SCOPE The material defined by this specification is a heat stabilized glass fiber reinforced polyamide 6 molding compound UV stabi
3、lized for interior use. 2. APPLICATION This specification was released originally for material used for interior functional automotive applications. NOTICE: This material absorbs and retains moisture. Part design and tolerances must accommodate changes in part dimensions and physical properties due
4、to moisture absorption or loss in the service/assembly environment. 3. 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 Standar
5、d Requirements For Production Materials (WSS-M99P1111-A). 3.3 CONDITIONING AND TEST CONDITIONS All test values indicated herein are based on material conditioned in a controlled atmosphere of 23 +/- 2 C and 50 +/- 5% relative humidity for not less than 24 h prior to testing and tested under the same
6、 conditions unless otherwise specified. All test values indicated herein are based on material and specimens with moisture content not exceeding 0.2% (test according to ISO 960, Method B/ASTM D 789). All test materials immediately after processing have to be sealed in containers that are impermeable
7、 to water vapor. If the moisture content exceeds 0.2%, condition the material for a minimum of 16 h at 40 - 50 C at a reduced pressure below 133 Pa.
