- Scope
- This International Standard specifies the procedure for a radio interference (Rl) test carried out in a laboratory on clean and dry insulators at a frequency of 0,5 MHz or 1 MHz or, alternatively, at other frequencies between 0,5 MHz and 2 MHz. In service the Rl characteristics of an insulator may be modified by the ambient conditions, particularly rainfall and other moisture, and by pollution. It is not considered feasible to specify reproducible test conditions to simulate a range of ambient conditions. Hence only tests on clean and dry insulators are specified in this standard. NOTE - The effects of insulator surface conditions, including pollution, are presented in Amendment 1 of CISPR 18-2.
