23、 party may audit this inspection. 8.3 Qualification inspection Laminates furnished under this specification shall be qualified. Qualification testing shall be performed to demonstrate the manufacturers ability to meet the requirements of this standard. Qualification testing shall be conducted at a l
24、aboratory compliant with IEC laboratory requirements. A list of the normal qualification tests can be found in Annex C.

25、nformance inspection The supplier shall operate a quality plan to ensure product conformance to this standard. Such a quality plan, when appropriate, should utilize statistical methods rather than lot-by-lot inspection. It is the responsibility of the supplier, based on the quality plan, to determin
26、e the frequency of test to ensure conforming products. In the absence of a quality plan or supporting data, the testing regime shall be as outlined in Annex C. A combination of the following techniques may be used to show compliance with the requirements which can be used to reduce the frequency of
27、testing. The data supporting the reduction of testing frequency shall be available for review upon request.
