The China National Accreditation Service for Conformity Assessment (CNAS) is a member of the Multilateral Mutual Recognition Agreement of the International Laboratory Accreditation Cooperation (ILAC) and the Asia-Pacific Laboratory Accreditation Cooperation Organization (APLAC). After being recognized by the organization, it marked the first in the refrigerator industry in China. Reports issued by RoHS Laboratories (Test Centers) will be recognized by the above-mentioned 116 member countries and regions of the organization.
RoHS is a mandatory standard set by the EU legislation. Its full name is "the directive on restricting the use of certain harmful components in electrical and electronic equipment." The standard strictly limits the content of six substances in lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers in electrical and electronic products, and it has focused on limiting the content of lead to no more than 0.1%.
The EU replaced the United States in 2004 and became China's first home appliance export market. Since then, Chinaâ€™s home appliance exports to the European Union have continued to grow strongly, and annual exports accounted for more than 23% of total exports for the same period. At the same time, it should be noted that the EU countries pay special attention to product safety and environmental protection. Therefore, green technology regulations and standards introduced in recent years have become increasingly stringent, which has caused a barrier effect on China's household electrical appliance enterprises exporting to the European Union. How to cross this green trade barrier has become a necessary hard work for Chinese home appliance companies.
With the completion of the China Refrigeration Industry RoHS Laboratory, China's home appliance industry will promote the upgrading of green technologies and provide a strong guarantee for Chinese home appliance companies to leapfrog the EU's green trade barriers.
