Sets out conditions for carrying out high voltage tests on vacuum interrupters and switchgear incorporating vacuum interrupters for the protection of personnel from X-ray emission. Outlines situations where precautions may be necessary, and methods for measuring or monitoring X-ray emission.

This Standard sets out the conditions for carrying out high voltage tests on vacuum interrupters and switchgear incorporating vacuum interrupters for the protection of personnel from X-ray emission. The Standard covers factory testing, on-site commissioning and in-service testing.It outlines situations where such precautions may be necessary, and establishes methods by which measurement of X-ray emission may be made.
