3.3 Initial inspection of the factory
3.3.1 Timing of factory inspection
Generally, the initial factory inspection should be carried out after the application documents submitted meet the requirements.
The duration for the factory inspection is calculated based on the number of application units for certification, taking into considerations of the scale or size of the factory, normally 4~6 man-day for each manufacturing premise.
3.3.2 Contents of inspection
3.3.2.1 Assessment of factory quality assurance ability
The Requirements of Factory Quality Assurance Capability Assessment is of the basic requirements for initial factory inspection covered by this rule, which may also be carried out according to the specific requirements set by the certification body, if necessary.
(The inspectors assigned by the certification body shall carry out the factory quality assurance capability assessment according to the Requirements for Factory Quality Assurance Ability).
3.3.2.2 Check of consistency of product is to:
a)verify whether or not the critical raw/auxiliary materials used for product applied for certification are in consistency with those stated in the application documents;
b)verify whether or not the tests for product applied for certification are done in accordance with the required frequency;
c)test the randomly selected samples at premise for verification of safety characteristics .
3.3.2.3 All the products to be certified and the manufacturing/processing premises shall be covered for inspection of factory quality assurance ability and of consistency of the products
3.4 Evaluation of certification results and approval of certification
3.4.1 Evaluation of certification results
3.4.1.1 Sample Test
All the test items for safety characteristics shall comply with the requirements specified in the relevant standards. Should any one do not comply, certification shall be terminated. The applicant can reapply for certification after effectively taking corrective actions.
3.4.1.2 Initial Factory Inspection
The evaluation results are classified into 3 levels:
a)if there is no nonconformity found during the whole inspection process, the factory inspection shall be deemed as satisfactory;
b)if there are minor non-conformities found which do not adversely affect the safety characteristics of the product, the manufacturer shall take the necessary corrective measures in a specified interval. The factory inspection shall be deemed as satisfactory after the evidence submitted is verified by the inspection team for its effectiveness;
c)if there is a major nonconformity found or factory does not have the ability to produce the products which conform to relevant standards, the factory inspection shall be then terminated.
3.4.2 Approval of Certification
After the results of both factory inspection and sample test are evaluated to conform to the requirements, the certification body shall issue the certificate(s). The use of certification shall comply with the requirements specified in the Regulations for Compulsory Product Certification.
3.4.3 Time frame
The time frame for certification means the working days from the acceptance of application till issuance of the certificates, which includes the time of sample test, factory inspection, evaluation on certification results and approval of certificates as well as the preparation of the certificates.
It normally takes 30 working days for sample test, starting from the date of receiving the samples and 5 working days for submission of factory inspection report.
It will generally not exceed 5 working days for evaluation of certification results, approval and preparation of certificates.
3.5 Follow up inspection
3.5.1 The frequency of the follow up inspection
3.5.1.1 The follow up inspection shall normally be carried out at least once per year, starting from 12 months of receiving certificates.
3.5.1.2 The frequency of follow-up inspection should be increased if any of the following cases occurs:
a)when the certified product has serious quality problems or there is a customer complaint about the quality which has been confirmed to be the certificate holder’s responsibility;
b)when the certification body has some queries on the conformity of the certified product against the requirements of safety standards with sufficient reasons;
c)when there is sufficient information that indicates the conformity or the consistency of the certified product may be affected by the change of organizational structure, production condition and/or the quality management system of the factories/manufacturers.
3.5.2 Contents of the follow-up inspection
3.5.2.1 Model of the follow up inspection
The model of the follow-up inspection: re-assessment of factory quality assurance ability + check of consistency of products certified + sample test.
3.5.2.2 Reassessment for the factory quality assurance ability
The reassessment for factory quality assurance ability shall be carried out according to Requirements of Factory Quality Assurance Ability by the certification body. The time frame for such reassessment is calculated normally on 1~4 man-day per each manufacturing/processing premise.
The reassessment shall cover all the requirements set out in Requirements of Factory Quality Assurance Ability within 4 years, starting from the date of obtaining the certification. In the fifth year, an overall reassessment for the factory will be required according to Requirements of Factory Quality Assurance Ability. The scope of reassessment and the time frame arranged for such activity is the same as the initial factory inspection.

As described in sub-clause 3.3.2.2
3.5.2.4 Product sampling test
Within 4 years starting from the date of obtaining the certificates, the representative products from some of the certified units shall be selected for test for safety performances. In the fifth years, the representative products from each unit shall be selected for test for safety performances. The quantities and test items please refer to Appendix 3 and 4.
The span for test of all the certified units shall be 4 years.
3.5.3 Evaluation of the follow-up inspection results
The qualification for the certification and the use of certification marks can be retained for the positive results of the follow up inspection. Should there be any nonconformity found, the corrective actions shall be taken within three months. The certification will be withdrawn and the use of the certification marks be stopped if overdue. The notification of such withdrawal will be made public.
4 Maintenance and change of the certification
4.1 The validity of the certificate
The certificates for products covered by this Rule principally have no expiry date and their validity depends on the regular follow up inspection by the Certification Body to maintain the validity.
4.2 Change of the certification
4.2.1 Procedure for change
When changing the certified range of the product within the same unit, the certification holder shall first apply for such change and the Certification Body will review the consistency of the changed product with certified product and then verify the effectiveness of previous certification results on the changed product, to decide the need for additional test(s) or inspection based on the differences.
After approval, either a separate certificate can be issued or the original certificate can be replaced on the request of the certificate holder.
4.2.2 Requirements for sample
According to the procedure for change, the parameters/data for changed product are compared with the certified to decide the need for further test of product for which the test items are listed in Appendix 3, 4 and 5.
