1.1 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 from 600 V to 800kV with frequency of 60 Hz. The function of the voltage detector is limited to the detection of the presence or absence of nominal operating voltage.

1.1.1 This specification is not applicable to other types of voltage detectors.

1.2 The use and maintenance of these high voltage detectors and any necessary insulated tool handles are beyond the scope of this specification.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
