2、M15P26-D 1. SCOPE This specification defines the performance 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 m

3、ust also meet WSS-M15P20-B1/B2 requirements. The face materials must meet the requirements of material specifications (eg M1F, M2F, M1H) and the appropriate Performance Specification 3. REQUIREMENTS 3.1 APPROVED SOURCES This specification is performance based and does not have approved sources. 3.2

4、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 Center master sample, or shall

5、 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.

7、are, wiring, etc.) and assembled onto actual or representative production support foundations that include not only all attaching points but also any boundary conditions that may restrict movement, unless otherwise specified by the affected Materials Engineering Activity. The retention methods, atta

8、chments and supporting garnish moldings (if any) shall be the same as proposed for production. 3.5.2 Short Term Heat, Humidity and Cold Cycle 5 h at -30 +/- 2 C 30 min at 23 +/- 2 C and 50% R.H. 5 h at 90+/- 2 C 30 min at 23 +/- 2 C and 50% R.H. 2 h at 50 +/- 2 C and 95 +/- 5% R.H. 30 min at 23 +/-

Tactually/visually:

10、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: No expansion, shrinking, or warping that will interfer

11、e 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 no evidence of foam crumbling. There shall be no permane

12、nt deformation greater than 2 mm. Results of this test shall be determined by cutting a cross section of the armrest after fatigue flexing.
