  From April 1, 2001, Japan's "Electrical Product Control Law" (DENTOR) was officially renamed the "Electrical Product Safety Law" (DENAN), which is different from the control of the agreement provisions of the previous regulatory system. The new system will ensure the safety of products by unofficial organizations, which not only replaces the original T mark, but also strengthens penalties for importers.

Japan PSE certification requirements for switching power supply adapters(图1)

  PSE certification is a compulsory certification in Japan, just like my country's CCC certification. Japan has released two sets of compulsory certification product catalogs. Class A: The designated electrical equipment and material products must be certified by a third-party certification body licensed by the Ministry of Economy, Trade and Industry of Japan. According to the DENAN law, manufacturers are obliged to save test results and certificates, and the label must have a diamond-shaped PSE mark. Class B: Other electrical equipment and material products must be certified by a third-party certification agency licensed by the Ministry of Economy, Trade and Industry of Japan. According to the DENAN law, manufacturers are obliged to save test results and certificates, and the label must have a round PSE mark.

  For different products, PSE certification requirements are also different. Divided into circular PSE certification and diamond PSE certification. There is a difference between the two. Round PSE certification does not require factory inspection, only samples and product related technical information need to be sent to the certification body. The diamond PSE certification requires factory inspection and the process of domestic CCC application is the same. It requires factory inspection, the cycle is long, and the cost is not low. Specific institutions can issue certificates. The round shape has a short time, does not require a factory audit, and is cheap, and the testing agency can issue a certificate by itself.

  1. Introduction to PSE certification

  Japan’s newly promulgated "Electrical Appliances and Material Safety Regulations" that replace the original electrical appliance ban law are very complicated. Take mobile phone chargers as an example: mobile phone chargers belong to category A products according to the regulations, and category A products must be authorized and approved by the Japanese government. Testing is carried out in a laboratory managed by METI. Such laboratories such as JQA, LET, UL Apex, non-Japanese laboratories such as UL are also authorized laboratories for this type of products (according to battery chargers and AC adapters). Therefore, companies applying for PSE certification should first choose a Japanese authorized laboratory and obtain a test report issued by the laboratory to prove that the product meets Japanese technical requirements. Japan has two sets of technical requirements for battery chargers, customers can choose arbitrarily:

  1. It is a very traditional Japanese technical requirement

  2. It is a technical requirement that is consistent with IEC60950 2nd +A4. It is recommended that Chinese customers choose the second option. In this way, since both China and Japan are members of IECEE-CB, customers can first obtain a CB report from CQC in China, and then report to The above-mentioned laboratories in Japan applied for the CB report. If you use method 1, the CB report cannot be accepted. If the product is designed to meet the second method and designed to comply with the IEC60950 standard, all safety components of the primary circuit such as capacitors and thermal trips must comply with the international IEC standards. If the product is designed to meet the first method and to comply with the Japanese national standard, all these safety parts of the primary circuit must comply with the Japanese national standard. It should be noted that if option 1 is selected, the CB report will not be accepted. It is also not allowed to mix mode 1 and mode 2.

  About factory inspection Before issuing a certificate, the inspection agency will conduct a factory inspection on the manufacturer. After the testing and factory inspection meet the requirements, the PSE logo and the logo of the testing agency are allowed to be used on the battery charger. It is required to conduct 100% testing on the products produced, but different product testing items are different, usually high-voltage test and protective grounding continuity test. For the charger, the certificate is valid for 3 years. The regulations require Japanese purchasers to register and declare to Japan METI within one month after purchasing the goods, and must mark the purchaser's name or ID on the product for supervision and management in the future product sales process. According to the Product Material Safety Law, all responsibility for the safety of products imported into Japan is borne by Japanese importers. Therefore, importers must keep inspection reports and inspection records. Importers can also view inspection records through the internet.

  2. Electrical Appliance and Material Safety Law? Enforcement Ordinance (Enforcement Ordinance of Electrical Appliance and Material Safety Law)

  3. Electrical Appliance and Material Safety Law? Enforcement Regulations of Electrical Appliance and Material Safety Law

  4. Explanation on Type Classification (Explanation on Type Classification) MITI promulgated Technical Requirements (Technical Requirements by the Ministerial Ordinance of METI) The specific requirements of the inspection, the same parts as the CCEE or CCIB requirements can be exempted from review, and different parts require supplementary review.

  2. As a part of electrical equipment and material products, switching power supply adapters fall within the scope of 165 specific electrical appliances for category A products. Those that have been certified by a third-party certification agency licensed by the Ministry of Economy, Trade and Industry of Japan can obtain a certificate and mark on the label. Only power supplies with a diamond-shaped PSE logo are eligible to enter the Japanese market, and only then will they be allowed to be sold and used. The PSE-certified power adapter is a diamond-shaped mark.

  3. PSE issuance agency for compulsory products of PSE in Japan, JET and JQA in Japan. Institutions outside Japan, TUV Rheinland, CQC institutions in China and UL in the United States. The Ministry of Economy, Trade and Industry (METI) of Japan recently issued an announcement on the revision of the twelfth form of the attached table, adding new standards such as J62368-1 (H30). The new standard J62368-1 (H30) was released on July 2018. Effective on the 20th.

  From the effective date, the standard IEC 62368-1 (2014) and the CB report covering the Japanese national difference J62368-1 (H30) can be used to apply for the PSE certificate of the Japanese standard J62368-1 (H30).

  4. Product categories certified by Japan PSE:

  (1) The category scope of Japan PSE specific electrical appliance certification is divided into categories:

  Wires and cables, fuses, wiring appliances (electrical accessories, lighting appliances, etc.), current limiters, transformers, ballasts, electric heating appliances, electrical power application mechanical appliances (household appliances), electronic application mechanical appliances (high-frequency epilators) ), other AC electrical machinery and appliances (electrical insecticide, DC power supply device), and carrying engines;

  (2) The category scope of Japan's PSE non-specific electrical appliance certification is ten categories:

  Wires and cables, fuses, wiring appliances, transformers, ballasts, conduits, small AC motors, electric heating appliances, electric power application machinery (paper shredders), light source application machinery (projectors, copies), electronics Applied mechanical appliances (video recorders, televisions), other AC electrical appliances, lithium battery storage batteries.
