With the widespread use of automotive electronic products, electromagnetic compatibility issues between electronic products are becoming more and more serious, which directly relates to the normal driving and safety performance of vehicles. In order to ensure the electromagnetic compatibility performance of automotive electronic products, various countries and regions around the world have conducted extensive and in-depth research on the electromagnetic compatibility certification business of automotive electronic products.
In the United States, Japan, the European Union and other countries and regions, the electromagnetic compatibility requirements of automotive electronics have been incorporated into the certification management system.
Taking the European market as an example, vehicles or automotive electronics that currently enter the 1: 3 European market must pass ECE regulatory requirements and EU directive requirements. The content of radio interference suppression is an important part of the structure system of the ECE automotive technical regulations. The RIO part of the ECE regulations is the unified provisions on electromagnetic compatibility in vehicle approval. Among the EU directives, Directive 72/245 / EC also specifies the requirements for electromagnetic compatibility.
The main testing items and standards for automotive electronics include: radiated emissions and conducted emissions (CISPR 25); conducted transient emissions (ISO 7637-2); radiated immunity, conducted immunity (ISO 11452 series standards); Discharge immunity (ISO 10605); conducted transient immunity (ISO 7637 series standards), etc. Foreign countries also have strict requirements for automotive electronics testing laboratories. If they want to become the contracted testing laboratories of the three major American automobile brands, they must pass strict A2LA / AEMCLRP certification. At present, although there are related foreign laboratories in China that have passed the certification, China's domestic laboratories are rarely capable of passing AEMCLRP certification.
