2、requirements for a foam-in-place molded armrest assembly. 2. APPLICATION This specification was released originally for automotive door or seat armrests. This is not applicable for wrap around applications. Molded foam used in assemblies must also meet WSS-M15P20-B1/B2 requirements. The face materia

3、ls must meet the requirements of material specifications (eg M1F, M2F, M1H) and the appropriate Performance Specification 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materia

4、ls (WSS-M99P1111-A). 3.2 SAMPLE SELECTION Testing must be conducted on part at each prototype and production build phase unless specified otherwise by Ford Engineering. See Table 1 for DV/PV testing. 3.3 APPEARANCE (FLTM BI 109-01) The color, pattern, and finish shall match the approved Design Cente

5、r master sample, or shall be as specified on the engineering drawing. 3.4 CONSTRUCTION The parts consist of face/cover material laminated to foam, which are cut and sewn to the desired shape and injected with foam.

10、nd after the tests as demonstrated. Tactually/visually: The assembly shall not become tacky, lose surface-grain definition, or exhibit surface-color change; no wrinkling, distortion, blistering, delamination, blushing, hazing, milking, staining, or other objectionable visual appearance. Functionally

11、: No expansion, shrinking, or warping that will interfere with normal functional operations. 3.6 FATIGUE TEST (FLTM BO 113-04, 2000 cycles) 3.6.1 Original 3.6.2 After exposure per para 3.5.2 3.6.3 After exposure per para 3.5.3 The cover material shall not delaminate from the foam and there shall be

12、no evidence of foam crumbling. There shall be no permanent deformation greater than 2 mm. Results of this test shall be determined by cutting a cross section of the armrest after fatigue flexing.
