This is a service for testing, inspection and certification based on a contract between a manufacturer and JET. Because earth leakage breakers and circuit protectors are critical components to ensure safety, JET performs not only the tests required by the Electrical Appliance and Material Safety Law but also stricter tests to verify their safety, quality and performance. A certified product is allowed to bear the certification mark to demonstrate the third-party certification. The mark helps users rely on the products.
