REQUIREMENTS3.1 QUALITY SYSTEM REQUIREMENTSMaterial suppliers and part producers must conform to QualitySystem Requirements, QS-9000. Material specification requirementsare to be used for initial qualification of materials. A C
5、ontrolPlan for ongoing production verification is required. This planmust be reviewed and approved by the relevant Ford Materialsactivity and/or Ford Supplier Technical Assistance (STA) prior toproduction parts submission. Appropriate statistical tools must beused to analyze process/product data and
6、 assure consistentprocessing of the materials.Part producers using this material in their products, must use Fordapproved materials and must conform to a process control plan whichhas been approved by STA and/or the relevant Materials Activity.3.2 INFRARED SPECTROPHOTOMETRY AND/OR THERMAL ANALYSISFo
