3.4.1 Evaluation of type testing result
If the results of all the test items are qualified, the results of type testing are regarded as “Pass”. If a few results of the test items are unqualified, but easily improved. It is allowed to deliver samples again and retest them. If any unqualified item appears again in the retest, the results of type testing will be regarded as “Fail”.
3.4.2 Evaluation of initial inspection of the factory
3.4.2.1 If there is no any non-conformity found during the whole inspection, the initial inspection of the factory is regarded as “Pass”. .
3.4.2.2 If there are slight non-conformities found which do not adversely affect the safety standard for certificate product, the factory shall take corrective actions within the specified duration. If the actions are regarded as effective by the inspection team, the initial inspection of the factory is regarded as “Pass”.
