Introduction of “CMJ RegisteredComponents and Materials” (Revision)
July, 2018
JET-Japan Electrical Safety & Environment Technology Laboratories
JQA-Japan Quality Assurance Organization
CMJ Registration System is the system in which components and materials forelectrical appliances are evaluated (through testing and factory inspection) andregistered in advance for economical and efficient certification of the appliances.
Registration is valid successively through annual follow-up for the conformity.
By choosing components and materials registered in this system, conformity of whichto the technical requirements of “Electrical Appliance and Material Safety Law”
(hereinafter referred to as “Den-an Law”) has been already confirmed, you can reduce
their quality control cost. Also you can have the advantage of saving time and cost for
testing of your appliances incorporating them, since certification bodies (Registeredconformity assessment bodies under Den-an Law and “S” Mark certification bodies)
can use the data of the registration of these components and materials when theappliances are tested for conformity assessment.
In CMJ Registration System, wide variety of components and plastic materials areregistered and their list is available at the following websites.
JET: http://www.jet.or.jp/jetdb
JQA: http://www.jqa.jp/service_list/safety/service/voluntary/cmj/search.html
We would like to suggest that you adopt CMJ registered components and materials
for your electrical appliances so that you will have the advantages as shown below.
Note: In this document, according to revision of technical requirements under Den-an
Law implemented on Jan. 1, 2014 former “Paragraph 1” and “Paragraph 2” arerevised to “Appendix No.4 or 8” and “Appendix No.12” respectively.

1. Advantages of adopting CMJ registered components and materials(1) No need to submit components and materials
For conformity assessment of electrical appliances, certification bodies usually
request you to submit components and materials used in them for separate
testing. If you use CMJ registered components and materials, you will be
exempted from this burden.
(2) Reducing test period
If you use CMJ registered components and materials, the overall test period ofyour appliances will be shortened since these components and materials will
not be tested.
(3) Reducing test cost
If you use CMJ registered components and materials, test cost will be reduced
since these components and materials will not be tested.
(4) Reducing technical documents to be submitted
If you use CMJ registered components and materials, it is not necessary tosubmit various technical documents on them for testing of your appliances. All
you are requested to do is to submit the copy of Registration Certificate andsimple information on the way they are used (within the scope of registration).

CMJ：
Abbreviation of “Certification Management Council for Electrical & ElectronicComponents and Materials of Japan”
The council was established in April 1990, being composed of 15 organizations
such as academic experts, 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 andmaterials to be registered: material subcommittee, thermostat subcommittee, Fmark subcommittee and electronic component WG.
