标准范围

IEC 60939-3:2015涵盖了用于衰减电磁源产生的不需要的射频信号（如噪声或干扰）的无源滤波器。本规范的范围包括一个外壳内的单通道和多通道滤波器，或构建在构成紧凑实体的印刷电路板上的单通道和多通道滤波器。本规范适用于适用于安全测试的电磁干扰抑制无源滤波器单元。这意味着，当需要符合表3中的强制性试验时，根据本规范规定的过滤器将连接到主电源，或者在设备规范规定需要进行部分或全部安全试验的其他电路位置使用。本规范适用于无源滤波装置，其将连接至标称电压不超过1000 V a的交流电源或其他电源（直流或交流）。c、 标称频率不超过400 Hz或1500 V直流电。

IEC 60939-3:2015 covers passive filters used to attenuate unwanted radio-frequency signals (such as noise or interference) generated from electromagnetic sources. Both single and multi-channel filters within one enclosure or which are built on a printed circuit board forming a compact entity are included within the scope of this specification. This specification applies to passive filter units for electromagnetic interference suppression for which safety tests are appropriate. This implies that filters specified according to this specification will either be connected to mains supplies, when compliance with the mandatory tests of Table 3 is necessary, or used in other circuit positions where the equipment specification prescribes that some or all of these safety tests are required. This specification applies to passive filter units, which will be connected to an a.c. mains or other supply (d.c. or a.c.) with a nominal voltage not exceeding 1 000 V a.c., with a nominal frequency not exceeding 400 Hz, or 1 500 V d.c.
