2、gies, LLC Page 1 of 5 RUBBER PARTS, INTERIOR AND EXTERIOR WSD-M9P8-A PERFORMANCE NOT TO BE USED FOR NEW DESIGN 1. SCOPE The performance characteristics defined by this specification may be used to evaluate the environmental resistance of visible rubber parts used either externally or in the passenge

3、r compartment. These may include weatherstrips, gaiters, boots and seals etc. The parts may be flock or anti-friction coated on areas specified on the Engineering Drawing. 2. APPLICATION This specification was released originally to be used in conjunction with basic material specifications to provid

4、e a coherent structure for all environmental testing of visible rubber parts. 3. REQUIREMENTS 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.4 CONSTRUCTION As spe

The surface shall be free of blisters, voids and any bloom unless otherwise specified on the engineering drawing. 3.6 FINISH As specified on engineering drawing 3.7 RESISTANCE PRO

6、PERTIES The following requirements shall be assessed on whole parts or sections of weatherstrip assemblies and must include all materials and constructions found within the parts, e.g., molded corners, bright inserts, bonded glass, flock coating, etc. Parts shall be tested to the interior or exterio

7、r requirements as shown on the engineering drawing. Parts such as some window seals may be both interior and exterior and shall be tested accordingly. Separate specimens are required for each test.
