EN 50498:2010

• Abstract:

  This European Standard 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. This European Standard 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.

Overview

EN 50498:2010 (CLC) is a European product-family standard for electromagnetic compatibility (EMC) of aftermarket electronic equipment installed in vehicles (Electrical/Electronic Sub‑Assemblies, ESAs). It is referenced by the Automotive EMC Directive 2004/104/EC and specifies limits and measurement methods for disturbance emissions and immunity relevant to ESAs that are not part of vehicle immunity‑related functions. The standard covers the electromagnetic spectrum 9 kHz to 400 GHz but, to date, defines specific measurement limits and methods principally in the 30 MHz to 1 GHz band and immunity tests for conducted transients.

Key topics and requirements

• Scope and exclusions
  • Applies to aftermarket ESAs (e.g., many infotainment or accessory modules) but excludes equipment whose primary function is radio transmission/reception (ITU Radio Regulations).
  • Accessories connected only via a special interface and not to the vehicle harness are normally excluded.
• Emission limits
  • Defines broadband (quasi‑peak) and narrowband (average) radiated disturbance limits for the 30 MHz–1 GHz range to prevent interference with the vehicle or external apparatus.
• Conducted disturbances
  • Specifies limits for conducted transient disturbances on power lines (including typical pulse amplitude limits for 12 V and 24 V vehicle systems).
• Immunity testing
  • Requires application of ISO 7637‑2 transients (pulses 1, 2a, 2b, 3a, 3b and 4) to supply lines and relevant interfaces; immunities are defined at specified test levels (level III) and functional status criteria (functional status D describes degraded operation until reset).
• Test process and reporting
  • Test plan must document ESA size, operating conditions, test facility and antenna types, frequency steps and exercising method.
  • Test reports must provide EUT identification, equipment used, set‑up, performance level, test data, observed effects, and parameters chosen where options exist.

Applications and who uses it

• Aftermarket ESA manufacturers (car alarms, navigation modules, vehicle sensors, non‑radio infotainment add‑ons) use EN 50498 to design for vehicle EMC compliance.
• EMC test laboratories use the standard to certify emissions and conducted immunity of ESAs referenced by the Automotive EMC Directive.
• Vehicle manufacturers (OEMs) and system integrators reference EN 50498 when evaluating compatibility of aftermarket products with vehicle electrical environments.
• Compliance engineers and certification bodies rely on its limits and test methods for CE/EC declarations and regulatory conformity.

Related standards

• ISO 7637‑2 (conducted transient test methods)
• EN 55013, EN 55020, EN 55022, EN 55024 (broadcast/ITE EMC standards)
• Automotive EMC Directive 2004/104/EC and Directive 2004/108/EC
