本标准规定了在对真空灭弧室和包含真空灭弧室的开关设备进行高压试验时，将影响人员的x射线发射保持在可接受极限的试验条件和程序。本标准涵盖工厂测试、现场调试、在役测试，并规定了实施这些程序的责任链。

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.
