scope:

In this Defence Standard the DOSG publish the principles that they recommend for the design and use of electrical circuits and software in systems which incorporate or control explosive components and against which they will assess designs. They also publish the methods and techniques that they will use when assessing the safety of such circuits and software and make recommendations on safety margins and trials factors that should be used. They also identify the electrical and electromagnetic environments and the nature of the problems involved in the design and operation of systems with Electro-explosive Devices (EED).

This part identifies those types of EED currently used in service, their characteristics and methods of determining their electrical parameters and characteristics.
