3) Description of the difference between the different model/type of products in the same application unit.
4) Other necessary documents.
4.2 Type testing
4.2.1 Sample delivery for type testing
4.2.1.1 The principles of sample delivery for type testing
The representative samples from the units of application for certification shall be selected and supplied for type testing. According to requirements, samples of other products covered by the application unit should be supplied for additional testing on differences.
4.2.1.2 Samples quantity/amount requirements
The applicants shall take responsibility of sample delivery for type testing in accordance with the requirements of the certification body and be responsible for them.
The quantities of samples shall be according to the requirements of appendix 3 and those for components tested accompanying the appliances shall be according to the requirements of appendix 4.
4.2.1.3 Handle of samples and relating documents after type testing

The test items for safety shall include all appropriate items specified in standards.
Test items for EMC
a. 0.15MHz~30MHz radio continuous disturbance voltage (GB4343-1995)
b. 30MHz~300MHz radio continuous disturbance power (GB4343-1995)
c. 0.15MHz~30MHz radio discontinuous disturbance voltage (GB4343-1995)
d. Limits for the harmonic current emissions (GB17625.1-1998)
4.2.2.3 Test methods
The type testing shall be carried out according to the methods specified and/or referred in the standards.
4.3 Initial inspection of the factory
4.3.1 Contents of the inspection
The contents of factory inspection shall include the factory quality assurance ability assessment and the products consistency check.
4.3.1.1 Assessment of factory quality assurance ability.
The inspector assigned by the certification body shall carry out the factory quality assurance capability assessment according to the Requirements for Factory Quality Assurance Ability (see appendix 6) and the additional inspection requirements stipulated by CNCA.
4.3.1.2 Check of consistency of the product
The consistency of the product applying for certification shall be checked on the site of production. If more than one application unit are involved in the certification, at least one type/model sample shall be taken from each unit for the product consistency check. The following major points shall be checked:
1) The name of product, type/model and specification on the nameplates and packages of products to be certified shall be identical with those indicated in the type testing reports.
2) The constructions of products to be certified (mainly constructions in terms of safety and EMC performance) shall be identical with those of the samples for type testing.
3) The critical components in terms of safety and components having significant influences on EMC shall be identical with those declared in type testing and confirmed by certification body.
The witness tests on site, if necessary, should be carried out to confirm safety and EMC performance of the products during the factory inspection.
4.3.1.3 Inspection scope
All the products to be certified and processing premises shall be covered for inspection of factory quality assurance ability and of consistency of the products.
4.3.2 Timing of factory inspection
Normally, the initial inspection should be implemented after the sample has passed the type testing. The type testing and factory inspection can be implemented at the same time in special cases.
The duration of factory inspection shall be determined by the amounts of application units of products to be certified and with the consideration of the scale of the factory. It will normally take about 1 to 4 man-day for each processing premises.
4.4 Evaluation of certification results and approval of certification
4.4.1 Evaluation of certification results and approval of certification
The certification body shall be responsible for a general evaluation of the results of type testing and factory inspection and for issuing the certificates to the applicants for the conformed products. One certificate shall be issued for one application unit. The application of the certificates shall comply with the requirements for Regulations for Compulsory Product Certification.
4.4.2 Time frame
Time frame for certification means the working days from the acceptance of complete application till the issuance of the certificates, which includes the time of type testing, factory inspection, reports submission after inspection, evaluation of certification results and approval of certificates, etc.
Normally, type testing takes 30 working days, not including the time for corrective actions and retest of the non-conformity item(s). If the components are required to be tested and the required time exceeds that of appliances, the time of type testing should be calculated according to the longest test time of the component, counting upon the receipt of the samples and testing fees.
The inspection reports should be submitted within 5 working days after the inspection. It will be counted from the day when the inspectors complete the inspection and receive from the factory the corrective action reports on non-conformities satisfying the requirements.
Evaluating certification results and approving the certificates shall normally be completed within 5 working days.
4.5 Follow-up inspection
4.5.1 The frequency of follow-up inspection
The follow-up inspection shall normally be implemented at least once per year. The first follow-up inspection shall normally be implemented 12 months after the certificate being granted.
The frequency of inspection should be increased in any of the following cases:
1) The certified product has serious quality problem, or is complained by clients, which has been verified to be the responsibility of the certificate holder.
2) The certification body doubts the conformity of the certified product against the requirements of safety and EMC standards with sufficient reasons.
3) Sufficient information indicates that the conformity or the consistency of certified products might be affected due to the changes in organization structure, production condition and the quality system of the manufacturer and/or factories.
4.5.2 Contents of the follow-up inspection
The model of follow-up inspection: re-assessment of factory quality assurance ability + check of consistency of products certified, and if necessary, samples may be taken and tested at the testing laboratories.
The certification body shall implement the factory re-assessment in accordance with Requirements for Factory Quality Assurance Ability (see appendix 6). The items 3, 4, 5 and 9 specified in Requirements for Factory Quality Assurance Ability must be assessed for follow-up inspection and the rest items may be selected. All the items of the Requirements shall be covered at least every four years.
The duration for follow-up inspection shall be determined by the amounts of units of certified products with appropriate consideration of the production scale of the factory. It will normally take about 1 to 2 man-day.
4.5.3 Sampling & testing
If necessary, the certified products should be sampled and tested. The samples shall be taken randomly from the qualified products of the factory (including those from production line, stock and market). The designated testing bodies shall be responsible for testing. The methods and requirements for sampling shall be carried out according to the relevant specifications of the certification body.
The test items specified in the standards for certification can be applied to testing.
The certification body may carry out part or all of test items based on the degree of effects on the safety and/or EMC performance of the products.
4.5.4 Evaluation of follow-up inspection results
The certificates can be retained and the certification marks can be continuously used upon favorable inspection results. If there is any non-conformities found in the follow-up inspection, the corrective actions shall be taken within three months. Otherwise, the certificates will be withdrawn, the certification marks will be stopped using, and the relevant results will be announced.
5. Certificate
