This document specifies a test method for the determination of cetane numbers ("CN") of diesel fuels, using a standard single cylinder, four-stroke cycle, indirect injection engine. The cetane number provides a measure of the ignition characteristics of diesel fuels in compression ignition engines. The cetane number is determined at constant speed in a compression ignition test engine equipped with a swirl chamber.
The cetane number scale covers the range from 0 to 100, but typical testing is performed in the CN range from about 40 to about 75. The precision of this test method covers the CN range from 44 to about 66.
This document is applicable to distillate as well as paraffinic diesel fuels intended for use in diesel engines, including those containing up to a volume fraction of 10 % fatty-acid methyl esters (FAME), ignition-improvers or other diesel fuel additives.
When this engine test procedure is used for other fuels such as synthetics and vegetable oils, samples with fuel properties that interfere with the gravity-based pre-supply pressure to the fuel pump e.g. due to high viscosity can only be used to a limited extent. Precision data for such fuels are not available at this stage.
NOTE The test method is also suitable for determining cetane numbers outside the range of the scope; however, the precision statement only applies for fuels in the specified range.
WARNING - The use of this document can 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 document to take appropriate measures to ensure the safety and health of personnel prior to application of the document, and fulfil statutory and regulatory requirements for this purpose.

This document describes the procedure and rules for extended application of results of tests carried out according to the test methods described in EN 50399, EN 60332 1 2 and EN 61034 2.
The EXAP rules described apply to EN 50399 test results used for classification according to EN 13501 6 in classes B2ca, Cca and Dca, additional smoke production classes s1, s2 and s3 and flaming droplets/particles, to EN 60332 1 2 test results used for classification in classes B2ca, Cca, Dca and Eca and to EN 61034 2 test results used for classification in classes s1a and s1b.
No EXAP procedure and rules have been developed in respect to the results of tests carried out according to the test method described in EN 60754 2. As the parameters (pH and conductivity) for each cable in a family are determined based upon calculation using material test results, this is considered as a matter of direct application. Material test results taken from any one sample of finished cable from a family are sufficient to calculate the parameters for each cable in the family.
Cables with a diameter of 5,0 mm or less are expected to be tested as bundles according to EN 50399. Cables with a diameter of less than or equal to 5,0 mm are included in the specific and general EXAP rules for single core unsheathed power cables only. The rules apply to circular and non-circular cables provided that they fall within the scope of the relevant test method.
A specific EXAP rule has been developed for any of the types of electric cable families as defined in this document. A general EXAP rule has been developed for all electric cable families unless otherwise stated elsewhere in this document.
NOTE 1 Multicore power cables are sometimes referred to as control cables with a rated voltage but for the purposes of this document are considered as power cables. For multipair, multitriple and multiquad control cables, either the general EXAP rule or the specific EXAP rule for power cables or the specific EXAP rule for communication cables can be applied.
The use of the specific EXAP rule gives benefit in the lower number of cables to be tested for a range of cable constructions (product family).
An EXAP is only possible when cables belong to a family as defined in this document.
NOTE 2 For the purposes of this document, the term "electric cables" also covers optical fibre cables.

This document specifies requirements for, and constructions and dimensions of, multicore and multipair cables rated voltage U0/U: 300/500 V, of the following types: - unscreened, sheathed for either exposed or protected wiring (0,5 mm2 to 2,5 mm2, number of cores from 2 to 48); - screened, sheathed for either exposed or protected wiring (0,5 mm2 to 2,5 mm2, number of cores from 2 to 8); - unscreened, sheathed for either exposed or protected wiring (0,5 mm2 to 1,5 mm2, number of screened pairs of cores from 2 to 7). - screened, sheathed for either exposed or protected wiring (0,5 mm2 to 1,5 mm2, number of unscreened pairs of cores from 2 to 7). All cables have stranded tinned copper conductors, halogen-free, thin wall thickness insulation and standard wall thickness sheath. Cable types are specified for use in exposed situations (Class E), and for protected situations (Class P). They are for use in railway rolling stock as fixed wiring or wiring where limited flexing in operation is encountered. These cables are rated for occasional thermal stresses causing ageing equivalent to continuous operational life at a temperature of 90 °C. For standard cables this is determined by the acceptance test defined in EN 50305, using accelerated long-term (5 000 h) thermal ageing indicating a 110 °C/20 000 h temperature index. If the customer were to require lifetime predictions this would be demonstrated based on the temperature index of the product as supplied by the manufacturer. The maximum temperature for short circuit conditions is 160 °C based on duration of 5 s. Under fire conditions the cables exhibit special performance characteristics in respect of maximum permissible flame propagation (flame spread) and maximum permissible emission of smoke and toxic gases. These requirements are specified to permit the cables to satisfy Hazard Level 3 of EN 45545 1 and EN 45545 2. EN 50306 4:2020 is expected to be used in conjunction with EN 50306-1:2020, General requirements, EN 50306-2:2020, Single core cables, and EN 50306-3:2020, Single core and multicore cables.

EN 50306-1 specifies the general requirements applicable to the cables given in EN 50306-2, EN 50306-3 and EN 50306-4. It includes the detailed requirements for S2 sheathing materials and other components called up in the separate parts. NOTE Detailed requirements for insulation systems are given in EN 50306-2. In particular, EN 50306-1 specifies those requirements relating to fire safety which enable the cables to satisfy Hazard Level 3 of EN 45545-1 and EN 45545-2. These cables are rated for occasional thermal stresses which causes ageing equivalent to continuous operational life at a temperature of 105 °C or 90 °C. For standard cables, this is determined by the acceptance test defined in EN 50305, using accelerated long-term (5 000 h) thermal ageing indicating a 125 °C or 110 °C /20 000 h temperature index. If the customer were to require lifetime predictions, this would be demonstrated based on the temperature index of the product as supplied by the manufacturer. The maximum temperature for short circuit conditions is 160 °C based on duration of 5 s. EN 50306-1 is expected to be used in conjunction with one or more of the other parts of EN 50306.

This document describes the procedure and rules for extended application of results of tests carried out according to the test methods described in EN 50399, EN 60332 1 2 and EN 61034 2. The EXAP rules described apply to EN 50399 test results used for classification according to EN 13501 6 in classes B2ca, Cca and Dca, additional smoke production classes s1, s2 and s3 and flaming droplets/particles, to EN 60332 1 2 test results used for classification in classes B2ca, Cca, Dca and Eca and to EN 61034 2 test results used for classification in classes s1a and s1b. No EXAP procedure and rules have been developed in respect to the results of tests carried out according to the test method described in EN 60754 2. As the parameters (pH and conductivity) for each cable in a family are determined based upon calculation using material test results, this is considered as a matter of direct application. Material test results taken from any one sample of finished cable from a family are sufficient to calculate the parameters for each cable in the family. Cables with a diameter of 5,0 mm or less are expected to be tested as bundles according to EN 50399. Cables with a diameter of less than or equal to 5,0 mm are included in the specific and general EXAP rules for single core unsheathed power cables only. The rules apply to circular and non-circular cables provided that they fall within the scope of the relevant test method. A specific EXAP rule has been developed for any of the types of electric cable families as defined in this document. A general EXAP rule has been developed for all electric cable families unless otherwise stated elsewhere in this document. NOTE 1 Multicore power cables are sometimes referred to as control cables with a rated voltage but for the purposes of this document are considered as power cables. For multipair, multitriple and multiquad control cables, either the general EXAP rule or the specific EXAP rule for power cables or the specific EXAP rule for communication cables can be applied. The use of the specific EXAP rule gives benefit in the lower number of cables to be tested for a range of cable constructions (product family). An EXAP is only possible when cables belong to a family as defined in this document. NOTE 2 For the purposes of this document, the term "electric cables" also covers optical fibre cables.

This document specifies fire type-testing requirements and a fire type-test method for soft- and metal-seated isolation valves with one or more obturators. It is not applicable to the testing requirements for valve actuators other than manually operated gearboxes or similar mechanisms when these form part of the normal valve assembly. Other types of valve actuators (e.g. electrical, pneumatic or hydraulic) can need special protection to operate in the environment considered in this valve test, and the fire testing of such actuators is outside the scope of this document.
This document specifies the measurement and assessment criteria for:
a) through-seat leakage;
b) external leakage;
c) cavity overpressure relief of double-seated valves;
d) operability.
This document specifies the rules whereby the fire-type testing qualification for a valve can be extended to untested sizes, pressure ratings and materials of construction of the same basic design type.
Fire test reports of valves tested according to previous editions of this document are acceptable when submitted together with the full and compliant fire test report as per 6.7 of the edition under which it was tested. Any data missing as required from 6.7 within the fire test report are accepted or rejected at the purchaser’s discretion.
NOTE For the purposes of this document, the terms “fire type-test” and “fire test” are synonymous.

This document specifies a test method for testing the capability of a cigarette, positioned on one of three standard substrates, to extinguish or to generate sufficient heat to continue burning, and thus potentially cause ignition of bedding or upholstered furniture. This document is only applicable to factory-made cigarettes that burn along the length of a tobacco column.
This is a performance-based document; it does not prescribe any design features of the cigarette that can lead to improved or degraded performance in the test method. The output of this method has been correlated with the potential for cigarettes to ignite upholstered furniture.

This document specifies the apparatus and methods of test for the assessment of vertical flame spread, heat release, smoke production and occurrence of flaming droplets/particles of vertically mounted electric cables under defined conditions.
NOTE For the purpose of this document, the term “electric cable” covers all power, control and communication cables, including optical fibre cables and hybrid cables used for the conveyance of energy and/or signals.
This document details the apparatus for the fire propagation testing and the arrangement and calibration of the instrumentation to be installed to measure the heat release and the smoke production during the test. The combustion gases are collected in a hood above the test chamber and conveyed through an exhaust system, which allows the measurement of heat release rate and smoke production. Test procedures to be used for type approval testing for classification of cables in classes [2, 7] B1ca, B2ca, Cca and Dca are given. Cable installation on the test ladder and the volume of air passing through the chamber are in accordance with the Commission Decision 2006/751/EC [6], which is reflected in the requirements of this document.
