What is the EN50498 Standard?

For automotive products that do not fall within the scope of E-mark regulations, CE certification may be applicable under the EN 50498:2010 standard. EN50498, as a harmonized EN standard, provides a form of certification based on the CE self-declaration method.

Which types of products does it apply to?

It applies to products defined under clause 3.2.9 of Annex I of the 2004/104/EC Automotive EMC Directive. Examples include: in-vehicle chargers, car refrigerators, heaters, in-car audiovisual entertainment devices, FM transmitters used in vehicles, etc.

What if the product includes wireless communication functions?

If the product contains wireless communication features, the RED (Radio Equipment Directive) may also apply. In summary, EN50498 certification primarily targets electromagnetic interference within the vehicle, while CE certification has a broader focus on electromagnetic compatibility (EMC), including special considerations for automotive products.

What does the standard mainly test?

The European EN50498 standard sets emission and immunity limits for aftermarket electronic sub-assemblies (ESAs) used in vehicles and specifies the corresponding test methods. These devices must comply with the EMC requirements of Directive 2004/104/EC. The standard covers the frequency range from 9 kHz to 400 GHz, but evaluations are limited to disturbances generated by ESAs within defined frequency limits. The focus is on electromagnetic disturbances associated with ESAs that could affect the normal operation of the vehicle, including broadband and narrowband radiated emissions, conducted transient disturbances, and immunity.

How to determine whether CE or E-mark certification is needed?

It depends on whether the product falls under the scope of Directive 2004/104/EC. For example, products like in-vehicle phone chargers or smartphones, which are not specifically designed for automotive use, usually require CE certification under the red directive. EN50498 testing is only applicable when the product has an impact on driver control.

In summary, EN50498 certification primarily addresses internal vehicle interference, while CE certification more broadly considers the electromagnetic compatibility of products, including special cases for automotive devices.
