Automobile material & components

        The integration of China's automobile industry into the global supply chain is the general trend of industrial development. At the same time, how to economically and environmentally dispose of end-of-life vehicles and promote the sustainable development of the automobile industry has become the focus of the world's automobile industry. Therefore, auto manufacturers and their parts suppliers must be able to manage the material composition of auto parts produced by them, as well as the release of hazardous substances in the environment and human health.

1.VOC detection:

VOCs (Volatile Organic Compounds) are important reasons that affect the air quality in the vehicle, and also endanger the health of the drivers and passengers in the vehicle. In order to reduce the impact of VOCs on the environment and the health hazards to drivers and passengers, more and more automobile manufacturers have started to reduce the emission of VOCs in vehicles from the source, and have established technical specifications and quality monitoring for automotive interior trim, interior accessories and auxiliary materials. Amber has advanced analysis equipment and professional VOC technical experts, who can perform VOC test on the whole vehicle, parts and materials.

2.ELV detection

On October 24, 2000, the European Union formally promulgated the ELV Directive 2000/53/EC on Abandoned Vehicles. The EU member states had transformed this regulation into their national laws before April 21, 2002. The scope of the Directive covers automobiles, auto wastes, auto parts and materials.

ELV main requirements:

Limit the content and use of harmful substances in all automobile parts and materials

■ Reduce the use of hazardous substances in the design process of vehicles

■ After July 1, 2003, the vehicles put on the market shall be free of Hg, Cd, Pb, Cr (VI), and the limit of prohibited components in all components and materials (except those specified in the exemption regulations)

■ Cadmium (Cd) ≤ 100ppm (0.01%)

■ Mercury (Hg) ≤ 1000ppm (0.1%)

■ Lead (Pb) ≤ 1000ppm (0.1%)

■ Hexavalent chromium (CrVI) ≤ 1000ppm (0.1%)

■ PBB PBBs ≤ 1000ppm (0.1%)

■ PBDE PBDE ≤ 1000ppm (0.1%)
