivalent (DVPE) can be calculated from the air containing vapour pressure (ASVP) measurement.
The conditions used in the test described in this standard are a vapour-to-liquid ratio of 4:1 and a test temperature of 37,8 °C.
The equipment is not wetted with water during the test, and the method described is therefore suitable for testing samples with or without oxygenates; no account is taken of dissolved water in the sample.
This method described is suitable for testing air saturated samples with a DVPE between 15,5 kPa and 106,0 kPa; vapour pressures outside this range can be measured but the precision has not been determined.
This document is applicable to fuels containing oxygenated compounds up to the limits stated in the relevant Council Directive 85/536/EEC [10], and for ethanol-fuel blends up to 85 % (V/V) ethanol.
NOTE   For the purposes of this European Standard, the terms "% (m/m)" and "% (V/V)" are used to represent the mass and volume fractions respectively.
WARNING - The use of this standard can involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of users of this standard to take appropriate measures to ensure the safety and health of personnel prior to application of the standard, and fulfil statutory and regulatory requirements for this purpose.

Liquid petroleum products - Determination of total contamination - Part 1: Middle distillates and diesel fuels
EN 12662-1:2024

This European Standard specifies a method for the determination of the content of undissolved substances, referred to as total contamination, in middle distillates, in diesel fuels containing up to 30 % (V/V) fatty acid methyl esters (FAME), and in neat FAME. The working range is from 12 mg/kg to 30 mg/kg and it was established in an interlaboratory study by applying EN ISO 4259 [2].
This European Standard in general applies to products having a kinematic viscosity not exceeding 8 mm2/s at 20 °C, or 5 mm2/s at 40 °C, e.g. diesel fuel as specified in EN 590 [1].
This test method may be used for diesel fuels containing more than 30 % (V/V) FAME and for petroleum products having a kinematic viscosity exceeding 8 mm2/s at 20 °C, or 5 mm2/s at 40 °C, however in such cases the precision of the test method is not defined.
NOTE 1   Excessive contamination in a fuel system can give rise to premature blocking of filters and/or hardware failure, and is therefore undesirable.
NOTE 2   For the purposes of this European Standard, the term "% (V/V)" is used to represent the volume fraction, φ, of a material.
WARNING - Use of this standard may involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problems associated with its use.

Automotive fuels - Determination of iodine value in fatty acid methyl esters (FAME) - Calculation method from gas chromatographic data
EN 16300:2024

This European Standard specifies a calculation procedure for the determination of Iodine value ("CIV" - "calculated iodine value"), of fatty acid methyl esters (FAME) to be used either as automotive or heating fuel for diesel engines as specified in EN 14214 [2] or as an extender for automotive fuel for diesel engines as specified in EN 590 [4].
This procedure has originally been described in Annex B of EN 14214:2008 [2]. The calculation procedure is now specified for methyl esters between C14 and C24. The calculation procedure uses as data entry the results from the gas chromatography determination (GC) according to EN 14103 of individual fatty acid methyl esters and is based on AOCS recommended practice Cd 1c – 85 for the determination of the iodine value of edible oil from its fatty acid composition. It is important to recognise that the latest version of EN 14103 is to be used for the determination of individual FAME components.
NOTE 1   Experience from the field and from several precision evaluation campaigns in Germany and elsewhere indicates that the results of the determination of iodine value by calculation specified here are very close to results obtained by titration with Wijs solvent according to EN 14111. Observed small differences were always found to be smaller than the reproducibility published in the actual EN 14111.
For informative purposes only, but not for cases of dispute, EN 14331 [5] may also be used to extract the FAME contents from FAME containing diesel fuels (like B5, B7, B30, etc.) and to use the contents of the individual FAME components from this method as data entry for the calculation specified in this European Standard.
In principle, other fatty acid alkyl esters can also be analysed. However, neither the close correlation to the titration method EN 14111 has been verified nor is any precision information available for such an extension of application range.
NOTE 2   For the purposes of this European Standard, the term "% (m/m)" is used to represent the mass fraction, µ, of a material.

Automotive fuels - LPG - Requirements and test methods
EN 589:2024

This document specifies requirements and test methods for marketed and delivered automotive liquefied petroleum gas (LPG), with LPG defined as low pressure liquefied gas composed of one or more light hydrocarbons which are assigned to UN 1011, 1075, 1965, 1969 or 1978 only and which consists mainly of propane, propene, butane, butane isomers, butenes with traces of other hydrocarbon gases.
This standard is applicable to automotive LPG for use in LPG engine vehicles designed to run on automotive LPG.
NOTE   For the purposes of this European Standard, the terms "% (m/m)" and "% (V/V)" are used to represent respectively the mass fraction, µ, and the volume fraction, φ.
WARNING - Attention is drawn to the risk of fire and explosion when handling LPG and to the hazard to health arising through inhalation of excessive amounts of LPG.
LPG is a highly volatile hydrocarbon liquid which is normally stored under pressure. If the pressure is released large volumes of gas will be produced which form flammable mixtures with air over the range of approximately 2 % (V/V) to 10 % (V/V). This European Standard involves the sampling, handling and testing of LPG. Naked flames, unprotected electrical equipment electrostatic hazards etc. are sources of ignition for LPG.
LPG in liquid form can cause cold burns to the skin. The national health and safety regulations apply.
LPG is heavier than air and accumulates in cavities. There is a danger of suffocation when inhaling high concentrations of LPG.
CAUTION - One of the tests described in this European Standard involves the operator inhaling a mixture of air and LPG vapour. Particular attention is drawn to the cautionary statement provided in A.1, where this method is referred to.
