1.1本试验方法确定了给定尘云在暴露于炉内局部大气压力下加热的空气时自燃的最低温度。 1.2从本试验方法获得的数据提供了尘云自燃温度的相对测量值。 1.3本试验方法应用于测量和描述材料、产品或组件在受控实验室条件下对热和火焰的响应特性，不应用于描述或评估材料、产品或组件在实际火灾条件下的火灾危险或火灾风险。然而，本试验方法的结果可作为火灾风险评估的要素，该评估考虑了与特定最终用途火灾危险评估相关的所有因素。 1.4本标准无意解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。

1.1 This test method determines the minimum temperature at which a given dust cloud will autoignite when exposed to air heated in a furnace at local atmospheric pressure. 1.2 Data obtained from this test method provide a relative measure of dust cloud autoignition temperatures. 1.3 This test method should be used to measure and describe the properties of materials, products, or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. However, results of this test method may be used as elements of a fire risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use. 1.4 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.
