China Compulsory Certification Implementation Detailed-
Rules - Low voltage electrical components
0 Terms and definitions
Testing at Manufacturers Premises (TMP method for short)
Engineers from a qualified designated laboratory sent by a designated certification body
use the testing equipment of the factory laboratory for testing; the factory shall send
testing personnel to assist. The test report shall be reviewed and approved by the
relevant designated laboratory.
Witnessed Manufacturer’s Testing (WMT Method)
Engineers from designated laboratories dispatched by designated certification bodies
witness the factory laboratory testing conditions; the factory laboratory completes all
tests using its own equipment or submits the certification body's testing plan for the
factory, witnessing part of the testing conditions and testing items. Factory laboratory
testing personnel are responsible for issuing original records and drafting the testing
report in the prescribed format together with the witnessing designated laboratory
engineer. The testing report is reviewed and approved by the relevant designated
laboratory.
1. Scope of application
The Detailed-Rules for Low-voltage electrical components (hereinafter referred to as
the Detailed-Rules) are compiled, in accordance with the requirements of the
"Implementation Rules for Compulsory Product Certification Low-voltage apparatus
Low-voltage components” (CNCA-C03-02:2024) (hereinafter referred to as the
Implementation Rules) as a supporting document for the certification implementation
rules, which is used together with the implementation rules.
The scope of products and certification basis applicable to this Detailed-Rules shall be
consistent with the relevant provisions in the implementation rules; they shall be
adjusted in accordance with the announcements on catalog definition and catalog
adjustment, as issued by the National Certification and Accreditation Administration
(hereinafter referred to as the NCAA).
CQC formulates and publishes this Detailed-Rules in accordance with the provisions
of the certification implementation rules, based on the principles of maintaining the
effectiveness of product certification, improving product quality, serving certified
(3) Laboratory information (when testing is required), including laboratory address,
contact person and other information;
(4) The required certification process and time limit;
(5) The estimated certification fee or charging criteria;
(6) The responsibility division of the certification parties in each link of the
certification implementation;
(7) The contact information of relevant CQC staff;
(8) Other matters that need to be explained.
For applications that require testing, the certification client shall submit the relevant
materials to the corresponding laboratory. After completing the preliminary review of
the materials, CQC will determine the test plan and notify the certification client; for
applications that do not require testing, the certification client shall submit the relevant
materials to CQC.
5.2 Certification entrustment information
After the application is accepted, the certification client shall provide relevant
certification entrustment information and technical materials to CQC and/or the
laboratory in accordance with the requirements of the certification scheme, which shall
include:
(1) Certification application (signed by the authorized signatory and stamped with
the company seal);
(2) Registration certificate of the certification client, manufacturer, production
enterprise (such as business license, etc.);
(3) Factory inspection questionnaire (applicable to situations where factory
inspection is required);
(4) Relevant agreements or contracts signed between the certification client,
manufacturer and production enterprise;
(5) Product description information, mainly including: technical parameters,
structure, model description, list of key components and/or materials, electrical
schematics (if necessary), general assembly drawings (if necessary), differences
between products of different specifications contained in the same certification
unit, etc. (fill in according to the fixed format file provided by CQC);
(6) For change applications, supporting documents of relevant change items;
samples and fill in the sample receipt to CQC. If the laboratory has doubts about the
authenticity of the samples, it shall explain the situation to CQC and make
corresponding treatment.
For key components and materials within the scope of compulsory product certification
purchased domestically, the manufacturer shall provide a compulsory product
certification certificate.
6.1.3 Type test inspection items
Same as implementation rules 6.1.3. Special circumstances shall be implemented in
accordance with the resolution of the TC06 expert group of the National Certification
and Accreditation Administration. Specific inspection items are shown in Appendix 3
of this Detailed-Rules.
6.1.4 Implementation of type test
Type test time generally does not exceed 40 working days (calculated from the receipt
of samples and/or inspection fees that meet the test conditions; it does not include the
time taken by the enterprise to make rectifications and retests due to unqualified
inspection items). When the key components of the whole machine shall be subjected
to random tests, the time required for the test exceeds the test time of the whole machine;
the type test time is calculated according to the longest test time of the safety
components.
When some of the type test items are unqualified, the laboratory shall notify the
certification client in an appropriate manner within 1 working day; report the relevant
situation to the CQC. In principle, rectificati...
