标准摘要
[中文适用范围]： 本部分 IEC 60317 规定了单涂层基于聚乙烯醇缩醛或聚乙烯醇缩甲醛（在保留原始树脂化学身份且满足所有规定线规要求的前提下可进行改性）的 120 级 enamelled round copper winding wire（漆包圆铜线）的要求。 [外文原描述]： IEC 60317-12:2020 specifies the requirements of enamelled round copper winding wires of class 120 with a sole coating based on polyvinyl acetal or polyvinyl formal resin, which can be modified provided it retains the chemical identity of the original resin and meets all specified wire requirements. NOTE 1 A modified resin is a resin that has undergone a chemical change, or contains one or more additives to enhance certain performance or application characteristics. NOTE 2 Polyvinyl acetal is a general name for a family of thermoplastic vinyl resins produced by the condensation of polyvinyl alcohol with an aldehyde. Examples are polyvinyl acetal, polyvinyl formal and polyvinyl butyral. The range of nominal conductor diameters covered by this document is: - Grade 1: 0,040 mm up to and including 2,500 mm; - Grade 2: 0,040 mm up to and including 5,000 mm; - Grade 3: 0,080 mm up to and including 5,000 mm. The nominal conductor diameters are specified in Clause 4 of IEC 60317-0-1:2013. This fourth edition of IEC 60317-12 cancels and replaces the third edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - modification of the Scope; - addition of reference to transformer oil resistance test method in Clause 20.
