CMJ Registration Overview
Revised on July 27, 2018

CMJ Registration is a scheme for prior assessment (including testing and factoryinspections) and registration of components and materials to facilitate fast andcost-effective certification of end product electrical appliances.
In addition to initial assessments, annual follow-up inspections are utilized in theCMJ Registration Scheme to verify continuous conformity of registered componentsand materials.
CMJ Registration data is accepted by designated certification bodies and can beutilized to reduce lead times and testing of end products when obtaining themandatory PSE mark and voluntary S-mark for electrical product safety in Japan.
This allows makers with CMJ-registered components and materials to gain acompetitive edge when end product manufacturers select suppliers.
If you are interested in making use of the many competitive advantages offered by
CMJ Registration, please contact JET or JQA, which are the only CMJ Registration
Bodies in Japan (contact details are on the final page).

1. Advantages of CMJ-Registered Components and Materials(1) Improved marketability
Appliance makers prefer to use CMJ-registered components and materials in theirproducts for faster and cheaper end product certification. As such, CMJ
registration offers a substantial advantage in improving the marketability of yourcomponents and materials.
(2) Evidence of conformity to standards
All major components and materials test standards are covered by the CMJ
registration system. CMJ Registration can be used as evidence that components
and materials are safe and conform to standards.
(3) Eliminate submission of test samples and technical documents

1／4

For certification of end products which incorporate non-CMJ-registeredcomponents and materials, test samples and technical documentation for eachcomponent must be submitted for evaluation.
If components and materials have obtained CMJ registration in advance, thesesubmissions can be omitted.

3. CMJ Mark
CMJ-registered components and materials can display the CMJ mark.

CMJorFor insulated wires for appliances, the F mark for flame retardancy testing and the Kmark for resistance to electric strength testing can be marked on the sheath. TheCMJ mark can also be used instead of the F mark.
F mark:-F-K mark:-K-

4. Fast and Cost-Effective CMJ Registration
The CMJ registration process can be streamlined to reduce costs and lead times bymaking use of the options below.
(1) Utilizing IECEE-CB CB Test Certificates
Lead times and costs for testing can be reduced by submitting applicable
IECEE CB Test Certificates.
(2) Utilizing factory inspection data for overseas schemes
CMJ Registration Bodies which already conduct inspections for overseas
schemes at a customer’s factory location can utilize data from those inspections
to reduce the burden for the manufacturer.
Conversely, for overseas manufacturers, CMJ Registration Bodies’ overseas

partners may be eligible to conduct CMJ inspections locally. Please inquire fordetails.
(3) On-site testing by CMJ Registration Bodies
When the applicant’s testing facilities are suitable, CMJ Registration Bodies
can conduct on-site testing, resulting in reduced cost and lead time.

5. Joint-Application for IECEE CB Test Certificates
Customers can jointly apply for an IECEE CB Test Certificate when CMJ testing is
conducted pursuant to international standards (i.e. Appended Table 12 of the“Interpretation of the Ministerial Ordinance specifying technical standards of theDENAN Law”). IECEE CB Test Certificates can be utilized by any National
Certification Body (NCB) which is a member of the IECEE CB Scheme.

CMJ：Stands for “Certification Management Council for Electrical & Electronic
Components and Materials of Japan”
The council was established in April 1990, being composed of 15 organizations such as academicexperts, manufacturer association, registration bodies (JET & JQA), etc, for smooth execution
and prevalence/promotion of CMJ Registration System.
Subcommittees are now investigating various subjects of components and materials to beregistered: material subcommittee, thermostat subcommittee, F mark subcommittee andelectronic component WG.
