标准摘要
[中文适用范围]： 本标准规定了磁性测试方法，包括磁场测试方法、磁矩测试方法、充磁和退磁测试方法以及磁补偿测试方法。 本文件适用于多个级别的磁测试：航天器级、子系统级和单元级。 本文件提供了在磁性测试设施提供的零磁场环境和存在地磁场环境下进行磁性测试的指南。 [外文原描述]： ISO 21494:2019 specifies magnetic test methods including magnetic field test methods, magnetic moment test methods, magnetization and demagnetization test methods and magnetic compensation test methods. This document is applicable to magnetic tests on several levels: spacecraft-level, subsystem-level and unit-level. ISO 21494:2019 gives guidelines for conducting magnetic tests both in zero-magnetic field environment provided by magnetic test facilities and in the presence of the geomagnetic field environment.
