This specification covers portable, live-line tool-supported, direct-contact type capacitive voltage detectors to be used on electrical systems both indoors and outdoors for ac voltages. This specification establishes requirements for the design and testing of high voltage detectors, used in the electrical power industry, to determine the presence or absence of nominal operating voltage. The following tests shall be performed: voltage; low temperature impact; drop/impact; humidity; wet test; battery life test; durability of labeling; vibration resistance; continuous operation rating; response time; testing the self-test function; acceptable audible indication; acceptable visual indication; visual inspection; method to measure threshold voltage; interference voltage testing; leakage current testing; dielectric testing for detector housing; and wet testing.
