PSE certification

ItJapan's DENTORL law (electrical installations and material control law) stipulates that 498 products must enter the Japanese market for safety certification. Among them, 165 kinds of class a products should be certified by T-MARK, and 333 kinds of B products should be S-MARK certified.
According to the DENTORL method, 333 kinds of B products are divided into 7 parts:
Simple wiring casing and junction box
A simple single phase motor between 100V-300V
Household electric heating products
Household electric or video products
A civilian or household product using a light source
Household and commercial electronic products
Other 100V-300V electrical appliances
Since April 1, 2001, the electrical product control law (DENTORL) has been officially renamed the "Electrical Product Safety Act (DENAN)".
Different from the control of the stipulation of the previous laws and regulations, the new system will ensure the safety of products by non official organizations.
The original T signs and other signs were no longer used, and the penalties for importers were also strengthened.

Class A: designated electrical equipment and material products

Class B: other electrical equipment and material products
