REQUIREMENTS Material specification requirements are to be used for initial qualification of materials. 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Mat

4、erials (WSS-M99P1111-A). 3.4 CONSTRUCTION The metal or plastic frame is sandwiched with plies of foam. The part is covered with a HF welded PVC sheet. A mirror or a printed label is inserted if specified on engineering drawings. 3.5 COMPRESSION AND RECOVERY After test, the finished part shall not sh

5、ow any visible indentation marks. Test Method: The part shall be indented for one minute with a circular indenter foot of 35.7 mm diameter. Depth of indentation shall be 50% of part thickness. After release, the part shall recover for 2 h prior to examination. ENGINEERING MATERIAL SPECIFICATIONWSK-M

The aged assembly shall not show any change when compared with the original part. Test Method: (FLTM B

10、Q 104-7, Procedure 3.) Mount the finished part according to vehicle installation on a suitable fixture and expose to required cycling condition. After completion of last cycle condition the part for 24 h minimum at standard atmosphere (23/50) prior to examination. 3.8 BOND STRENGTH 3.8.1 Original, m

The maximum breaking strength will be determined using a test speed of 500 mm/min. Note: Bond lines located in the mirror (if applied) area shall not be examined. 3.9 FLAMMABILITY (ISO 3795) Burn Rate, max 100 mm/minute
