火灾危险测试 第 2-11 部分：基于灼热丝/热丝的测试方法 最终产品的灼热丝可燃性测试方法 (GWEPT)

[中文适用范围]： IEC 60695-2-11:2014 RLV 包含官方 IEC 国际标准及其红线版本。 Redline 版本仅提供英文版本，为您提供了一种快速、简单的方法来比较官方 IEC 标准与其先前版本之间的所有更改。 IEC 60695-2-11:2014 规定了最终产品的测试方法。它旨在模拟电加热源产生的热应力的影响，以代表火灾危险。该测试方法用于检查在规定的测试条件下，暴露于电热源的最终产品是否具有有限的点燃能力，或者如果点燃，则传播火焰的能力有限。然而，火灾危险分析、可燃性方面以及火焰向其他产品的蔓延不属于本标准的范围。 IEC 60695-2-11 第二版取消并取代了 2000 年发布的 IEC 60695-2-11 第一版。它构成了技术修订。相对于前一版本的主要变化是： - 添加了引言以提供背景及其与范围的关系， - 为了更加清晰并参考基本安全出版物，对范围进行了修改， - 大量相关术语和定义本标准第3条增加了： ——介绍并明确了“小零件”和“微不足道质量”的应用， ——进一步规定了不同类型的试样、如何规定它们以及试验方法的限制在第 4 条中进行了澄清， - 在第 5 条中澄清了未知时到指定层的距离， - 第 6 条中的信息已移至第 8 条中的测试程序中， - 澄清了指定层的调节和实验室环境测试条件在第 7 条中， - 从第 9 条中删除了最大火焰高度的测量， - 引入了对该测试的引用“GWEPT”以及适用的标题更改，并且 - 附录 A 已修订，以反映著名产品委员会的当前实践。本出版物应与 IEC 60695-2-10:2013 一起阅读。 [外文原描述]： IEC 60695-2-11:2014 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60695-2-11:2014 specifies a test method on an end product. It is intended to simulate the effects of thermal stresses produced by an electrically heated source to represent a fire hazard. This test method is used to check that, under defined test conditions, an end product exposed to an electrically heated source has either a limited ability to ignite or, if it ignites, a limited ability to propagate flame. However, the fire hazard analysis, the flammability aspects and the flame spreading to other products are not covered by the present standard. This second edition of IEC 60695-2-11 cancels and replaces the first edition of IEC 60695-2-11 published in 2000. It constitutes a technical revision. The main changes with respect to the previous edition are: - the Introduction has been added to provide background and how it relates to the Scope, - the Scope has been modified for greater clarity and reference to basic safety publications, - numerous terms and definitions relevant to this Standard have been added to Clause 3, - the application of "small parts" and "insignificant mass" have been introduced and clarified, - the different types of specimens, how to specify them, and limitations of the test method have been further clarified in Clause 4, - clarified in Clause 5 the distance to specified layer when unknown, - the information from Clause 6 has been moved into the test procedure in Clause 8, - the conditioning of the specified layer and the laboratory ambient test conditions were clarified in Clause 7, - measurement of the maximum flame height was removed from Clause 9, - the reference to this test as "GWEPT" was introduced along with an applicable title change and - Annex A has been revised to reflect current practice by prominent product committees. This publication is to be read in conjunction with IEC 60695-2-10:2013 .
