1.1 本规范涵盖了用作塑料材料小规模燃烧试验点火源的实验室燃烧器的物理尺寸和特性。燃烧器与甲烷、丙烷或丁烷供应气体一起使用，火焰高度为20至125 mm。 1.2 本消防标准不能用于提供定量措施。 1.3 本规范中描述的燃烧器适用于以下ASTM标准:规范 C509型 ，试验方法 D229 ，试验方法 D635 ，试验方法 D876 ，试验方法 D3014 ，试验方法 D3801 ，试验方法 D4804 ，试验方法 D4986 ，以及试验方法 D5048 . 防火测试响应标准的适用性的安全危害和已知限制在单独的测试方法中得到了解决。 注1: 本规范等同于IEC 60695中规定的点火源- 11-3，附录A和IEC 60695-11-4，附录A。 注2: 本规范等同于ISO 10093中规定的P/PF2点火源。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

1.1 This specification covers the physical dimensions and characteristics of a laboratory burner to be used as an ignition source for small-scale burning tests on plastic materials. The burner is used with methane, propane, or butane supply gases for flame heights of 20 to 125 mm. 1.2 This fire standard cannot be used to provide quantitative measures. 1.3 The burner described in this specification is suitable for use in the following ASTM standards: Specification C509 , Test Method D229 , Test Method D635 , Test Method D876 , Test Method D3014 , Test Method D3801 , Test Method D4804 , Test Method D4986 , and Test Method D5048 . Safety hazards and known limitations on applicability of fire-test-response standards are addressed in the individual test methods. Note 1: This specification is equivalent to the ignition source specified in IEC 60695-11-3, Annex A and IEC 60695-11-4, Annex A. Note 2: This specification is equivalent to the P/PF2 ignition source specified in ISO 10093. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
