This Tri-service Design and Installation Code of Practice provides guidance to Project Managers and Design Team Members in industry as well as to Project Managers and Advisors in MOD. It provides guidance for all phases of design from initial concept through to in service maintenance and modification.

This Part of the Defence Standard is applicable to all electrotechnical equipment and installations (to be installed in Air Platforms, Land Vehicles, Surface Ships and Submarines).

This Standard is only intended to provide guidance on the electromagnetic compatibility of equipment and systems and their installation, and other aspects including safety, reliability and maintainability must be taken into account when applying the recommended measures.

EMC test methods and limits are covered in Parts 3 and 4 of this Standard.

The measures recommended for achieving EMC will also assist in providing Nuclear Electromagnetic Pulse (NEMP) Hardening and lightning (LEMP) hardening.

Severe EMC problems are likely to arise in non-metallic platforms i.e. ships, (e.g. glass reinforced plastic) requiring special techniques to be adopted. Specific platform requirements related to the electromagnetic scenario are discussed in the three service annexes as appropriate.
