PSE certification in Japan

Date of issue:2020-05-13

PSE certification is a compulsory safety certification in Japan, which is used to prove that electrical and electronic products have passed the safety standard test of Denan law or international IEC standards. The dentorl law of Japan stipulates that 456 products must pass the safety certification when entering the Japanese market. Among them, 116 class a products should obtain diamond PSE mark, and 340 class B products should obtain round PSE mark.
 
Since April 1, 2001, "dentorl" has been officially renamed as "Electrical Product Safety Act (Denan)". Different from the conventional regulation system, the new system will ensure the safety of products by unofficial organizations
 
The difference between a circle and a diamond
 
All products in the rhombic PSE catalogue must pass the inspection of the third-party testing agency authorized by the Ministry of economy, industry and industry of Japan to obtain the test certificate when entering the Japanese market. If the products in the circular PSE catalogue enter the Japanese market, they must be tested by a third-party testing agency to obtain a certificate of conformity and confirm that they meet the technical standards of Japanese electrical appliances.

Se directory list
 
According to dentorl method, 340 kinds of class B products are divided into 7 parts
 
1) Simple wiring sleeve and junction box
 
2) simple single phase motor between 100V and 300V
 
3) household electric heating products
 
4) household electric or video game products
 
5) civil or household products using light sources
 
6) household and commercial electronic products
 
7) other electrical products between 100V and 300V
 
Class A: specified electrical equipment and material products
 
For example: AC adapter plugs multi tap
 
Class B: other electrical equipment and material products
 
Analysis of PSE certified products
 
01 plug and wire
 
For general electrical products, if the manufacturer's product is plug power cord, the plug, power cord body and connector must have diamond PSE logo. Size of plug
 
Must meet Japanese specifications. Because the surface area of the power line body is too small to mark the diamond PSE mark, it is usually replaced by "" symbol. PSE certificate of plug and power cord
 
It is valid for three years.
 
02 electric shaver
 
A. According to the power supply mode, electric shavers usually have three ways:
 
1. Common dry battery power supply
 
2. Sell battery charger for power supply
 
3. There is an integrated power plug for power supply.
 
B. For these three types of electric shavers, the Japanese government has the following three different management methods.
 
1. Ordinary dry battery powered shaver does not need to be pasted with PSE logo.
 
2. The battery charger powered by battery power supply unit must be pasted with PSE diamond logo. There should be PSE round mark on the shaver.
 
3. For the shaver with integrated power plug, there should be PSE round mark on the shaver.
 
It should be noted that if there is plug power cord in the shaver package, registration certification must be submitted to METI for plug power cord.

Certification scope of class a PSE specific electrical appliances
 
1) Wires and cables, fuses, wiring appliances (electrical accessories, lighting appliances, etc.), current limiter, transformer, ballast
 
2) Electric heating appliance, electric power appliance (household appliance), electronic appliance (high frequency hair remover)
 
3) Other AC electrical and mechanical appliances (electric shock insecticidal device, DC power supply device) and carrying engine must be certified by a third-party certification authority licensed by the Ministry of economy, trade and industry of Japan. According to Denan law, the manufacturer is obliged to keep the test results and the certification label must have the PSE mark of diamond

Scope of PSE certification for class B Japanese non specific electrical equipment
 
The products with PSE round mark certification in Japan, which belong to the "non specific electrical products" catalogue, must be tested by the laboratory approved by the Ministry of economy, industry and industry of Japan to confirm that they meet the technical standards of Japanese electrical products, and obtain the PSE certificate of qualified test report, then they can be pasted with PSE round mark on the products before they can be sold in the Japanese market.

Technical information of PSE certification in Japan
 
AC voltage: 100V
 
Working frequency: 50 / 60Hz
 
Japanese PSE certification cycle, certificate validity and factory inspection
 
Certification cycle: it varies according to the application standards and certification bodies. When the information is complete and the samples do not need to be rectified, usually 4-6 weeks with CB and 6-10 weeks without CB.
 
The validity period of the certificate: the diamond PSE certificate is valid for 3, 5 and 7 years (depending on the product). The round PSE certificate is usually self declared by the factory or the test report issued by the third party laboratory / certification authority.
 
Factory inspection: PSE will carry out a factory inspection (check whether there are relevant test instruments and their applicability) without follow-up inspection. Due to the different partners of each certification body in China, the organizations responsible for factory inspection in China are different. For example, JQA cooperates with China Import and export inspection and Quarantine Bureau.
 
Notice of PSE certification in Japan
 
There are two sets of technical requirements for battery charger in Japan. The applicant can choose the following methods at will:
 
The first is the very traditional Japanese technical requirements;
 
The second way is to meet the technical requirements of iec60950.
 
It is suggested that domestic applicants choose the second method. In this way, since both China and Japan are members of iecee-cb, the applicant can obtain CB report in CQC of China first, and then apply for transferring CB report to the laboratory mentioned above in Japan. If the first method is used, CB report cannot be accepted.
 
If the product is designed according to the second way, that is, according to iec60950 standard, all the safety parts of the preliminary circuit, such as capacitor and thermal release, shall comply with international IEC standard. If the product is designed according to the first way, that is, according to the Japanese national standard, all these safety parts of the primary circuit shall comply with the Japanese national standard. It should be noted that CB reports will not be accepted if the first option is selected. It is also not allowed to mix the first method with the second method.
 
Special note: although Japan is a member of CB, CB report can only be used as reference in general. If CB has done Japan's deviation test, CB can be directly transferred to certification, and the certification cycle is about 3 weeks.

Application for PSE mark conformity certificate
 
The following units may apply for the PSE mark conformity certificate:
 
A Japanese manufacturer; a Japanese importer; a designated foreign manufacturer by a Japanese importer
 
The notification supplier can only be the Japanese manufacturer / importer. After the supplier obtains the conformity certificate and pastes the PSE mark, METI will be deemed to bear the legal responsibility. Foreign manufacturers can not become notification suppliers, but must provide valid conformity certificate issued by Japanese Importers by qualified acab.
 
How to obtain PSE certification for Chinese manufacturers
 
Chinese manufacturers should first determine whether the products they apply for are within the scope of certification authorized by China Quality Certification Center (CQC). Since the current CQC authorization is based on the second method, the manufacturer must choose the second way to apply for PSE certification. After confirmation, the manufacturer can submit a written application to CQC and submit samples and technical data to PSE certification laboratory for type test. As both China and Japan are members of iecee-cb system, the test report can also be directly converted from CB report. After the completion of the test report, the applicant shall provide Japanese operation manual or assembly manual, product related structure and parts information, relevant information of testing equipment, factory quality inspection report (including 100% electrical strength test report of production line, operation inspection record, etc.) and accept factory inspection arranged by CQC. The PSE certificate can be obtained by factory inspection.
