The Standard provides testing conditions and procedures to keep the emission of x-rays affecting personnel to acceptable limits in the carrying out of high voltage testing on vacuum interrupters and switchgear incorporating vacuum interrupters. The Standard covers factory testing, on-site commissioning, in-service testing and specifies that a chain of responsibility be established for the implementation of these procedures.
