- Scope
- This standard specifies the requirements, tests, quality plans, markings, etc. for nuclear phase instruments used in live operations. This standard applies to portable phase nuclear instruments used in power systems with or without power supply. The voltage range is AC 1~35kV. This standard also applies to double-rod phase nuclear analyzers with leads, double-rod type nuclear reactors without leads, and single-rod phase nuclear analyzers with storage systems, as long as they are in contact with the part being tested, the overall structure or insulation Nuclear phase analyzer with rod separation. This standard does not include phase nuclear devices for voltage detection and phase comparison.
