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 2) 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 series of products are involved in the certification, at least one type/model sample shall be taken from each series for the product consistency check. The following major points shall be checked:
1) The nameplates, labels of products to be certified shall be identical with those indicated in the type testing reports.
2) The electric constructions of products to be certified shall be identical with those of the samples for type testing.
3) The critical components having significant effects on EMC performance shall be identical with those declared in type testing and confirmed by certification body.
All factories of the products to be certified shall be inspected.
The witness tests on site, if necessary, should be carried out to confirm EMC performance of the products during the factory inspection.
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 if needed.
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 manufactory.
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, reports submission after inspection, evaluation of certification results and approval of certificates, etc.
Normally, type testing takes 25 working days, (it is calculated from receiving the samples and fees; not including the time for corrective actions and retest of the nonconformities).
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 nonconformities.
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
4.5.1.1 The follow-up inspection shall normally be implemented at least once a year. The first follow-up inspection shall normally be implemented 12 months after the certificate being granted.

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 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 manufactories.
4.5.2 Contents of the follow-up inspection
The certification body shall implement the factory re-assessment in accordance with Requirements for Factory Quality Assurance Ability (see appendix 2).
