抑制电磁干扰用无源滤波装置.第1部分:通用规范

[中文适用范围]： 本通用规范涉及用于在电子或电气设备和机器内使用或与电子或电气设备和机器相关的电磁干扰抑制的无源滤波器单元。一个外壳内的单通道滤波器和多通道滤波器均包含在本通用规范的范围内。由电容元件构成的滤波器（其中电感是滤波器结构中固有的）在本规范的范围内。类似地，由电感元件构造的滤波器（其中电容是滤波器构造中固有的）也在本通用规范的范围内。制造商应说明给定组件是否被设计为电容器、电感器或滤波器。本通用规范范围内的滤波器单元进一步区分为适合安全测试的滤波器单元（例如连接到市电电源的滤波器单元）和不适合此类测试的滤波器单元。单独的分规范涵盖了适合进行安全测试的无源滤波器单元。该通用规范建立了电子元件 IECQ-CECC 系统内分部规范和详细规范中使用的标准术语、检验程序和测试方法。 [外文原描述]： IEC 60939-1:2010 relates to passive filter units for electromagnetic interference suppression for use within, or associated with, electronic or electrical equipment and machines. Both single and multi-channel filters within one enclosure are included within the scope of this generic specification. This generic specification establishes standard terms, inspection procedures and methods of test for use in sectional and detail specifications within the IECQ-CECC system for electronic components. This edition includes the following significant technical changes with respect to the previous edition: a) table 3 has been updated, specifying how to handle the Neutral by 3-phase filter with Neutral; b) all details about "Quality assessment" have been deleted in this edition, because this standard is a safety standard; c) filters shall be subjected to Test Aa of IEC 60068-2-1 for 16 h, using the degree of severity of the lower category temperature as prescribed in the relevant specification; d) since IEC 60068-2-20 does no longer make a difference between Method 1A and 1B, but only describes Method 1, references to the method to be used are updated.
