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 w

3、as released originally 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, S

4、EBS, TEEE, TPU, etc) which fall in the 2D category. Testing must be conducted on parts when possible. See Table 1 for sample size and testing requirements. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard R

5、equirements For Production Materials (WSS-M99P1111-A). 3.1.1 Materials used in interior applications must meet the requirements outlined in WSS-M99P2222-D1/Latest, Performance, Vehicle Interior Environment Quality Material/Component Requirements. Data must be included in material submission package.

6、 3.2 CONSTRUCTION As specified on engineering drawing. 3.3 COLOR AND SURFACE The part shall be as specified on the engineering drawing.

8、representative production support foundations. This includes 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, attachments, and supporting garnish moldings (if

9、any), shall be the same as proposed for production. Test Procedure Visually evaluate the part before, during, and after the test. Measure the part and record data at all specified locations at room temperature before and after cycling on the production support foundation or test fixture. Also, durin
