IEC 60384-14:20 23适用于打算连接到标称电压不超过1 000 V AC(RMS)、标称频率不超过100 Hz的交流电源或其他电源的电容器和电阻-电容器组合。本文件还包括与额定电压不超过1 500 V DC的DC电源连接的附加具体条件和要求。IEC 60384这一部分的主要目的是规定优选的额定值和特性，从IEC 60384-1中选择适当的质量评估程序、测试和测量方法，并给出这种类型电容器的一般性能要求。参考本部分规范的详细规范中规定的试验严重性和要求具有相同或更高的性能水平；不允许较低的性能水平。本文件还提供了一份安全测试时间表，供需要国家测试站批准的国家的国家测试站使用。本文档中分类的电容器的过电压类别和交流市电电压取自IEC 60664-1。与上一版相比，此版本包括以下重大技术变更: 在湿热稳态试验中，所有电容器类型均在有额定电压和无额定电压下进行试验；增加了试件数量； 仅在安全性测试中，在第0组测试中添加了损耗角的正切； 基于安全和性能测试的资格审批已从正文移至规范性附件； 给出了额定电压的范围，而不是精确的额定电压值；增加了描述电容器类型和爬电距离/间隙距离测量的规范性附件； 在所有相关测试后的操作说明和要求中强调了组件封装中机械故障（裂纹）作为安全特性的重要性。

IEC 60384-14:2023 applies to capacitors and resistor-capacitor combinations intended to be connected to AC mains or other supply with a nominal voltage not exceeding 1 000 V AC (RMS), and with a nominal frequency not exceeding 100 Hz. This document includes also additional specific conditions and requirements for the connection to DC supplies with a rated voltage not exceeding 1 500 V DC. The principal object of this part of IEC 60384 is to prescribe preferred ratings and characteristics and to select, from IEC 60384-1, the appropriate quality assessment procedures, tests and measuring methods and to give general performance requirements for this type of capacitor. Test severities and requirements prescribed in detail specifications referring to this sectional specification are of equal or higher performance level; lower performance levels are not permitted. This document also provides a schedule of safety tests to be used by national testing stations in countries where approval by such stations is required. The overvoltage categories in combination with the AC mains voltages for the capacitors classified in this document are to be taken from IEC 60664-1. This edition includes the following significant technical changes with respect to the previous edition:

1. in damp heat steady state test, all capacitor types are tested both with and without rated voltage; the number of test pieces has been increased;
2. tangent of loss angle is added In Group 0 tests, in safety tests only;
3. qualification approval based on safety and performance tests has been removed from the main text to a normative annex;
4. the range of rated voltages is given instead of exact rated voltage values;
5. normative annex for description of capacitor styles and of creepage/clearance distance measurement has been added;
6. the importance of mechanical failures (cracks) in component encapsulation as a safety feature is highlighted in handling instructions and requirements after all relevant tests.
