[中文适用范围]： IEC 60404-11:2021 适用于单面或双面涂覆绝缘层的电工钢带和薄片。本文件的目的是定义电工钢带和薄片表面绝缘电阻测量的通用原则和技术细节。注：该测试适用于绝缘涂层应用中的制造和质量控制。 [外文原描述]： IEC 60404-11:2021 is applicable to electrical steel strip and sheet insulated by coating on one or both sides. The object of this document is to define the general principles and technical details of the measurement of the surface insulation resistance of electrical steel strip and sheet. NOTE This test is suitable for manufacturing and quality control in the application of insulation coatings. This edition includes the following significant technical changes with respect to the previous edition: Method B has been deleted and the measurement of individual currents through each contact button is enabled by Method A; an improved arrangement of the test apparatus and the voltage stabilizing circuit for Method A, “Arrangement B”, is introduced. an alternative layout using two pairs of contact assemblies in opposing position of the test specimen is introduced; the restriction: “The same area of the test specimen shall not be used to test both sides.” has been deleted.
