Electrical Appliance and Material Safety Law (DENAN Law)

TÜV Rheinland Hong Kong Ltd. is a certified inspection body for the Electrical Appliance and Material Law (DENAN Law).The DENAN Law came into effect from April 1, 2002, replacing the Electrical Appliance and Material Control Law (DENTORI Law). This law requires inspection and certification by a certified inspection body for regulated items (specific electrical appliances). TÜV Rheinland Hong Kong, as an inspection body certified by the Ministry of Economy, Trade and Industry, provides the inspection and certification service for electrical appliances bound for the Japanese market. For electrical products that are not regulated, TÜV provides the testing and certification service of the safety mark for the Japanese market (S-mark and PSE-circle mark).

Product Inspection and Factory Inspection

TÜV Rheinland Hong Kong Ltd. provides a speedy and high-quality service for both product inspection and factory inspection that are required to issue a certificate of conformity.

Product Inspection

At a product inspection, both safety testing and RFI testing are necessary. TÜV Rheinland Hong Kong meets the technical standards specified in Clauses 2 of the Ministerial Ordinance. In particular for products bound for overseas, we can issue various certificates after just one test through our one-stop testing service.

Factory Inspection / Issue of Conformity Certificate

In order to issue a certificate of conformity, in addition to the product inspection, factory inspection is also required. Thanks to the network of TÜV Rheinland Group, we can provide efficient factory inspection service in China as well as all major countries over the world. For the regulated electrical appliances, a certificate of conformity will be issued based on the results of both product and factory inspections.

Registered Firms under the DENAN Law

The chart below shows the procedure for each firm to register its product under the DENAN Law.

Marks under the DENAN Law

Regulated electrical appliances and other electrical appliances are required to affix certain marks respectively. There are also cases where marking of PSE-circle or other marks, like S-mark, may be approved alternatively (e.g., parts). For details, please contact our local representative office near to your company.

PSE Mark - TÜV Rheinland Hong Kong

For specific electrical appliances, the name of the inspection body, which has issued the certificate, must be displayed near the mark. TÜV Rheinland provides the logo incorporating the TÜV logo mark for any product to which the conformity certificate was issued by TÜV Rheinland Hong Kong
