SCOPE This specification addresses material durability for engine compartment and underbody plastic components that are not covered by other Ford performance specifications. 2. APPLICATION This specification addresses plastic components where no applica

3、ble Ford performance specification currently exists. This specification covers basic material durability and is comprised of two sections. Section A (para. 3.2) involves mainly preconditioning of parts that will go through full DV/PV testing, such as a new part. The preconditioned parts will then un

4、dergo the durability testing called out in the DVP. Section B (para. 3.3) involves basic material durability test requirements and should be used when full part validation is not required, such as a running change. Section B testing is performed on parts/test samples and should be used when no DVP d

5、urability testing is planned. This specification does not include fuel system components. 3. REQUIREMENTS Material specification requirements are to be used for initial qualification of materials. 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform t

6、o the Companys Standard Requirements for Production Materials (WSS-M99P1111-A). Data must be submitted to Materials Engineering upon completion of testing and before PPAP or SREA approval, see appendix A. 3.2 SECTION A, PRE-CONDITIONING OF PARTS Except for paragraph 3.2.5, the pass/fail criteria for

7、 this section are successfully passing the DV/PV testing. The sample size will be dependent on the DV/PV test plan. Subject the minimum number of parts (see table 1) to one cycle as described below: 3.2.1 Short Term Heat, Humidity and Cold Cycle High temperature will be dependent on location of the
