8、69a:1992 ii BSI 03-1999 National foreword This British Standard has been prepared under the direction of the Automobile Standards Policy Committee and is identical with ISO 3795:1989 “Road vehicles, and tractors and machinery for agriculture and forestry Determination of burning behaviour of interio
9、r materials”, published by the international Organization for Standardization (ISO). This revision of this standard supersedes BS AU 169:1978 which is withdrawn. The revision comprises extension of the title and scope to cover tractors and machinery for agriculture and forestry. The technical conten
10、t of the standard remains unaltered. Cross-reference. The Technical Committee has reviewed the provisions of ISO 2768-1:1989, to which normative reference is made in the text, and has decided that they are acceptable for use in conjunction with this standard. A British Standard does not purport to i
11、nclude all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pa
12、ges i and ii, pages 1 to 8, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover. Licensed Copy: London South Bank University, London South Bank Uni

14、es/trucks, estate cars, coaches), and of tractors and machinery for agriculture and forestry, after exposure to a small flame. This method permits testing of materials and parts of the vehicle interior equipment individually or in combination up to a thickness of 13 mm. It is used to judge the unifo
15、rmity of production lots of such materials with respect to their burning behaviour. Because of the many differences between the real world situation (application and orientation within vehicle interior, conditions of use, ignition source, etc.) and the precise test conditions specified in this Inter
16、national Standard, this method cannot be considered as suitable for evaluation of all true in-vehicle burning characteristics. 2 Normative reference The following standard contains provisions which, through reference in this text, constitute provisions of this International Standard. At the time of
17、publication, the edition indicated was valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent edition of the standard indicated below. Members of IEC and ISO maintain regis
18、ters of currently valid International Standards. ISO 2768-1:1989, General tolerances Part 1: Tolerances for linear and angular dimensions without individual tolerance indications. 3 Definitions For the purposes of this International Standard, the following definitions apply. 3.1 burning rate quotien
19、t of the burnt distance measured according to this International Standard and the time taken to burn this distance it is expressed in millimetres per minute 3.2 composite material material composed of several layers of similar or different materials intimately held together at their surfaces by ceme
20、nting, bonding, cladding, welding, etc. when different materials are connected together intermittently (for example, by sewing, high-frequency welding, riveting), then in order to permit the preparation of individual samples in accordance with clause 6, such materials will not be considered as compo
21、site materials 3.3 exposed side side which faces towards the occupant compartment when the material is mounted in the vehicle 4 Principle A sample is held horizontally in a U-shaped holder and is exposed to the action of a defined low-energy flame for 15 s in a combustion chamber, the flame acting o
22、n the free end of the sample. The test determines if and when the flame extinguishes or the time in which the flame passes a measured distance. 5 Apparatus 5.1 Combustion chamber (see Figure 1), preferably of stainless steel and having the dimensions given in Figure 2. The front of the chamber conta
23、ins a flame-resistant observation window, which may cover the front and which can be constructed as an access panel. The bottom of the chamber has vent holes, and the top has a vent slot all around. The combustion chamber is placed on four feet, 10 mm high. The chamber may have a hole at one end for
24、 the introduction of the sample holder containing the sample; in the opposite end, a hole is provided for the gas line. Melted material is caught in a pan (see Figure 3) which is placed on the bottom of the chamber between vent holes without covering any vent hole area. 5.2 Sample holder, consisting
