标准范围

IEC 60938-1:20 21适用于设计用于抑制电磁干扰的电感器，旨在用于所有类型的电气和电子设备。在本通用规范中，给出了规范性参考文献以及术语和定义。它还规定了干扰抑制电感器的一般要求和适当的测试和测量程序。附录B规定了接地电感的特殊要求。与上一版相比，此版本包括以下重大技术变更:a)增加了材料测试；b)提高了通用规范中的测试描述和分段规范中的要求之间的可读性和清晰的分离；c)爬电距离和间隙要求现在仅在截面规范中定义；d)包括电压测试的交流测试。

IEC 60938-1:2021 applies to inductors designed for electromagnetic interference suppression intended for use within all kind of electric and electronic equipment.
In this generic specification, normative references and terms and definitions are given. It also prescribes general requirements and the suitable test and measurement procedures for interference suppression inductors. Annex B states special requirements for earth inductors.
This edition includes the following significant technical changes with respect to the previous edition:
a) material tests added;
b) improved readability and clear separation between test descriptions in the generic spec and requirements in the sectional specification;
c) creepage and clearance requirements are now defined in sectional specifications only;
d) AC testing for voltage test included.
