Certification system and EMC requirements of foreign automotive electronic products

In the case of the European market, the current vehicle or automotive electronics products into the 1:3 European market must pass the ECE regulatory requirements and EU directive requirements. Radio interference suppression is an important part of the ECE automotive technical regulations structure system, in which the ECE part of the RIO, that is, the approval of the vehicle on the electromagnetic compatibility of the uniform provisions. In the EU directive, directive 72 / 245 / EC also made clear requirements for electromagnetic compatibility requirements.

At the same time, as the authentication system of support, standard system performance has tended to improve compatibility abroad automobile electronic products including electromagnetic area regulations, Association (Organization) and the national standards and enterprise standards. Electromagnetic compatibility of automotive electronic products require a notable feature that several brands of global automotive manufacturers have an important voice in the relevant association standards, they are combined with their own characteristics of automotive products enterprise standards, test items, test requirements more stringent, more in-depth research on detection technology, and often to their own enterprise standards as the procurement of automobile electronic products certification requirements. At present, the standard of electromagnetic compatibility of automotive electronic products is mainly represented by ISO and IEC standards. Compared with the requirements of the major automobile manufacturers, the technical content is mainly to study the representative, universal and mature testing items. And put forward a wide applicability of the limit value requirements. As a standard of association, it is often used as a reference or limit value in the various certification requirements. National standards, such as the European Union standards, the national standards of Japan, in order to equate the use of ISO and IEC standards, and for the certification requirements of countries. However, the United States and Europe to the requirements of the automotive electronic products regulations (instructions) often give power, such as ECE (European Economic Commission) regulations used for authentication, and proposed authentication requires conformity assessment requirements, namely the limit value. In addition, such as the use of EU (EU) directive, the United States DOT (U.S. Department of transportation) and EPA (U.S. Environmental Protection Agency) use of regulations, as a basis for certification and requirements.

The main test items and standards for automotive electronics include: radiation emission and transmission (CISPR 25); conducted transient transmission (ISO 7637-2); radiation immunity, conducted immunity (ISO 11452 series); static Discharge immunity (ISO 10605); conducted transient immunity (ISO 7637 series standard) and so on.

Foreign automotive electronics testing laboratory also has strict requirements, such as to become the three major US auto brand signing test laboratory, must pass the strict A2LA / AEMCLRP certification, although the domestic foreign laboratories have the relevant certification, but the China's local laboratories are still very few have the ability to pass AEMCLRP certification.
