标准摘要
[中文适用范围]： 本部分IEC 60695是一项技术规范，描述了适用于可提供试样的固体电绝缘材料的测试方法。该测试测量试样在受到缠绕在其上的电加热线加热影响时点燃所需的时间。 该测试方法可用于提供分类，可用于质量保证、如IEC 60695-1-30所述的产品材料预选，或验证最终产品中使用的材料所需的最低分类。 本基本安全出版物旨在供技术委员会根据IEC指南104和ISO/IEC指南51中规定的原则制定标准时使用。技术委员会的职责之一是在适用的情况下，在其出版物的编制中使用基本安全出版物。除非在相关出版物中具体引用或包含，否则本基本安全出版物的要求、测试方法或测试条件将不适用。 [外文原描述]： IEC TS 60695-2-20:2024 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 TS 60695-2-20:2024, which is a technical specification, describes a test method that applies to solid electrical insulating materials of which test specimens can be provided. The test measures the time required to ignite a test specimen when it is affected by heat from an electrically heated wire wound around the test specimen. The test method can be used to provide classifications which can be used for quality assurance, the preselection of materials of products as described in IEC 60695-1-30, or to verify the required minimum classification of materials used in end products. This fourth edition cancels and replaces the third edition published in 2021. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: Removed all text which was related to drip or dripping, since in this 4th edition only ignition is taken into consideration for determination of the classification level; Title changed: "Hot wire coil test method" is now "Hot wire ignition (HWI) test method".
