Under the Japanese DENAN Law (Electrical Appliance and Material Safety Law), the PSE Mark is a mandatory safety mark for all electrical products sold and used in Japan. The purpose of the Law is to prevent hazards and disturbances resulting from electrical appliances.
The DENAN law regulates more than 450 products, which are classified as Specified Products (SPs) or Non-Specified Products (NSPs). All specified products require type testing and factory test equipment inspection conducted by a METI-authorized CAB.
Factory inspection is needed once per factory/ product category. Depending upon the product, the validity period of the certificate lasts from three to seven years. A re-evaluation testing of the product will be needed at the time of the renewal of the certificate.
CQC is a Registered Conformity Assessment Body (CAB) accredited by Japan’s Ministry of Economy, Trade and Industry (METI) to conduct product testing according to the DENAN Law and issue the PSE Mark.
