Introduction

This Section of the Defence Standard describes the preferred techniques to be used for the measurement of the electromagnetic compatibility characteristics of Man Worn and Man Portable electrical and electronic equipment to be procured by the Ministry of Defence. Although EMC measurements are usually specified in terms of absolute units, precise measurement is often difficult, the result depending on the method used. In the interests of repeatability, therefore, the preferred methods should be used. Alternative measurement techniques to those described in this Standard may be permitted but only if their equivalence can be demonstrated to the satisfaction of the Procuring Authority. Any deviations fiom the practices laid down in this Standard shall be recorded and included with the test results.

The tests are grouped under headings relating to conducted emission and susceptibility, radiated emission and susceptibility, electrostatic discharge. All electrical equipment shall be subjected to emission testing but only those incorporating electronics shall be subjected to susceptibility testing. In some equipment applications additional tests may be required and it is the responsibility of the Procuring Authority to ensure that such tests are specified in the Test Plan.

The tests described are not intended to be regarded as production tests, although they may in certain circumstances be suitable for this purpose.
