磁性氧化物磁芯机械强度的试验方法

[中文适用范围]： 本文件规定了磁性氧化物制成的磁芯机械强度的测试方法。该测试方法适用于大多数E型磁芯、ETD型磁芯、I型磁芯和环形磁芯，但其他类型的磁芯（如U型磁芯）可根据相关方商定的派生方法进行测试。本文件也适用于磁性粉末磁芯的机械强度测量。 [外文原描述]： IEC 61631:2020 specifies a test method for the mechanical strength of cores made of magnetic oxides. This test method is suitable for most of the E-cores, ETD-cores, I-cores and ring-cores but other core types such as U-cores could be tested according to a derived method agreed by the parties concerned. This document is also applicable to the mechanical strength measurement of magnetic powder cores. This edition includes the following significant technical changes with respect to the previous edition: - the phrase: "This document is also applicable to the mechanical strength measurement of magnetic powder cores" has been added in the scope; - IEC 61246 has been replaced by IEC 63093-8; EN 1002-2 has been replaced by ISO 7500-1; ISO 4677-1 and ISO 4677-2 have been withdrawn; - dimensions D and F in Figure A.1 and Table A.1 have been changed to be consistent with Figure 1 of IEC 63093-8:2018; - addition of the content of ring-cores test; - addition of Annex B; - the location of the jig is amended in Figure 3; - in Figure 5, the roller bars are moved to the edge of the I-core, aligned with the core.
