Division 3.3 Detonators (including delay detonators) and relays shall also comply with the following requirements:

detonators must reliably initiate the detonation of the blasting explosives which are intended to be used with them under all foreseeable conditions of use;

delay connectors for detonating cords must be reliably initiated;

the initiation capability must not be adversely affected by humidity;

the delay times of delay detonators must be sufficiently uniform to ensure that the probability of overlapping of the delay times of adjacent time steps is insignificant;

the electrical characteristics of electric detonators must be indicated on the packaging (e.g. no-fire current, resistance);

the wires of electric detonators must be of sufficient insulation and mechanical strength including the solidity of the link to the detonator, taking account of their intended use.
