With the widespread use of automotive electronic products, the problem of electromagnetic compatibility between electronic products is becoming more and more serious, directly related to the normal driving and safety performance of vehicles. In order to ensure the electromagnetic compatibility performance of automotive electronic products, 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 electronic products have been incorporated into the certification management system.

Taking the European market as an example, vehicles or automotive electronic products currently entering the 1:3 European market must pass ECE regulations and EU directives. The content of radio interference suppression is an important part of the ECE automotive technical regulations and structural system. Among them, the RIO part of the ECE regulations is the unified regulation on electromagnetic compatibility in vehicle approval. Among the EU directives, Directive 72/245/EC also specifies the electromagnetic compatibility requirements

The main testing items and standards related to automotive electronic products include: radiated emissions and conducted emissions (CISPR 25); conducted transient emissions (ISO 7637-2); radiated immunity, conducted immunity (ISO 11452 series of standards); Discharge immunity (ISO 10605); conducted transient immunity (ISO 7637 series standard), etc. There are also strict requirements for automotive electronic product testing laboratories abroad. If you want to become a contract testing laboratory for the three major automobile brands in the United States, you must pass the strict A2LA/AEMCLRP certification. China's local laboratories currently have little ability to pass AEMCLRP certification.
