标准摘要
[中文适用范围]： IEC 60404-5:2015 RLV 包含官方 IEC 国际标准及其红线版本。 Redline 版本仅提供英文版本，为您提供了一种快速、简单的方法来比较官方 IEC 标准与其先前版本之间的所有更改。 IEC 60404-5:2015定义了永磁材料磁通密度、磁极化和磁场强度的测量方法，并确定了永磁材料的退磁曲线和反冲线。与前一版本相比，该版本包括以下重大技术变化： - 测量方法和测试条件适用于新推出的矫顽力值 HcJ 高于 2 MA/m 的硬磁材料； - 更新了温度条件，以允许测量具有高温度系数的新材料。 [外文原描述]： IEC 60404-5:2015 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60404-5:2015 is to define the method of measurement of the magnetic flux density, magnetic polarization and the magnetic field strength and also to determine the demagnetization curve and recoil line of permanent magnet materials. This edition includes the following significant technical changes with respect to the previous edition: - adaption of the measurement methods and test conditions to newly introduced magnetically hard materials with coercivity values HcJ higher than 2 MA/m; - update of the temperature conditions to allow the measurement of new materials with high temperature coefficients.
