2、g/10 MINUTES 1. SCOPE The material defined by this specification is a molded-in-color thermoplastic acetal copolymer based on trioxane for interior use. 2. APPLICATION This specification was released originally for materials used for decorative and/or functional interior automotive applications such

3、 as loudspeaker grilles, bin latches, and moving parts such as links and sliders. 2.1 LIMITATIONS This material is not intended for painted applications. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Req

4、uirements For Production Materials (WSS-M99P1111-A). Note: 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 minimum, maximum or range was established using 3 si

5、gma data. For 2011 and beyond, refer to Table 1 for number of samples required for each test to establish specification limits. 3.1.1 This specification is based on virgin materials, however materials with recycled content as defined by WRS-M99P42-A1 (post-consumer and/or post industrial recyclates

6、and repolymerised recycled materials) should be used whenever technically feasible and following all materials and PV testing required by Ford Materials Engineering. The use of regrind is permitted, for economic / environmental reasons, with compliance as indicated in WSS-M99P1111-A. 3.1.2 Materials

7、 used in interior applications must meet the requirements outlined in WSS-M99P2222-B1/Latest, Performance, Vehicle Interior Environment Quality Material/Component Requirements. Data must be included in material submission package. 3.1.3 Performance Criteria: Parts using this specification shall meet

8、 the appropriate performance specification, WSS-M15P4-F/Latest for Hard, Interior, Molded-in-Color component performance.

12、 Every 526.4kJ/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 specified

13、 AATCC rating. In addition, there shall be no cracking, crazing or other deterioration. Use regional choice colors for initial approval and report color house used. For color durability submissions, test all program colors. 3.4 MATERIAL PROPERTIES 3.4.1 Melt Flow Rate 7 11 g/10 minutes (ISO 1133, 19
