BS EN 50498:2010 specifies limits and methods of measurement for disturbance emissions and
immunity characteristics of aftermarket equipment (ESAs) which are referenced by Automotive EMC Directive 2004/104/EC, Annex I, 3.2.9, and which are not related to immunity-related functions of vehicles as defined in Automotive EMC Directive 2004/104/EC, Annex I, 2.1.12.
Any equipment (or part of an ESA) which has a primary function of radio transmission and/or reception
according to the ITU Radio Regulations are excluded from the scope of this publication.
BS EN 50498:2010 covers the frequency range 9 kHz to 400 GHz. To date, it specifies limits and
methods of measurement for conducted and radiated disturbances from ESAs in the frequency range
30 MHz to 1 GHz and immunity requirements for conducted transients. The assessment of an ESA
needs to be performed only in the frequency ranges where limits are defined.
The emission requirements have been selected so as to ensure that disturbances generated by ESAs
operating normally do not exceed a level that could prevent the vehicle or apparatus external to the
vehicle from operating as intended. Fault conditions are not taken into account. Not all disturbance
phenomena have been included for testing purposes in this standard but only those considered as
relevant for the equipment covered by this standard.
As ESAs covered by this standard are not related to immunity-related function, only the following
electromagnetic disturbance phenomena are evaluated:
- broadband and narrowband radiated electromagnetic disturbances;
- conducted transient disturbances;
- conducted transient immunity.
Accessories that are not connected directly to the vehicle harness, but only via a special interface are normally excluded from vehicular EMC requirements.
