EN 13238：建筑产品防火测试-基材选择的调理方法和通则 EN 13238：Reaction to Fire Tests for Building Products - Conditioning Procedures and General Rules for Selection of
Substrates Abstract 摘要 The Construction Products Directive requires products to be tested in their end use condition which, for the purpose of substrates, could lead to an economically unrealistic large variety of tests to be carried out. This large spectrum has been reduced to a practical number of standard substrates that enables the majority of end use conditions to be represented. Rules for the selection of such substrates are also given in this standard. BS EN 13238 is for use in conjunction with European Standards covering the reaction to fire test methods for the relevant construction products.
BS EN 13238 describes the conditioning procedures for test specimens which will be tested according to the European standards for reaction to fire.
BS EN 13238 also covers the rules for the selection of substrates for construction products when carrying out reaction to fire tests.
BS EN 13238 does not contain requirements for:
The pre-drying of test specimens for the non-combustibility test according EN ISO 1182
Methods of cleaning (e.g. washing) and other methods for the assessment of durability aspects, which are dealt with in the relevant product standards.

Products are considered in relation to their end use application.
This document applies to three categories, which are treated separately in this European Standard: －construction products, excluding floorings and linear pipe thermal insulation products; floorings, linear pipe thermal insulation products.
EN 13823：建筑产品的对火测试反应- 单体测试 EN 13823：Reaction to Fire Tests for Building Products - Bulding Products Excluding Floorings Exposed to the Thermal Attack by a Single Burning Item Abstract 摘要 The Single Burning Item test can be considered as the backbone of the Euroclass system for building products. The test results are required for a classification D - B (combined with test results from EN 11925-2), for a classification A2 (combined with test results from EN ISO 1716), and sometimes for a classification A1.
TEST PRINCIPLE The specimen is exposed to a diffusive flame of 30 kW. Combustion gases are collected by an exhaust hood for analysis. This gas analysis makes it possible by oxygen depletion to calculate heat release rate from the specimen. Smoke production is assessed by
measuring attenuation of a light beam by smoke in the exhaust duct. The burning behaviour of the specimen is observed for flame spread, and the occurrence of burning particles and droplets.

EN 50266 specifies methods of test for the assessment of vertical flame spread of vertically-mounted bunched wires or cables, electrical or optical, under defined conditions.
The test is intended for type approval testing. The requirements for the selection of cables for testing are given in annex A. The flame spread is measured as the extent of damage of the cable sample. This procedure may be used to demonstrate the cable’s ability to limit flame spread.
This Part 2-4 covers Category C and relates to cables installed on the test ladder to achieve a nominal total volume of non-metallic material of 1,5 litres per metre of test sample. The flame application time is 20 min. The method of mounting uses the front of the standard ladder. The category is intended for general use where low volumes of non-metallic material are required to be evaluated.
A recommended performance requirement is given in annex B.
EN 50268：在燃烧条件下电缆通用测试方法－在规定条件下电缆燃烧烟密度测量 EN 50268：Common Test Methods for Cables under Fire Conditions - Measurement of Smoke Density of Cables Burning under Defined Conditions
Abstract 摘要 The test is performed inside a chamber measuring 3 metres by 3 metres by 3 metres and the test is sometimes referred to as the three metre cube test. The number of lengths and the mounting arrangement of the cables is dependant upon its outer diameter. Once the specimens have been bundled as required, they are placed onto the specimen stand and an alcohol fuel source is placed below the test specimen. At the start of the test the fuel is ignited.
The test is performed by monitoring the transmittance reduction of a white light beam, running from one side of the chamber to the other at a set height, thus monitoring the build up of smoke inside the chamber. A small fan is utilised inside the chamber to prevent the smoke building up in a layered effect and a draft screen is utilised to protect the specimen and the flame source from any wind turbulence.
The test duration is 40 minutes.
Test Results The minimum percentage light transmission is often used to determine if the product has passed or failed the test, often a minimum light transmittance of ≥ 60% is applied in order to classify a cable as low smoke (though this does depend upon the specification document).
Sometimes the limits supplied in specification documents are Ao values. The Ao results are generally calculated by use of the following equation (in accordance with the BeerLambert law), converting the transmittance of light received by the detector into the measured optical density of the smoke (Am):
Am = log10 (I0/It) Where:
I0 is the initial luminous intensity It is the transmitted luminous intensity Ao is calculated by the following equation: Ao = (Am x V) / (K x l) Am is the optical density measured in the cube. V is the volume of the cube in metres. l is the length of the optical path between the windows in metres. K is the number of units of material constituting a test specimen. NB. The value of K is the number of lengths of cable used in the test specimen.

EN 60695-11-10：Fire hazard testing-Part 11-10: Test flames 50 W horizontal and vertical flame test methods Abstract 摘要
Horizontal Testing (HB) - Method A Procedure: A specimen is supported in a horizontal position and is tilted at 45° A flame is . applied to the end of the specimen for 30 seconds or until the flame reaches the 1 inch mark. If the specimen continues to burn after the removal of the flame, the time for the specimen to burn between the 1 and 4 inch marks are recorded. If the specimen stops burning before the flame spreads to the 4 inch mark, the time of combustion and damaged length between the two marks is recorded. Three specimens are tested for each thickness. Horizontal Requirements Rating Specimens must not have a burning rate greater than 1.5 inches/minute for thicknesses between 0.120 and 0.500 inches and 3 HB inches/minute for thicknesses less than 0.120 inches. Specimens must stop burning before the flame reaches the 4 inch mark.
Vertical Testing (V-0, V-1, V-2) - Method B Procedure: A specimen is supported in a vertical position and a flame is applied to the bottom of the specimen. The flame is applied for ten seconds and then removed until flaming stops at which time the flame is reapplied for another ten seconds and then removed. Two sets of five specimens are tested. The two sets are conditioned under different conditions. Vertical Requirements Ratings V-0 Specimens must not burn with flaming combustion for more than 10 seconds
after either test flame application. Total flaming combustion time must not exceed 50 seconds for each set of 5 specimens. Specimens must not burn with flaming or glowing combustion up to the specimen holding clamp. Specimens must not drip flaming particles that ignite the cotton. No specimen can have glowing combustion remain for longer than 30 seconds after removal of the test flame. Specimens must not burn with flaming combustion for more than 30 seconds after either test flame application. Total flaming combustion time must not exceed 250 seconds for each set of 5 specimens. V-1 Specimens must not burn with flaming or glowing combustion up to the specimen holding clamp. Specimens must not drip flaming particles that ignite the cotton. No specimen can have glowing combustion remain for longer than 60 seconds after removal of the test flame. Specimens must not burn with flaming combustion for more than 30 seconds after either test flame application. Total flaming combustion time must not exceed 250 seconds for each set of 5 specimens. V-2 Specimens must not burn with flaming or glowing combustion up to the specimen holding clamp. Specimens can drip flaming particles that ignite the cotton. No specimen can have glowing combustion remain for longer than 60 seconds after removal of the test flame.
EN 60695-11-20：防火测试－第 11-20 部分：500W 火焰测试方法 EN 60695-11-20：Fire Hazard Testing - Part 11-20: Test Flames - 500 W Flame Test Methods Abstract 摘要 Specifies a small-scale laboratory screening procedure for comparing the relative burning behaviour of specimens made from plastics and other non-metallic materials, as well as their resistance to burn-through when exposed to a flame ignition source of 500 W nominal power. This method is applicable to both solid materials and cellular plastic materials having an apparent density of 250 kg/m3 or greater when determined in accordance with ISO 845. It does not apply to thin materials that shrink away from the applied flame without igniting, for which ISO 9773 should be used. The test method described is intended to characterize material performance, for example for quality-control purposes, and is not intended to assess the behaviour to fire of building materials or furnishings. It may be used for the pre-selection of a material, provided that positive results are obtained at a thickness which equals the smallest thickness used in the application. The results obtained provide some information about the behaviour of plastic materials in service, but can never by themselves assure safe performance in service. This test method provides a classification system which may be used for quality assurance or the pre-selection of component materials of products.
