Contact Materials Engineering (FoE) for status) 1. SCOPE The material defin
3、ed by this specification is 30% glass fiber reinforced, heat and UV stabilized polyamide 6 molding compound for interior use. Materials with recycled content should be used whenever feasible. 2. APPLICATION This specification was released originally for material used for interior functional parts. 2
4、1 LIMITATIONS This material absorbs and retains moisture. Part design and tolerances must accommodate changes in part dimensions and physical properties due to moisture absorption or loss in the service/assembly environment. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Materia
5、l suppliers and part producers must conform to the Companys Standard Requirements for Production Materials (WSS-M99P1111-A). 3.1.1 Many 4D resin specifications prior to 2011, identified certain requirements with the symbol (s), which indicated that the mean and +/- 3 sigma values were to be reported
6、 The specification minimum, maximum or range was established using 3 sigma data. For 2011 and beyond, refer to Table 1 for number of samples required for each test to establish specification limits. 3.1.2 WSS-M4D664-B1 is based on virgin materials. 3.1.3 WRS-M4D664-B2 must contain XX% of recycled c
7、ontent as defined by WRS-M99P42-A1. The remaining portion of the material can come from virgin sources. 3.1.4 The use of regrind is permitted for economic and environmental reasons with compliance as indicated in WSS-M99P1111-A.

All test materials have to
9、be sealed in moisture-proof containers and stored at 23 +/- 2 C for at least 24 h immediately after processing. If the moisture content exceeds 0.2%, conditioning the material for a minimum of 16 h at 40 to 50 C at a reduced pressure below 133 kPa. Conduct tests in a controlled atmosphere of 23 +/-
10、2 C and 50 +/- 5% relative humidity. Individual specimens shall not be removed from closed containers until immediately before testing. 3.1.6 Materials used in interior applications must meet the requirements outlined in WSS-M99P2222-C1/Latest, Performance, Vehicle Interior Environment Quality Mater
11、ial/Component Requirements. Data must be included in material submission package. 3.1.7 Mold-in-color parts using this material must comply with all the requirements of WSS-M15P4-F or latest. 3.2 SAMPLE PREPARATION Unless otherwise specified all tests shall be carried out on injection molded, one-en
12、d gated test specimens. The test specimens A and D shall be molded using molding conditions defined in ISO 1874-2. See Tables 1 and 2 for the number of samples required. Specimens shall be as follows: Specimen A 150 minimum x 10 x 4.0 +/- 0.2 mm (ISO 527-2, Specimen Type 1A) Specimen B 355 x 100 x 1
13、0 +/- 0.1 mm (ISO 3795) Specimen C 145 x 60 x 3.2 +/- 0.2 mm Specimen D Center of Specimen A, 80 x 10 x 4.0 +/- 0.2 mm Specimen E 100 mm diameter x 3.2 mm Specimen F 80 mm diameter x 3.2 mm Specimen G 90 mm x 200 mm Specimen H 50 +/- 1 mm diameter x 3.2 +/- 0.2 mm Specimen I 100 mm x 150 mm, min 3.
