SCOPE The performance characteristics defined by this specification may be used to evaluate the environmental resistance of elastomeric parts in the passenger compartment. 2. APPLICATION This specification was released originally

3、to be used in conjunction with industry standards or material specifications to provide a coherent structure for all environmental testing of elastomeric parts. An elastomeric part is defined as a material with a Durometer A hardness of 90 and below (Such as Soft TPEs TPE-V, SEBS, TEEE, TPU, etc) wh

Testing must be conducted on parts when possible. 2.1 LIMITATIONS Not applicable for dynamic sealing (WSS-M9P9-C/latest), weather strips (WSS-M9P10-B/latest), throw in mat assemblies (WSS-M9P11-A/latest), cargo/trunk mats (WSS-M9P11-A2/latest). 3. REQUIREMENTS 3.1 APPROV

5、ED SOURCES This specification is performance based and does not have approved sources. 3.2 CONDITIONING AND TEST CONDITIONS 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

6、the material should occur in the conditioning environment or soon after removal. 3.3 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 for DV/PV testing. 3.4 APPEARANCE Color, gloss, grain, tactile e
