标准范围

IEC 60695-2-12:20 10规定了适用于固体电绝缘材料或其他固体材料的测试样品的可燃性测试，以确定辉光线可燃性指数(GWFI)。GWFI是在该标准化程序中确定的最高温度，在该温度下，测试材料；不点燃，或者，如果点燃，在移除发光丝后30秒内熄灭，并且没有完全消耗，熔化的液滴（如果发生）不会点燃包裹组织。本标准应与IEC 60695-2-10和IEC 60695-2-13结合使用。第二版包括与上一版相比的以下重大技术变化:-修改标题；-添加引言；-澄清范围；-第2条的扩展:规范性参考文献；-加入第3条的定义；-修订第4条以与IEC 60695-11系列保持一致，引入材料变化测试程序指南；-澄清第8条:调节（现为第7条）；-删除第9条“初始测量”；-扩展条款10:测试程序（现为条款8）；-扩大第11条:观察和测量（现为第9条）；-澄清第12条:测试结果的评估（现为第10条）；-扩展条款13:测试报告（现为条款11）。根据IEC指南104和ISO/IEC指南51，本标准具有基本安全出版物的地位。本出版物应与IEC 60695-2-10:20 00和IEC 60695-2-13:20 10一起阅读。

IEC 60695-2-12:2010 specifies the details of the glow-wire test to be applied to test specimens of solid electrical insulating materials or other solid materials for flammability testing to determine the glow-wire flammability index (GWFI). GWFI is the highest temperature, determined during this standardized procedure, at which the tested material; does not ignite or, if it does, extinguishes within 30 s after removal of the glow-wire and is not totally consumed, and molten drips, if they occur, do not ignite the wrapping tissue. This standard is to be used in conjunction with IEC 60695-2-10 and IEC 60695-2-13. This second edition includes the following significant technical changes from the previous edition:
- modified title;
- addition of an Introduction;
- clarification of Scope;
- expansion of Clause 2: Normative references;
- definitions added to Clause 3;
- revision of Clause 4 to alignment with the IEC 60695-11 series to introduce guidance on test programs for material variations;
- clarification of Clause 8: Conditioning (now Clause 7);
- deletion of Clause 9 "Initial measurements";
- expansion of Clause 10: Test procedures (now Clause 8);
- expansion of Clause 11: Observation and measurement (now Clause 9);
- clarification of Clause 12: Evaluation of test results (now Clause 10);
- expansion of Clause 13: Test report (now Clause 11).
This standard has the status of a basic safety publication in accordance with IEC Guide 104 and ISO/IEC Guide 51.

This publication is to be read in conjunction with IEC 60695-2-10:2000 and IEC 60695-2-13:2010.
