are considered as one certification unit:
Single material:
(1) Texture;
(2) Processing technique;
Laminated composite material:
(1) Texture and thickness of each layer;
(2) Processing technique;
(3) Connection mode among layers.
Multi-piece splicing material:
(1) Texture and structure of each piece (single or laminated composite);
(2) Processing technique;
(3) Connection mode among pieces.
For the interior materials of passenger cars, classification due to differences in application
materials, interior materials (parts) and usage parts shall also be considered.
The certification client shall propose certification entrustment based on the principle of unit
division. The same unit may contain multiple models of products. The same model refers
to products whose design has no impact on standard compliance.
The same product produced by the same producer and different production enterprises
(which shall have the same production process and the same key parts / raw materials
suppliers), or the same product produced by different producers and the same production
enterprise, shall be different application units. However, it can be type-tested on the
samples of one unit, and products produced by other production enterprises / producers
need to provide information for consistency verification.
3.2 Material submission for certification application
The certification client submits the certification entrustment to CQC through the Internet
(www.cqc.com.cn). The certification client must fill in the necessary enterprise information
and product information as required. CQC will review the application based on relevant
requirements, issue a notice of acceptance or rejection, or require the certification client to
make rectifications and re-submit the certification application.
After the application is accepted, the certification client shall provide relevant application
the Rules (for initial application and when there are changes);
(6) Factory inspection questionnaire (when application);
(7) Other required documents.
4. Type test
4.1 Type test scheme
For certification entrustments that require type test, after the application materials pass
the review, CQC will formulate a type test scheme in accordance with the principle of unit
division and certification standards and notify the certification client. The type test scheme
includes sample requirements for unit or unit combination sample delivery / sampling, test
standards and items, and laboratory information, etc. If there is only one model in the
application unit, samples of this model shall be submitted. When the same unit contains
multiple models / specifications, samples shall be selected from representative models /
specifications, and the selected samples shall cover the structural parameters of other
products and key parts / raw material producers as much as possible.
4.2 Type test sample requirements
4.2.1 Basic requirements
Type test samples shall be products produced by the production enterprise entrusted with
certification in accordance with the normal processing mode. The certification client shall
ensure that the samples it provides are consistent with the actual products produced, and
shall not borrow, rent or purchase samples for testing. CQC and / or laboratories shall
review the authenticity of samples provided by the certification client. If the laboratories
have doubts about the authenticity of the samples, they shall explain the situation to CQC
and handle it accordingly.
4.2.2 Requirements for sample submission
The certification client shall prepare samples in accordance with the requirements of the
type test scheme and submit them to the entrusted laboratory. If the certification client
requests it, CQC can also arrange for inspectors to conduct on-site sampling during the
factory inspection of production consistency in accordance with 5.3. Under this
circumstance, sample shall be carried out on the premise that the on-site inspection of
production consistency is concluded to be qualified, or if there are non-conformities, the
effectiveness of corrective measures needs to be verified in writing.
In principle, the production enterprise shall ensure that samples are sent to the entrusted
laboratory for type test within 20 days upon receiving the type test scheme. If the
certification client fails to send samples within the specified time due to special
circumstances, it must provide CQC with sufficient reasons for the delay in sending
samples.
4.2.3 Sample specifications and quantity for type test
4.2.3.1 Interior materials for vehicles
It shall be ensured that at least 5 specimens can be removed from the interior parts to be
submitted / sampled. If there are materials with different burning rates in different
directions, then, respectively take 5 (or more) specimens in each direction.
(1) For materials with the same design burning rate, the standard specimen is a
rectangle, with a length of 356 mm and a width of 100 mm. The thickness of the
specimen is the thickness of the part, but not more than 13 mm.
(2) If the shape and size of the interior parts are not sufficient to produce standard
specimens of the specified size, then, the following minimum size specimens shall be
ensured:
a) If the width of the interior parts is between 3 mm ~ 60 mm, the length shall be at
least 356 mm. Under this circumstance, the specimen shall be made as close to
the width of the interior parts as possible.
b) If the width of the interior parts is greater than 60 mm, the length shall be at least
138 mm.
4.2.3.2 Interior materials for passenger cars
The following minimum size requirements shall be satisfied:
a) Parts with a width ??? 100 mm and a length ??? 356 mm;
b) Parts of the same material, with a width ??? 100 mm, 138 mm ??? length < 356 mm,
and a cumulative length ??? 1 m used in the same part of the vehicle;
c) Parts of the same material, with 20 mm ??? width < 100 mm, length ??? 356 mm, and
a cumulative length ??? 2 m used in the same part of the vehicle.
Please see Table 5 in Appendix 5 for specific sample quantity, specification and size
requirements for sample submission / sampling.
4.2.3.3 Interior materials for specific types of vehicles
It shall be ensured that 3 (or more) specimens can be respectively cut from the interior
4.2.4 Relevant requirements for key parts / raw materials
For key parts / raw materials involved in the test scheme, if the producer or production
enterprise can provide a compulsory product certification certificate that complies with the
requirements or a voluntary certification certificate issued by a designated certification
institution, CQC will accept the certification results based on the review of the
corresponding certificate, and the test items of corresponding parts / raw materials can be
exempted. For specific parts / raw materials test items specified by CQC, valid test reports
issued by laboratories accredited in compliance with GB/T 27025 (ISO/IEC 17025) can
also be accepted.

5.1 Basic requirements
The producer or factory shall establish, implement and continuously maintain the
production consistency control system in accordance with the requirements of Appendix 2
of this Rules, so as to ensure that the certified products can continue to satisfy the
certification requirements. CQC will conduct compliance inspection on the factory?€?s
production consistency control system. The initial factory inspection is carried out in the
mode of production consistency control plan review + production consistency factory
on-site inspection (hereinafter referred to as factory on-site inspection).
Under normal circumstances, after passing the type test and production consistency
control plan review, the factory on-site inspection will be carried out. When necessary,
product type test and factory on-site inspection can also be simultaneously carried out.
In principle, the production consistency control plan review and factory on-site inspection
shall be completed within one year after passing the type test, otherwise, the product type
test shall be re-conducted.
Subsequent applications for the same type of products from the same enterprise are
exempted from the production consistency control plan review and factory on-site
inspection, and only post-certification supervision and inspection will be implemented.
5.2 Review of production consistency control plan
