scope:

This Standard outlines the typical electromagnetic environmental requirements for electrical/electronic equipment used in the Services and guidance is given covering documentation which ensures management and control procedures are implemented during all acquisition stages of any given project.

This Standard does not address exceptionally severe electromagnetic situations (e.g. equipment mounted on the mast of a warship). The severity of these environments should be established by modelling, prediction or measurement, see Clause 4 and Part 2. The test limits should then be tailored accordingly.

This Standard gives some guidance and more stringent levels for safety critical systems it shall not be considered a safety standard. Any safety related advice given in this standard, forms part of a Safety Case and should not be used in isolation.

This Standard also includes some simulated Nuclear Electromagnetic Pulse (NEMP), lightning strike and electrostatic discharge tests at Line Replacement Unit (LRU) level.

This Standard is not concerned with the clearance of radio frequencies, performance tests on communication equipment (antenna port EMC tests are however included) or the direct ignition of fuel/ordnance by electromagnetic energy. Guidance on these can be sought from E3A ( See Single Point of Contact), Joint Spectrum Authority (JSA) or Defence Ordnance Safety Group (DOSG).

This Part of the Defence Standard provides advice on the selection of EMC requirements for all military equipment and the application of the complete Standard throughout all phases of the acquisition process. It concentrates that advice under the following headings:

a) operational scenario and the electromagnetic environment;

b) specification of EMC contractual requirements;

c) control and management of EMC;

d) management roles and responsibilities;

e) EM control plan;

f) EM test plan;

g) EM test report;

h) EM Test Certificate;

i) selection of tests;

j) selection of limits;

k) total system trials requirements;

l) post design services requirements;

m) in-service maintenance;

n) change of role;

o) health and safety.

To cater for particular interests of each of the three Service Arms of the MOD, their special requirements are noted as they arise, under the headings above.

The default Defence Standard 59-411 contract requirements and Project Managers checklist is given in Annex H.

Although Part 1 is concerned primarily with EMC, the management and control procedures described can be applied across the E3 disciplines e.g. EMC, EMP, Radio Hazards (RADHAZ), TEMPEST, Electronic Counter Measures (ECM), etc. The MOD should ensure that their Prime Contractor recognises and exploits the economies arising from the degree of commonality which exists between EMC and these kindred subjects, with respect to equipment design, management and control procedures, and even test requirements where possible.

Within the Land Environment, DSTL have produced and maintain a FP ECM EMC Control Plan (Ref Dstl/DOC33211 and Dstl/Dstl/DOC82354 for Explosive Ordnance Disposal (EOD) ECM). This Control Plan is a 'living' document and as such will be maintained as necessary to reflect the evolution of the FP ECM project. The FP ECM EMC Control Plan should be called up in all FP ECM contracts for EMC requirements.

The purpose of the FP ECM EMC Control Plan is to organise and document the methods that will be used to identify and mitigate EMC risks for FP ECM equipments and installation kits. This EMC Control Plan is in advance of formal specifications; however, priority will be given to managing EMC risks and performance in the following order:

a) safety e.g. platform driver and safety system control, weapon control and operation, RADHAZ to electro-explosive devices (EEDs), RADHAZ to personnel, RADHAZ to fuels and lubricants, functioning of scenario safety related systems, etc.;

b) performance of FP ECM equipment;

c) interoperability with communications equipment;

d) platform installed mission critical systems;

e) interoperability with other scenario equipment and systems;

f) security.

The control plan defines the management and engineering procedures and techniques that are used to control EMC and EMC related design and validation activities. It details specific requirements and tailored limits to meet the various EMC operational environments and all safety requirements with specific consideration given to platform integration.

Should additional advice be required, this can be obtained either from the Equipment Sponsor or from E3A (See single point of contact).
