scope:

This standard specifies the technical requirements for a sensitive safety voltage detector (hereinafter referred to as the 'equipment'), safe to use in the presence of explosives for for indicating the existence of any spurious a.c /d.c voltages that may appear in a firing circuits of electrically initiated explosive devices (EED).

Accuracy shall be maintained over a wide temperature and humidity range

The equipment shall be safe and reliable to use in the presence of strong electro-magnetic and/or electrostatic fields, provided that appropriate connectors and associated leads are used.

It shall be possible at any time to prove that the circuit under test is connected and That the equipment is serviceable without disturbance of the connections.
