IEC 60352-7:20 20作为IEC 60352-7:20 20 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。 IEC 60352-7:20 20适用于用剥线制成的弹簧夹连接，无需进一步准备: -标称直径为0.32毫米至3.7毫米（横截面为0.08毫米至10毫米）的实心导体，或 -横截面为0.08 mm2至10mm2的绞合导体，或 -横截面为0.08 mm2至10mm2的柔性导体， 根据IEC 60228或IEC 60189-3，用于电气和电子设备和组件。 除了测试程序之外，还包括有关材料和工业经验数据的信息，以在规定的环境条件下提供电气稳定的连接。本文件的目的是确定弹簧夹连接在规定的机械、电气和大气条件下的适用性。第二版取消并取代了2002年发布的IEC 60352-7第一版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更: a)图6和图7两个流程图的修正， b)将内容拆分为更多的条款，以便在完整测试时间表和基本测试时间表之间更好地分离， c)将前第6条实用指南的内容重新定位到信息性附件A中，就像现在在IEC 60352系列中用于无焊连接的常见内容一样， d)参考IEC 60228中定义的类别澄清导体类型。

IEC 60352-7:2020 is available as IEC 60352-7:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60352-7:2020 is applicable to spring clamp connections made with stripped wire without further preparation:
- solid conductors of 0,32 mm to 3,7 mm nominal diameter (0,08 mm2 to 10 mm2 cross？section), or
- stranded conductors of 0,08 mm2 to 10 mm2 cross-section, or
- flexible conductors of 0,08 mm2 to 10 mm2 cross-section,
according to IEC 60228 or IEC 60189-3 for use in electrical and electronic equipment and components.
Information on materials and data from industrial experience is included in addition to the test procedures to provide electrically stable connections under prescribed environmental conditions. The object of this document is to determine the suitability of spring clamp connections under specified mechanical, electrical and atmospheric conditions. This second edition cancels and replaces the first edition of IEC 60352-7, published in 2002. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) correction of the two flow charts in Figure 6 and Figure 7,
b) split the content into more clauses for better separation between full test schedule and basic test schedule,
c) relocating the content of former Clause 6 Practical guidance into an informative Annex A, as now common in the IEC 60352 series for solderless connections,
d) clarification on conductor types with reference to classes defined in IEC 60228.
