0 Introduction
This Rules is established based on the safety risk and certification risk of household gas
appliance products. It stipulates the basic principles and requirements for the
implementation of China Compulsory Certification for household gas appliance products.
This Rules can be used with other general rules issued by Certification and Accreditation
Administration (CNCA), such as “China Compulsory Certification Implementation
Rules - Manufacturing Enterprise Classification Management, Certification Mode
Selection and Determination”, “China Compulsory Certification Implementation Rules -
Utilization of Manufacturing Enterprise Testing Resource and Other Certification
Results”, “China Compulsory Certification Implementation Rules - Factory Quality
Assurance Capability Requirements”, and “China Compulsory Certification
Implementation Rules - Factory Inspection General Requirements”.
The certification body shall make principles for certification according to the general
implementation rules and this Rules and implement them accordingly.
Manufacturing enterprise shall ensure that their certified products are capable of
sustaining the compliance with the certification requirements.
1 Application scope
This Rules applies to domestic gas cooking appliances, domestic gas instantaneous water
heaters (household hot water gas instantaneous water heaters), and gas-fired heating and
hot water combi-boilers.
Due to the changes in the laws, regulations or related product standards, technology,
industry policies and other causes which may change the applicable scope, the
announcement released by CNCA shall be final and conclusive.
2 Certification standards
In principle, the current valid versions of above standards that are issued by the National
Standardization Administration shall be executed. When the above standards are revised,
it shall be implemented in accordance with the relevant documents issued by CNCA.
3 Certification modes
The basic certification mode of implementing the China Compulsory Certification for
household gas appliance products is:
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 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 specific program of certification implementation and INFORM
CLIENT.
6 Certification implementation
6.1 Product test
6.1.1 Product test plan
Certification body shall formulate the product test plan, after auditing the materials. And
INFORM the CLIENT.
The product test plan shall include sample requirements and quantities for product test,
test standard items, laboratory information, etc.
If the CLIENT submits a product test report that meets the requirements when proposing
the certification entrusting, the certification body shall accept it.
6.1.2 Sample requirements of product test
In general, for the samples for product test, CLIENT shall select representative samples
for testing according to the requirements of the certification body. When necessary,
certification body may adopt on-site sampling method to obtain the samples. In the
implementation detailed-rules, the certification body shall clearly clarify the relevant
requirements for certification product sample sending / sampling.
CLIENT shall guarantee that all the samples provided are consistent with actual products.
The certification body and / or laboratory shall review the authenticity of the samples
provided by the CLIENT. If the laboratory has doubts about the authenticity of the
sample, it shall explain the situation to the certification body and take corresponding
measures.
According to the regulations of relevant documents issued by CNCA, certification body
shall, in the certification implementation detailed-rules, specify the list of key
components used in the product and related requirements.
For key components within the scope of the compulsory product certificate purchased in
the territory, the manufacturing enterprise shall provide the compulsory product
certificate. For key components within the scope of non-compulsory product certificate,
in the certification implementation detailed-rules, the certification body shall specify the
conditions and specific requirements for the voluntary certification certificates or type
test / product test reports that can be accepted or recognized.
6.1.3 Items of product test
In principle, it shall include the compulsory safety items stipulated by the product
certification standards (for details, refer to the attachment).
When some test items in the standard are adjusted, it shall be implemented in accordance
with the relevant documents issued by CNCA.
6.1.4 Implementation of product test
In principle, product test shall be conducted in the laboratory designated by CNCA.
Laboratory shall conduct the product test to the samples, integrally record the whole test
and archive for retaining, so that the test process and results are traceable.
On the premise of not affecting the validity of the certification results, certification body
can 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. The laboratory shall ensure the authenticity, correctness and
traceability of the test results. Certification body shall specify the specific requirements
and procedure in certification implementation detailed-rules.
6.1.5 Product test report
Certification body shall specify a unified form of the product test report.
After the product test is completed, the laboratory shall, in time, provide the product test
reports to certification body and CLIENT. The test report shall contain the necessary
description of the product and certification-related information in the application unit.
CLIENT shall ensure that it is able to provide the complete and valid product test report
to certification body and laws enforcement authorities during the after-certification
supervision.
6.2 Initial factory inspection
The initial factory inspection is the on-site inspection and evaluation carried out by the
certification body to determine whether the quality assurance capability and product
consistency control capability of the manufacturing enterprise meet the certification
requirements. The initial factory inspection shall be carried out after the product has
passed the test; can also be carried out simultaneously with the product test if necessary.
According to “China Compulsory Certification Implementation Rules - Factory Quality
Assurance Capability Requirements” and “China Compulsory Certification
Implementation Rules - Factory Inspection General Requirements”, combined with the
product characteristics, the certification body shall formulate specific contents such as
initial factory inspection requirements and clarify them in the certification
implementation detailed-rules.
testing of manufacturing enterprises; and clarify them in the certification implementation
detailed-rules.
7.2 Factory on-site sampling test or inspection
7.2.1 Principles for factory on-site sampling test or inspection
