本文件规定了磁性材料磁芯机械强度的试验方法 氧化物。本试验方法适用于大多数E型芯、ETD型芯、I型芯和环形芯 但其他类型的岩心，如U型岩心，可以根据衍生方法进行测试 经有关各方同意。本文件也适用于机械强度 磁粉芯的测量。购买本文件时可获得的所有当前修订均包含在购买本文件中。

This document 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 ringcores 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.All current amendments available at time of purchase are included with the purchase of this document.
