In the certification of in-vehicle electronic products, the EN50498 standard holds an important position. With the development of automotive intelligence, the number of in-vehicle electronic devices is increasing, bringing convenience while also raising electromagnetic compatibility issues.
EN50498 is a standard formulated by the European Union for the electromagnetic compatibility (EMC) of in-vehicle electronic products, stipulating the CE self-declaration certification method. Manufacturers of products that meet the standard can self-declare, affix the CE mark, and sell in the European Union market. This standard ensures that in-vehicle products operate normally in complex electromagnetic environments and do not interfere with other devices.
EN50498 applies to products defined in Clause 3.2.9 of Annex I of the 2004/104/EC Automotive EMC Directive and the Annex of 2014/30/EU. It mainly includes detachable electronic products that do not affect driving safety.
For example, in-vehicle chargers, car refrigerators, and in-vehicle audiovisual entertainment devices must all comply with this standard to ensure they do not interfere with the normal operation of other automotive electronic devices.
If an in-vehicle product has wireless communication capabilities, it must also meet the electromagnetic compatibility requirements of the EN50498 standard and may need to undergo certification under the Radio Equipment Directive (RED). For example, in-vehicle Bluetooth devices and Wi-Fi routers must meet this certification to ensure effective use of wireless spectrum and electromagnetic compatibility.
EN50498 includes four key testing items:
- Broadband Radiated Emission Test
This test detects electromagnetic radiation from 30 MHz to 1000 MHz to ensure the product does not interfere with other devices.
- Narrowband Radiated Emission Test
This test detects radiation in specific frequency bands to prevent interference with automotive communication systems.
- Conducted Transient Emission Test
This test checks for transient interference generated by the product through power lines, ensuring it does not affect other devices.
- Conducted Transient Immunity Test
This test measures the product's resistance to interference from automotive power lines, ensuring it can recover normal operation after brief disturbances.
- Scope of Application
- CE Certification applies to nearly all products in the European Union market.
- E-mark Certification applies to vehicles and vehicle components.
- Regulatory Basis
- CE Certification is based on EU directives and harmonized standards.
- E-mark Certification is based on the regulations of the United Nations Economic Commission for Europe (UNECE).
- Certification Process Differences
- CE Certification: The company tests the product itself or via a laboratory, and after approval, affixes the CE mark.
- E-mark Certification: The company applies to a certification body, and after passing the test, affixes the E-mark.
The EN50498 standard provides an important guideline for the circulation of in-vehicle electronic products in the EU market. Understanding this standard and certification process is key to entering the EU market. We hope this article provides useful reference for in-vehicle electronic product certification, assisting manufacturers in achieving success in the international market.
