ASTM D5132机动车乘客车厢内使用的聚合材料的水平燃烧速度的标准试验方法
ASTM D5132 Standard Test Method for Horizontal Burning Rate of Polymeric Materials Used in Occupant Compartments of Motor Vehicles
ASTM D5132机动车乘客车厢内使用的聚合材料的水平燃烧速度的标准试验方法

This test method provides a standard laboratory procedure for measuring and comparing the burning rates of polymeric materials under specified controlled conditions.
The rate of burning is affected by such factors as density, direction of rise, and type and amount of surface treatments. The thickness of the finished specimens must also be taken into account. These factors must be considered in order to compare materials on the same basis.
In this procedure, the specimens are subjected to one or more specific sets of laboratory test conditions. If different test conditions are substituted or the end-use conditions are changed, it is not always possible by or from this test method to predict changes in the fire-test-response characteristics measured. Therefore, the results are valid only for the fire test exposure conditions described in this procedure.
1. Scope
1.1 This test method is intended for use as a small-scale laboratory procedure for comparing the relative horizontal burning rates of polymeric materials used in occupant compartments of motor vehicles.
1.2 Units—The values stated in SI units are to be regarded as standard.
1.3 This test method, Federal Safety Standard MVSS 302, SAE J369, and ISO 3795 address the same subject matter, but differ in technical content.
1.4 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazards or fire risk assessment of materials, products, or assemblies under actual fire conditions.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 7.
1.6 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.
Note 1—This standard and ISO 3795 address the same subject matter, but differ in technical content.
