着火危险测试.第2-11部分:基于灼热/发热丝的试验方法.最终产品的灼热丝易燃性试验方法(GWEPT)

[中文适用范围]： IEC 60695 的这项规定了在最终产品上进行的试验方法。其目的是模拟由电热源产生的热应力的影响，以代表火灾危险。该方法用于检查在规定的试验条件下，暴露于电热源下的最终产品是否要么具有有限的点燃能力，要么在点燃后具有有限的火焰蔓延能力。然而，火灾危险分析、易燃性以及火焰蔓延到其他产品不在本标准的范围内。本基本安全出版物旨在供技术委员会在依据 IEC Guide 104 和 ISO/IEC Guide 51 制定的原则编制标准时使用。技术委员会的职责之一是，在适用时，在编制其出版物时利用基本安全出版物。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、试验方法或试验条件将不适用。 [外文原描述]： 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 otherproducts 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. Key words: Glowing/hot-wire, Glow wire, Flammability, Fire hazard This publication is to be read in conjunction with IEC 60695-2-10:2013 .
