5 vehicle emission testing As the most harmful vehicle emissions, exhaust purification problems in the auto industry has become one of the factors play a decisive role on the emission control more and more attention has been paid. Therefore, control the spread of pollutants in the exhaust, it was limited to the extent permitted, is the primary means of protecting the environment, the importance of environmental testing on the car also goes without saying.
6-car electronic equipment E / e Mark Certification E mark from the Economic Commission for Europe (Economic Commisssion of Europe, referred to as ECE) regulations promulgated by the current ECE 28 countries in Europe, in addition to EU member countries, including Eastern Europe, Southern Europe and other non-European countries. ECE members are usually willing to comply with ECE regulations to receive the test report and certificate. E signs the certificate is related to the product components and system components, there is no corresponding vehicle certification regulations, access to E logo certified products, is accepted by the market. E signs the certificate issuing body is the ECE member of the government departments, national certificate has a corresponding number.
