This standard mainly deals with two interference coupling paths, namely ground and power supply. This standard gives common interference levels, test methods for anti-interference performance of a single instrument and system before and after installation, and specifies the allowable limit value as a test criterion for single instrument and system installation. This standard applies to reactor nuclear instruments that are very sensitive to electromagnetic interference and related to safety.
