1. Introduction
1-1. About JQAJapan Quality Assurance Organization (JQA) was established as an incorporated foundation inaccordance with the Article 34 of the Civil Code in 1957, and it was then converted to a generalincorporated foundation in accordance with the Three Laws Related to Public Corporation System
Reform in April 1, 2011.
JQA is operated with operating revenues derived mainly from service charges, and it conducts businessas a third-party body for testing, inspection and certification while ensuring fairness and neutrality.
For an overview of JQA and certification, registration and testing, etc. performed by JQA, go to the
JQA website: https://www.jqa.jp

1-2. CMJ Registration Scheme
CMJ Registration Scheme is a scheme for prior assessment (testing and factory inspections) andregistration of components and materials to facilitate efficient and economical testing and certificationof electrical products. Even after registration, follow-up is conducted every year to continuously ensurecompliance. Using components or materials registered in this registration scheme will allow you to
confirm beforehand that corresponding components or materials conform to the technical standards ofElectrical Appliances and Material Safety Act, to reduce the quality control costs for the corresponding
components and materials necessary for manufacturers and importers of electrical products, and toutilize testing of components and materials in multiple certification bodies (registration inspection
bodies for Electrical Appliances and Material Safety Act and S-Mark certification bodies).
For further information, access to the Steering Council of Safety Certification for Electrical andElectronic Application and Parts of Japan (SCEA) website:
http://www.s-ninsho.com/index.html

1-3. JQA’s Certification Qualification for CMJ Registration

3-2. Testing of Components and Materials and Initial Factory Inspections(1) Testing of components and materials
Appendix 6 "Testing Standards of Components and Materials That Can be Registered by
Manufacturers and Importers of Components and Materials” shows testing standards forcomponents and materials that can be registered in JQA. JQA will conduct testing of components
and materials in accordance with the above table. If there is a difference between the above
standards and the applicable standards specified in the application form, JQA will give you
notification of it.
If non-conformities to applicable standards are found during testing of components and materials,
JQA will notify the applicant of the non-conformities. If the applicant receives a report ofnon-conformities, the applicant will verify the content and then take corresponding actions suchas taking corrective actions and withdrawing such application, etc. within a given period.
(2) Initial factory inspections
Factories that are not registered in CMJ Registration scheme must be assessed via the CENELEC
method (factory inspection method employed by European bodies) to determine whether products
are manufactured under an appropriate quality control system.
If the initial factory inspection reveals non-conformities to requirements, JQA will conduct
necessary inspections again after an application for improvement is made.
(3) Routine factory inspection
Routine factory inspection is conducted annually to verify that registered products
are adequately manufactured in compliance with the requirements of Optional
Registration System for components and Materials used in Electrical Appliances(CMJ). This is conducted by visiting only.
Details：Verification that the quality control system checked during the pre-license
factory inspection is maintained and that changes to the control system, if any, areadequate, and testing on selected samples of registered products.
If unsatisfactory findings that require corrective action are made during the inspection,
repeat inspection is conducted, if corrective action cannot be confirmed, registration may becancelled.
(3)-1 Sample selection for testing
During Routine Factory Inspections, samples are in principle selected randomly
from 10% of the number of registered series (rounded off) for flammability test.
In the case of registration including high-voltage dielectric strength test, samples
are selected for each series for high-voltage dielectric strength test.
If samples of registered series are not available during factory inspections, due tosmall production etc., they can be selected from samples for quality control test or instock, produced after the last factory inspection. Such samples must be kept in anenvironment that will not affect the quality of the wire.
(3)-2 Number of samples to be selected
For flammability test: Three samples at length of 50cm per series
For high-voltage dielectric strength test : One sample at length of 5m per series(Only for registration including high-voltage dielectric strength test)-4Japan Quality Assurance Organization

HOW TO CONDUCT FLAMMABILITY TEST ON EQUIPMENT WIRESUSED IN ELECTRIC APPLIANCES : EXPLANATIONSIntroduction
Discussions were made of testing methods to confirm the safety against flammability of built-in
jacketed wires (including tubes) used in electric appliances (television receivers, electronics-based toys
and other electronics-based playing appliance).
To examine this testing method, difference among representative methods to check flammability ofapparatus - use equipment wires, employed in various countries, are summarized in a “Comparative Listof Vertical Combustion Testing Standards for Equipment Wire Vertical Combustion Testing Standards”.
As for IEC, it is omitted this time because it its in the stage of unification of testing methods andconsideration of approval testing system. However, given the fact that IEC standards are serving as
international testing standards, it appears necessary for us to propose to IEC, not vice versa, ways to deal
with trends likely from now on, as well as this testing methods.
Detailed explanations are given below under each item.
1. Test Equipment
To increase reproducibility of test results, temperature humidity and atmospheric pressure are
specified. The specified figures were taken from the testing conditions for the temperate zone as
specified in IEC standards. Also, the brightness of the testing site and availability of exhaust, theformer necessary for identifying flame, and the latter for protecting testing staff, are not specified thistime, because it is difficult to set forth harmonized specifications.
2. Burner
Existing specifications are adopted because the Electrical Apparatus Safety Law TechnicalRequirements are based on various foreign standards. In addition, length of tube taken from UL and
CSA standards is specified.
In the meantime, specifying a testing flame by length could cause human errors to affect test results.
IEC is now considering an international unification of burner requirements in the hope of specifying
the test flame by gas and air flow. Once the unification is realized, this needs to be revised.

JQA2022-01970

3. Burner StandTo keep an angle between theburner and specimen and also
to repeat flame applications, aburner stand can be used.
For your reference, a burnerstand specified in UL standard
1581(1988) is illustrated right.

4. Expression of Dimensions
Flammability Test on Equipment Wires seems to have been developed by UL in the 1970s. When it
was employed by CSA, or introduced into the Electrical Apparatus Safety Law TechnicalRequirements, fractions were rounded in different way, thus producing gaps among the standards.
For this reason, with this testing method, those dimensions which do not appear to affect test results
were interpreted to be covered by such standards.
5. Standards for Absorbent Cotton
Technical Requirements of Electrical Apparatus Safety Low and UL standards alike employ
absorbent cotton for judging the spread of a fire caused by drops from a specimen. Considering
reproducibility of tests, it is recommended to use absorbent cotton, easily available at drug stores in
uniform quality, it must be left in a desiccator containing drying agents before use.
6. How to apply flame to broad-breadth specimens
At present, broad-breadth equipment wires used in apparatus, known by such names as flat cables andribbon cables, are becoming increasingly popular. Such being the situations, as a result of
examinations of how to apply flame to broad-breadth specimens, it was ruled that, in the case of abroad-breath specimen, a flame shall be applied to its broad-breath plane, because it is the direction
where the flame touches the specimen most, and because UL standard also require flame applicationfrom that direction.
7. Conductor inserted into tubing
Tubing needs to be tested allowing for the state of its actual use. But considering convenience andreproducibility of tests, a testing method to confirm flammability (UW-1) in UL standard 224“Extruded Insulating Tubing” was adopted.
