Magnetic materials - Part 11: Methods of measurement of the surface insulation resistance of electrical steel strip and sheet
| 분야 | TC 68 : Magnetic alloys and steels |
|---|---|
| 적용범위 | 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. |
