I. PSE Certification Introduction
PSE certification (ProductSafetyofElectricalAppliance&Materials) is a market access system implemented by the Japanese government for electrical and electronic products, and is an important element of Japan's Electrical Product Safety Law (referred to as "DENAN"). METI (Japan Ministry of Economy, Trade and Industry) management, METI does not directly issue certificates, but authorizes the cooperative manufacturer certification body to conduct product conformity assessment testing and issue certificates.
PSE certification is Japan's mandatory safety certification, to prove that electrical and electronic products have passed the Japanese Electrical and Material Safety Law (DENANLaw) or the international IEC standard safety standards testing. Japan's DENTORL law (Electrical Devices and Materials Control Law) stipulates that 498 kinds of products entering the Japanese market must pass safety certification. Among them, 165 kinds of A products should obtain the diamond-shaped PSE mark, 333 kinds of B products should obtain the round PSE mark.
Second, the scope of PSE certification products
So far there are 457 kinds of products in the scope of control of the Electrical Products Safety Law. Among them are likely to cause electric shock, fire and other accidents, the greater the danger of 116 kinds of products, classified as "specific electrical products - known as Class A electrical products", such as chargers, adapters; the rest of the less hazardous 341 kinds of products are classified as "non-specific electrical products - known as Class B electrical products", the majority of small and large home appliances The majority of small and large appliances, lighting products, lithium batteries "> lithium batteries are in category B.
Third, the application process
1. Customers prepare samples, applications and information submitted to BEST;
2. BESTONE testing laboratory for testing, if it is PSE round, then BESTONE testing issued a letter of declaration;
3. For PSE diamond shape, you also need to factory inspection;
4. After passing the test and factory inspection, the issuing agency to issue a PSE diamond-shaped certificate;
Fourth, which battery mandatory requirements to do PSE certification:
1. Energy density of more than 400Wh / L battery
2. Must be lithium-ion batteries">lithium-ion batteries
3. In addition to the lithium-ion batteries used in medical equipment, industrial equipment and automotive / motorcycle class
Five, lithium battery PSE certification test items
1, insulation resistance test
2, constant voltage continuous charging test
3、Vibration test
4、Battery casing test under high temperature environment

Six, lithium battery PSE certification process:
1. Fill out the application form,
2. Provide product information,
3. Send samples,
4. Test OK,
5. issued certificate / report cycle: about 1 month
