purposes is:
Mode 1: Type test + initial factory inspection + after-certification supervision
The basic steps of certification include:
a. Certification application.
b. Type test.
c. Initial factory inspection.
d. Evaluation and approval of certification results.
e. After-certification supervision.
Mode 2: Type test + after-certification supervision
The basic steps of certification include:
a. Certification application.
b. Type test.
c. Evaluation and approval of certification results.
d. After-certification supervision.
For manufacturers holding product certification certificates issued by CQC
(such as safety certification, energy-saving certification), Mode 2 can be used
for certification. Other manufacturers shall adopt Mode 1.
3. Certification application
3.1 Division of certification units
In principle, carry out certification unit division according to the type, structure,
material, rated connection capacity, rated insulation voltage, protection against
electric shock, maximum operating ambient temperature, protection against
water and solid matter ingress of clamps for connecting devices.
The connecting devices, of which the type, structure, material, protection
against electric shock, maximum operating ambient temperature, protection
against water and solid objects entering the clamps of the connecting device
are the same but the rated connection capacity and rated insulation voltage are
different, can be divided as the same unit.
Products from different production sites are regarded as different application
units. Products from different manufacturers are considered as different
application units. The type test of products with the same specification and
model can be carried out on samples from one factory.
3.2 Materials submitted for certification application
3.2.1 Application materials
a. Formal application form (print after filling in the application form online or
download a blank application form and fill in).
b. Factory inspection questionnaire (when applying for the first time).
c. Description of connecting devices for household and similar purposes
(CQC11-462195.01-2011).
3.2.2 Proof materials
4) 51~114 twisted connecting devices, and 27~72 coverage samples (the
specific quantity depends on the sample situation, and the sample is sent
according to the requirements of Table 101 in the standard);
5) 10 connecting box and enclosure type test samples, and 3 coverage
samples;
6) For connecting devices with flat quick-connect terminals, on the basis of
meeting the sample submission requirements in Articles 1~5, additional
samples containing at least 12 integral blade terminals shall be sent.
4.1.3 Disposal of samples and materials
After the test is completed and the test report is issued, the relevant materials
are kept by the testing agency, and the samples are disposed of in accordance
with the relevant CQC regulations.

The product inspection items are all applicable items specified in the standards
listed in 4.2.1. For connecting devices with flat quick-connect terminals,
relevant items shall be tested for integral inserts according to GB/T 17196-2017.
4.2.3 Test methods
Inspect according to the testing methods and/or standards stipulated and/or
quoted in the standards listed in 4.2.1.
4.2.4 Time limit of type test
Generally, it is 30 working days, counting from receipt of samples and
completion of confirmation. The time for rectification and re-inspection due to
failed test items is not included in the calculation.
4.2.5 Determination
The type test shall meet the requirements of product standards. When some of
the type test items fail, the applicant is allowed to make rectification. The
rectification shall be completed within the time limit specified by the certification
body (calculated from the date of notification of failure of the type test). If the
rectification is not completed on time, the applicant shall be deemed to have
given up the application. The applicant may also terminate the application
voluntarily.
If any one item does not meet the standard requirements after rectification, it is
determined that the certification unit product does not meet the certification
requirements.
4.2.6 Type test report
The testing agency designated by CQC tests the samples and issues a test
report in the specified format. After the certification is approved, the testing
agency is responsible for sending a test report to the applicant.
4.3 Requirements for critical components and parts
See Annex 2 "Product description of connecting devices for household and
similar purposes" for critical components and parts. To ensure the consistency
of certified products, when the technical parameters, specifications, models and
manufacturers of critical components and parts change, the certificate holder
shall submit a change application in time and send samples for testing. They
If the conclusion of the factory inspection is Not-PASS, the inspection team shall
report directly to CQC. If there are non-conformities in the factory inspection,
the factory shall complete the rectification within the specified period, and CQC
shall take appropriate measures to verify the results of the rectification. If the
rectification fails to be completed on time or is Not-Pass, the factory inspection
will fail.
6. Evaluation, approval and time limit of certification
results
6.1 Evaluation and approval of certification results
CQC organizes a comprehensive evaluation of the results of type test and
factory inspection. After passing the evaluation, the applicant is issued a
product certification certificate, and a certificate is issued for each certification
unit.
6.2 Time limit of certification
After the completion of type test and factory inspection, the applicant shall be
issued a certification certificate within 30 days if it meets the certification
requirements.
6.3 Certification termination
When the type test fails or the factory inspection fails, CQC makes a decision
of failure and terminates the certification. If the applicant wants to continue to
apply for certification after the certification is terminated, the applicant must re-
apply for certification.
7. After-certification supervision
7.1 Supervision-inspection time
7.1.1 Frequency of certification supervision-inspection
Generally, annual supervision shall be arranged within 12 months after the
initial factory inspection (for enterprises adopting certification Mode 2, annual
supervision can be arranged within 6 months after certification). The interval
between each annual supervisory inspection shall not exceed 12 months. If
Mode 2 is adopted to implement certification, the content of the first supervision-
inspection is the same as that of the initial factory inspection. CQC can adjust
the timing of supervision-inspection on an annual basis according to the actual
situation of product production. Increase the frequency of supervision if one of
the following occurs:
1) The certified product has serious quality problems or the user has
submitted a serious complaint, which have been verified that it is the
responsibility of the certificate holder;
2) When CQC has sufficient reasons to question the compliance of the
certified product with the certification standards;
3) When there is sufficient information to indicate that the conformity or
consistency of the product may be affected by changes in the organization,
production conditions, quality management system, etc. of the producer
or production factory.
7.1.2 Number of man-days of supervision-inspection (see Table 2)
7.2 Contents of supervision-inspection
CQC supervises and inspects factories according to CQC/F 001-2009 "CQC
Mark Certification Factory Quality Assurance Ability Requirements". Articles 3,
4, 5, 9 and the use of CQC marks and certification certificates are mandatory
items for each supervision-inspection.
The contents of the consistency inspection of certified products is basically the
same as the contents of the product consistency inspection during the initial
factory inspection.
Check the product quality inspection in accordance with Table 1 ?€?Factory quality
control testing requirements for certification of connecting devices for
household and similar purposes?€?.
7.3 Conclusion of supervision-inspection
The inspection team is responsible for reporting the conclusion of the
supervision-inspection. If the conclusion of the supervision-inspection is Not-
PASS, the inspection team shall report directly to CQC. If there are non-
conformities in the supervision-inspection, the factory shall complete the
rectification within the specified period, and CQC shall take appropriate
measures to verify the results of the rectification. If the rectification fails to be
completed on time or is Not-Pass, the supervision-inspection will fail.
7.4 Supervisory sampling inspection
When necessary, carry out supervisory sampling inspection on certified
products. Samples shall be randomly selected from qualified products
produced by the factory (including production lines, warehouses, markets).
Each production plant (site) must be sampled for each certificate. The sample
8.1.2.2 Evaluation and approval of changes
CQC evaluates the content of changes and the materials provided to determine
if changes can be made. If tests and/or factory inspections need to be
scheduled, changes can only be made after passing the tests and/or factory
inspections. In principle, the evaluation of changes shall be based on the
certified products that were subjected to type test originally. Tests and factory
inspections shall be carried out in accordance with the relevant CQC
regulations.
Approve changes to those that meet the requirements. If a new certificate is
issued, the serial number and approval date of the new certificate will remain
unchanged. Indicate the renewal date.
8.2 Extension of products covered by certification certificate
8.2.1 Extension procedures
If the certificate holder needs to increase the product certification scope that is
the same certification unit with the certified product, it shall start from the
certification application and explain the expansion requirements. CQC checks
the consistency of the extended products with the original certified products,
confirms the effectiveness of the original certification results on the extended
products, performs supplementary tests or factory inspections on differences
and/or extended scope, and issues a certification certificate separately or
renews the certification certificate according to the requiremen...
