请注意:此版本的所有临时修订版将在您购买时提供。1.1范围本规范涵盖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。由电容元件构成的滤波器，其中电感是滤波器构造中固有的，在本规范的范围内。 同样，由电感元件构成的滤波器，其电容是滤波器结构中固有的，也在本规范的范围内。这取决于制造商是否将给定组件设计为电容器、电感器或滤波器。滤波器还可以包括其他组件，如电阻器和/或变阻器或类似组件。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.c.，标称频率不超过400 Hz的交流电源或其他电源（直流或交流）。注:对于交流使用，IEC 60384-14适用于将连接至标称频率不超过100 Hz的交流电源的电容器。本规范涵盖设备过滤器（美国），但不包括设施过滤器、线缆连接过滤器或直接插入式过滤器。这些其他过滤器将包含在另一个分规范中。

Please note: All interim revisions for this edition available at time of your purchase will be included.1.1 ScopeThis specification 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.Filters constructed of capacitive elements where the inductance is inherent in the construction of the filter are within the scope of this specification. Similarly, filters constructed of inductive elements where the capacitance is inherent in the construction of the filter are also within the scope of this specification. It is up to the manufacturer to state whether a given component is to be designed as a capacitor, an inductor or a filter. Filters can include also other components like resistors and/or varistors or similar components.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.NOTE For a.c. use, IEC 60384-14 applies to capacitors which will be connected to a.c. mains with a nominal frequency not exceeding 100 Hz.This specification covers appliance filters (US) but does not cover facility filters, cord-connected filters or direct plug-in filters. These other filters will be covered by another sectional specification.
