IEC 62677-2:20 17给出了一系列配置和材料的热收缩低压和中压模制形状的测试方法，这些配置和材料适用于连接器/电缆终端和多路过渡的绝缘、环境密封、机械保护和应变消除。 规定的测试旨在控制模制形状的质量，但应认识到，它们设计用于低压和中压电缆附件，因此电气性能将作为组件的一部分得到验证。在EN 50393、HD 629.1和IEC 60502-4中描述了这方面的示例。

IEC 62677-2:2017 gives methods of test for heat shrinkable low and medium voltage moulded shapes in a range of configurations and materials suitable for insulation, environmental sealing, mechanical protection and strain relief for connector/cable terminations and multi-way transitions.
The tests specified are designed to control the quality of the moulded shapes but it is recognized that they are designed to be used in low and medium voltage cable accessories and as such electrical performance will be proven as part of the assembly. Examples of this are described in EN 50393, HD 629.1 and IEC 60502-4.
