This European Standard lays down harmonized identifiers for marketed liquid and gaseous fuels. The requirements in this standard are set to complement information needs of users regarding the fuel- and vehicle-compatibility that are placed on the market. The development of this standard focused on vehicles placed on the market for the first time, which does not preclude the application of this standard also to vehicles already in circulation. The identifier is intended to be visualized at dispensers and refuelling points, on vehicles, in motor vehicle dealerships and in consumer manuals as described in this document.
Marketed fuels include for example petroleum-derived fuels, synthetic fuels, biofuels, natural gas, liquefied petroleum gas, hydrogen and biogas and blends of the aforementioned delivered to non-stationary applications.

This document specifies a procedure for rating the tendencies of gas turbine fuels to deposit decomposition products within the fuel system. It is applicable to middle distillate and wide-cut fuels and is particularly specified for the performance of aviation gas turbine fuels. The test results are indicative of fuel thermal oxidation stability during gas turbine operation and can be used to assess the level of deposits that form when liquid fuel contacts a heated surface at a specified temperature. This method is also applicable to aviation turbine fuel that consists of conventional and synthetic blending components as defined in the scope of for instance ASTM D7566[1] and Def Stan 91-091[2]. NOTE      For the benefit of those using older instruments, non-SI-units and recalculated numbers are given in between brackets where they are more suitable.

This document establishes the rating of diesel fuel oil in terms of an arbitrary scale of cetane numbers
(CNs) using a standard single cylinder, four-stroke cycle, variable compression ratio, indirect injected
diesel engine. The CN provides a measure of the ignition characteristics of diesel fuel oil in compression
ignition engines. The CN is determined at constant speed in a pre-combustion chamber-type
compression ignition test engine. However, the relationship of test engine performance to full scale,
variable speed and variable load engines is not completely understood.
This document is applicable for the entire scale range from 0 CN to 100 CN but typical testing is in the
range of 30 CN to 65 CN. An interlaboratory study executed by CEN in 2013 (10 samples in the range
52,4 CN to 73,8 CN)[3] confirmed that paraffinic diesel from synthesis or hydrotreatment, containing up
to a volume fraction of 7 % fatty acid methyl ester (FAME), can be tested by this test method and that
the precision is comparable to conventional fuels.
This test can be used for unconventional fuels such as synthetics or vegetable oils. However, the
precision for those fuels has not been established and the relationship to the performance of such
materials in full-scale engines is not completely understood.
Samples with fluid properties that interfere with the gravity flow of fuel to the fuel pump or delivery
through the injector nozzle are not suitable for rating by this method.
NOTE This document specifies operating conditions in SI units but engine measurements are specified in
inch-pound units or Fahrenheit because these are the historical units used in the manufacture of the equipment,
and thus some references in this document include these and other non-SI units in parenthesis.

This European Standard specifies requirements and test methods for marketed and delivered automotive LPG (Liquefied Petroleum Gas). It is applicable to automotive LPG for use in LPG engine vehicles designed to run on automotive LPG.
This revision concerns lowering the sulfur limit levels, inclusion of EN 16423 and updating towards revised versions of EN 15470 and EN 15471.
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. All procedures should be conducted away from sources of ignition such as naked flames, unprotected electrical equipment and electrostatic hazards. Testing should be performed as far as practicable under an electrically-safe ventilation hood.
LPG in liquid form can cause cold burns to the skin. Protective clothing such as gloves and goggles should be worn if contact with the skin is likely to occur.
Unnecessary inhalation of LPG vapour should be avoided. The operator should not be exposed to atmospheres containing more than 1 800 mg/m3 over an 8 h time-weighted average (TWA) reference period, or more than 2 250 mg/m3 over a short term, 10 min reference period. 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.

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.

This document specifies a test method using the high-frequency reciprocating rig (HFRR), for assessing the lubricating property of diesel fuels, including those fuels which could contain a lubricity-enhancing additive. It defines two methods for measurement of the wear scar; Method "A" — Digital camera, and Method "B" — Visual observation.
This test method applies to fuels used in diesel engines.
NOTE It is not known if this test method will predict the performance of all additive/fuel combinations, including paraffinic fuels for which no additional correlation testing has been performed. Nevertheless, no data has been presented to suggest that such fuels are not within scope.

This document specifies a procedure for the calculation of the cetane index of middle-distillate fuels
from petroleum-derived sources. The calculated value is termed the “cetane index by four-variable
equation”. Throughout the remaining text of this document, the term “cetane index” implies cetane
index by four-variable equation.
This document is applicable to fuels containing non-petroleum derivatives from tar sand and oil
shale. It is not applicable to pure hydrocarbons, nor to distillate fuels derived from coal. Cetane index
calculations do not take into account the effects from additives used to enhance the Cetane number.
NOTE 1 This document was originally developed using a matrix of fuels, some of which contain non-petroleum
derivatives from tar sands and oil shale.
NOTE 2 The cetane index is not an alternative way to express the cetane number; it is a supplementary tool, to
be used with due regard for its limitations.
NOTE 3 The cetane index is used to estimate the cetane number of diesel fuel when a test engine is not
available to determine this property directly, or when insufficient sample is available for an engine rating.
The most suitable range of fuel properties for application of this document is as follows:
Fuel property Range
Cetane number 32,5 to 56,5
Density at 15 °C, kg/m3 805,0 to 895,0
10 % (V/V) distillation recovery temperature, °C 171 to 259
50 % (V/V) distillation recovery temperature, °C 212 to 308
90 % (V/V) distillation recovery temperature, °C 251 to 363
Within the range of cetane number (32,5 to 56,5), the expected error of the prediction via the cetane
index equation will be less than ±2 cetane numbers for 65 % of the distillate fuels examined. Errors can
be greater for fuels whose properties fall outside this range of application.
As a consequence of sample-specific biases observed, the expected error can be greater even when
the fuel’s properties fall inside the recommended range of application. Therefore, users can assess the
required degree of prediction agreement to determine the fitness-for-use of the prediction.
NOTE 4 Sample specific biases were observed for distillate fuels containing FAME (fatty acid methyl ester).

This European Standard specifies a test method for the quantitative determination of the indicated cetane number (ICN) of middle distillate fuels and blending components, intended for use in compression ignition engines. The test method utilizes a constant volume combustion chamber with direct fuel injection into heated compressed air. Calibration of the apparatus using blends of primary reference materials over a scale of 0 to 100 enables fuel ignition delays, measured from the resulting pressure increase, to be used to determine and report ICN results.
This European Standard is applicable to middle distillate fuels of both petroleum and non-petroleum origin, hydrocarbon oils, oil-sands based fuels, blending components, fatty acid methyl esters (FAME), blends of fuel containing biodiesel material, diesel fuel oils containing cetane number improver additives, low-sulfur diesel fuel oils, aviation turbine fuels and polyoxymethylene dimethyl ether (OME). However, users applying this standard especially to unconventional distillate fuels are warned that the relationship between cetane number and combustion behaviour in real engines is not yet fully understood.
This European Standard covers the calibrated range of 35 ICN to 85 ICN.
NOTE 1   The analyser can measure ICN outside the calibrated range, but precision has not been determined.
NOTE 2   For the purpose of this standard, the expression "% (V/V)" is used to represent the volume fraction.
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.
