requirements, specify the checklist of application materials in the implementation
detailed-rules (it shall at least include certification application form or contract, registration
certificates of the CLIENT / manufacturer / manufacturing enterprise, etc.).
CLIENT shall provide the required materials according to the requirements of application
material checklist in certification implementation detailed-rules. Certification body is
responsible for auditing, managing, preserving and keeping confidential of the relevant
materials, and shall inform the CLIENT of the auditing results.
5.3 Implementation arrangement
Certification body shall agree with the CLIENT on the relevant responsibilities and
arrangement of both parties in various aspects of certification implementation. And according
to the situation of manufacturing enterprise and classification management AND the
requirements of this Rules and certification implementation detailed-rules, DETERMINE the

formulate corresponding management procedures according to “China Compulsory
Certification Implementation Rules - Utilization of Manufacturing Enterprise Testing
Resource and Other Certification Results”. The designated laboratory sends testing personnel
to use the testing resources of the manufacturing enterprise to conduct test or witness test
according to the standard requirements. The designated laboratory shall issue the test report.

Certification body shall specify the specific requirements and procedure in certification
implementation detailed-rules.
7 After-certification supervision
After-certification supervision refers to the supervision carried out by the certification body
on the certified products and their manufacturing enterprises. The certification body shall, in
light of the classification management of the manufacturing enterprise and the actual situation,
specify the specific requirements for the selection of the method for after-certification
supervision in the certification implementation detailed-rules.

enterprise; to verify that the quality assurance capability of the manufacturing enterprise
continues to meet the certification requirements; ensure that the certified products continue to
meet the standard requirements and maintain the consistency with the product test samples.
The after-certification follow-up inspection shall be carried out in the way of not informing
the inspected party in advance when the manufacturing enterprise is in normal production. For
those products that are not continuously manufactured, CLIENT shall provide the relevant
production plan to certification body, so that the after-certification follow-up inspection can
be conducted in an effective way.
7.1.2 Content of after-certification follow-up inspection
In accordance with “China Compulsory Certification Implementation Rules - Factory Quality
Assurance Capability Requirements”, the certification body shall formulate specific content
such as the requirements for after-certification follow-up inspection, the requirements for
