Japan PSE is mandatory safety certification, evidence of the electronic electrical products has passed the Japanese electrical product safety act (DENAN Law) or international IEC standard safety standard test.

Japan DENAN electrical and electronics products can be divided into two categories:
A specific electrical products (specified products), including 116 kinds of products；
B non - specified products, including 341 kinds of products.
Specific electrical product must be authorized by the Japanese ministry of economy of the third party certification body products and factory test equipment inspection, issuance of PSE certification, certification valid between 3 to 7 years, and labeled with PSE diamond in products.
Non specific electrical products is proved by means of self-examination and declare conformity of the product, and labeled with PSE circle on the product.

Japan's benchmark electrical product safety technology has two kinds:
（1）The province to item 1 benchmark, refers to the domestic technical standards;
（2）The province to item 1 benchmark, that is coordinated with the IEC standards.
Need to pay attention to, the province has standard item 1 and 2 benchmark is the province that established according to the standard system of independently, to pay attention to not be able to mix these two standards.

In the enforcement of rules don't watch the first 2 specifies the name of "electrical appliances", and as stipulated in the electrical products of the "type to distinguish". "Type" refers to the structure, material, or performance, "type to distinguish between" refers to the product safety aspects we confirmed by the structure of the scope of the same nature, material or performance, or a combination of all three. In a wide variety of products type, according to the nature of roughly the same elements and divided into different groups, this is the "type". Therefore, it is important to note that its varieties division and model may not be consistent with enterprise.

AGC can be done directly in the domestic circle PSE test and issue a report issued the certificates and the type of table, the test results have been obtained METI's approval.

lithium battery PSE

On January 18, 2008, the Japanese economy, trade and industry (METI) released the cabinet according to the electrical appliance and material safety law enacted law, a specific range of lithium ion battery has been included in the directory for electrical appliance and material safety products, since November 20, 2008, exports to Japan of the particular range of lithium ion battery, must conform to the requirements of the law about supplier compliance declarations, and listed on the relevant PSE marks must be paste

Specific range is: limited to the energy density of not less than 400 wh/L of secondary batteries, batteries, but does not include car with secondary lithium ion batteries, not including electric bike, medical equipment, industrial equipment used in secondary lithium ion battery, also does not include welding way or the battery in the similar way to fix battery installed on the equipment (cannot be easily shift), or those with special structure of the battery. According to the rules, most of the range of lithium batteries used in Mobile devices, such as Mobile Phone, Notebook, etc. These batteries and batteries PSE test standard are: JIS C 8714:2007.
