PSE Circular Certification: Category B Japanese Non-Specific Electrical Appliance PSE Certification Scope
Products certified with the Japanese circular PSE mark, belonging to the "Non-Specific Electrical Appliances" category, must undergo testing by a laboratory accredited by the Japanese Ministry of Economy, Trade and Industry (METI) to confirm compliance with Japanese electrical appliance technical standards and obtain a qualified test report and PSE certificate before the PSE circular mark can be affixed to the product, allowing it to be sold in the Japanese market.
