Certification

Certification of Components and Materials/CMJ Registration

Certification of Water Supply Apparatus

Articles 1 and Article 2 of Technical Requirements in the Ministerial Ordinance of the Electrical Appliance and Material Safety Law specify the requirements for components and materials that undergo repeated testing, and by registering the test results, they can be utilized to the maximum degree at the time of product testing. Accordingly, by selecting registered components, assembling manufacturers can save testing time and costs, while component manufacturers can emphasize the benefits when marketing to assembling manufacturers. When certifying components, they are utilized for the JET internal conformity assessment and inspection, and registered products at the Council for Electrical & Electronic Components and Materials of Japan ( hereinafter referred to as CMJ ) can be utilized by other domestic institutions, offering the benefit of a broad scope of applications. (In accordance with the intentions of the applicant, JET coordinates with other testing institutions, and a registered component can be given CMJ registration status upon approval from CMJ.)
