MET Labs' extensive environmental and EMC capabilities can be put to good use for testing the performance and reliability of vehicle and tractor/trailer electronic components to climatic, dynamic, and electrical environments from natural and vehicle-induced sources, and to meet the homologation needs for this globally produced and marketed product.
MET can test to MIL-STD, SAE, IEC, DIN, ASTM and FCC standards and European Directive 95/54/EC (72/245/EEC) or ECE Regulation No.10.
Also, MET is an active member of OmniAir Certification Services and DoT Vehicle Awareness Device Program. Read about testing MET did as part of this Program in August 2011 and November 2011.

MET has a special competency in testing electric vehicles and EV charging stations. MET has tested both the North American and UK Tesla Roadster. Tests are in accordance with the European Automotive Directive, including Radiated Emissions and Immunity testing, and for SAE J551-5: Performance Methods of Measurement of Magnetic and Electric Field Strength from Electric Vehicles. The Tesla vehicle is a unique, completely-electric sports car.
Automotive Directive 95/54/EC
The Automotive Directive, 95/54/EC's scope includes all electrical and electronic equipment intended for use in vehicles. Any device which is solely within the scope of 95/54/EC is outside the scope of the generic EMC Directive (89/336/EEC). The only approval mark for automotive equipment that provides freedom of movement across Europe is the automotive type approval "e" mark.
MET can help electronic component manufacturers for the automotive industry obtain e-mark or E-mark approval according to the automotive directive 95/54/EC (72/245/EEC) or ECE Regulation No.10.
The approval process for e-mark or E-mark starts after the client provides relevant documentation and test samples for assessment and testing:
- MET carries out testing on samples in accordance with the Automotive Directive (Radiated immunity and Emissions).
- MET arranges the submission of all test reports/technical documentation to the Vehicle Certification Agency (VCA).
- VCA issues a type approval certificate, subject to a satisfactory review of the submitted documents and Conformity of Production (CoP) assessment.
- Client can affix e-mark on the product after receiving approval number from VCA.
Many of the auto manufacturers have developed EMC and electrical test specifications tailored to their test approach. MET has the systems and methods necessary to conduct these tests.
