着火危险试验.第6-31部分:烟雾遮蔽.小规模静态试验.材料

[中文适用范围]： 本部分IEC 60695描述了用于确定电气产品中使用的材料产生的烟雾特定光密度的测试方法，使用技术规范IEC/TS 60695-6-30中描述的装置。试样在封闭室（即无空气置换）中垂直暴露于辐射热源，可选择是否应用预燃火焰。测试方法仅适用于电气产品中使用的平面、固体、非金属试样。本技术规范不提供材料行为的分类系统。测试方法不适用于熔化并从热流直接冲击区域流走的材料。由于物理火灾模型的局限性和试样的几何形状，不建议将此测试方法进一步用于电气产品的开发，也不建议将其作为电气产品烟雾释放监管或其他控制的依据。警告：应采取适当的安全措施，因为试样的热解或燃烧可能产生有毒和有害的火灾产物。本基本安全出版物旨在供技术委员会在根据IEC导则104和ISO/IEC导则51中规定的原则编制标准时使用。技术委员会的责任之一，在适用时，是在编制其出版物时使用基本安全出版物。除非在相关出版物中明确引用或包含，否则本基本安全出版物的要求、测试方法或测试条件不适用。 [外文原描述]： IEC/TS 60695-6-31:2013 describes the test methods for the determination of the specific optical density of smoke produced by materials used in electrotechnical products using the apparatus described in technical specification IEC/TS 60695-6-30. Test specimens are exposed vertically to a radiant heat source with or without the application of a pilot flame in a closed chamber (i.e. without air-change). The test methods are only applicable to flat, solid, non-metallic test specimens of materials used in electrotechnical products. This technical specification does not provide a classification system for the behaviour of materials. The test methods are not applicable to materials which melt and flow away from the direct impingement of heat flux. The test methods are not recommended for further development for electrotechnical products, nor are they recommended as the basis for regulation or other controls on smoke release due to the limitations of the physical fire model and the test specimen geometry - see Clause 4. This second edition cancels and replaces the first edition published in 1999. It constitutes a technical revision. The main changes with respect to the previous edition are: - the Foreword has been revised and updated, - the Introduction has been updated, - the Scope has been updated - the Normative references have been updated, - minor technical changes have been made throughout the document, and - detailed editorial updates have been added throughout the document. It has the status of a basic safety publication in accordance with IEC Guide 104 and ISO/IEC Guide 51. Keywords: Fire Hazard testing, Smoke obscuration. This publication is to be read in conjunction with IEC 60695-6-30:1996 .
