2、NTERIOR 1. SCOPE The material defined by this specification is 15% glass fiber reinforced, heat and UV stabilized polyamide 6 molding compound for interior use. 2. APPLICATION This specification was released originally for material used for interior window garnish on the CD34X. 2.1 LIMITATIONS This
3、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 Material suppliers and part
4、 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. The specification
5、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 This specification is based on virgin materials, however materials with recycled content as defined by WRS-M99P42-
6、A1 (post-consumer and/or post industrial recyclates and repolymerised recycled materials) should be used whenever technically feasible and following all materials and PV testing required by Ford Materials Engineering. 3.1.3 The use of regrind is permitted, for economic / environmental reasons, with
7、compliance as indicated in Ford Engineering CAD and Drafting Standard E-4. 3.1.4 Dry as molded All test values indicated herein are based on material and specimens with moisture content not exceeding 0.2% except where noted (Moisture Conditioned) (test according to ISO 15512 Method B/ASTM D6869). Al
8、l test materials have to 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. ENGINEERING MATERIAL SPECI

Individual specimens shall not be removed from closed containers until immediately before testing. 3.1.5 Materials used in interio
10、r applications must meet the requirements outlined in WSS-M99P2222-C1/Latest, Performance, Vehicle Interior Environment Quality Material/Component Requirements. Data must be included in material submission package. 3.1.6 Mold-in-color parts using this material must comply with all the requirements o
11、f WSS-M15P4-F or latest. 3.2 SAMPLE PREPARATION Unless otherwise specified all tests shall be carried out on injection molded, one-end 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 require
12、d. 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 1.0 +/- 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

14、dure 1) Every 526.4J/m2 remove the samples from the weatherometer and allow them to cool for one hour. Conduct a tactile evaluation and report any tackiness. Visually evaluate and report any spewing or other exudation. After exposure the material shall show no fading or color change in excess of the
15、 specified AATCC rating. In addition, there shall be no cracking, crazing or other deterioration. Use black for initial approval and report the color house used.
