1.1 这种火灾试验响应试验方法 2. 介绍了使用热风炉对塑料的闪燃温度和自燃温度的实验室测定。 1.2 以国际单位制表示的数值应视为标准。本标准中不包括其他计量单位。 1.3 小心- 在燃烧过程中，会产生可能对人员造成危险的气体或蒸汽，或两者兼而有之。 1.4 本标准用于测量和描述材料、产品或组件在受控条件下对热量和火焰的响应，但其本身并未包含火灾所需的所有因素- 材料、产品或组件在实际火灾条件下的危险或火灾风险评估。 1.5 火灾测试具有内在的危险性。在进行这些试验时，应对人员和财产采取充分的保护措施。 1.6 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 具体的预防说明见 1.3 和 1.4 。 注1: 该试验方法和ISO 871-2022（选项1）在所有技术细节上相似。 1.7 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 4.1 在本文规定的条件下进行的测试在比较不同材料的相对点火特性方面具有相当大的价值。 所获得的值表示在本试验条件下会导致材料着火的最低环境空气温度。试验值应根据实际使用条件下的着火敏感性对材料进行分级。 4.2 本试验并非火灾危险的唯一标准。除了点火温度外，火灾危险还包括其他因素，如燃烧速率或火焰蔓延、燃烧强度、燃料贡献、燃烧产物等。

1.1 This fire test response test method 2 covers a laboratory determination of the flash ignition temperature and spontaneous ignition temperature of plastics using a hot-air furnace. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 Caution— During the course of combustion, gases or vapors, or both, are evolved that have the potential to be hazardous to personnel. 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-hazard or fire-risk assessment of the materials, products, or assemblies under actual fire conditions. 1.5 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests. 1.6 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in 1.3 and 1.4 . Note 1: This test method and ISO 871-2022 (Option 1) are similar in all technical details. 1.7 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. ====== Significance And Use ====== 4.1 Tests made under conditions herein prescribed can be of considerable value in comparing the relative ignition characteristics of different materials. Values obtained represent the lowest ambient air temperature that will cause ignition of the material under the conditions of this test. Test values are expected to rank materials according to ignition susceptibility under actual use conditions. 4.2 This test is not intended to be the sole criterion for fire hazard. In addition to ignition temperatures, fire hazards include other factors such as burning rate or flame spread, intensity of burning, fuel contribution, products of combustion, and others.
