4、, and D-pillar moldings, hard instrument panels, instrument panel components and garnish molding. 2.1 LIMITATIONS Not applicable for painted or wrapped parts. 3. REQUIREMENTS 3.1 APPROVED SOURCES This specification is performance based and does not have approved sources. 3.2 CONDITIONING AND TEST CO
5、NDITIONS All test values are based on material conditioned for not less than 24 h prior to testing in a controlled environment of 23 +/- 2 C and 50 +/- 5% relative humidity. Testing of the material should occur in the conditioning environment or soon after removal. 3.3 PERFORMANCE CRITERIA Excluded

8、st), instrument clusters (WSS-M15P52-A) interior NVH components (WSS-M99P32-E1/latest) or whose performance is specified separately. 3.4 DV/PV TEST PLAN PEC/FEC/PV testing must be conducted in compliance with program milestones unless otherwise specified by Ford Engineering. See Table 1 and 2 for DV
9、/PV testing. Testing for mold-in-color components is detailed in Table 1 unless specified otherwise by Ford Engineering. Testing for non-visible components is detailed in Table 2 unless otherwise specified by Ford Engineering. Testing must be done on parts unless part geometry does not allow. If tha
10、t is the case, appropriate plaques with production grain and color can be used.
