BS EN IEC 60230:2018 defines the procedure for carrying out withstand lightning and switching impulse tests and withstand superimposed impulse test on cables and their accessories. This document applies solely to the methods of carrying out the tests as such, independently of the problem of selecting the test levels to be specified.
The voltages pertaining to the system on which cables and accessories are to be used are given in IEC 601 83 or in the relevant product standard. This document specifies the following requirements:
• the characteristics and state of the test installation and those parts of the procedure which are common to withstand tests and tests above the withstand level;
• the procedure for carrying out withstand lightning and switching impulse tests and superimposed impulse test;
• the procedure for carrying out tests above the withstand level which is intended for research purposes.
