SCOPE
2、 The material defined by this specification is a molded in color, medium heat resistant injection molding compound based on acrylonitrile butadiene styrene (ABS) that has been UV stabilized for interior applications. Medium heat resistant ABS is defined as must having a mean Vicat Softening Temperat
3、ure range from 99 C to 102 C. 2. APPLICATION This specification was released originally for material used for visible interior body parts in medium heat locations such as seat components, floor console or door trim and non-visible applications such as door panels and brackets. 3. REQUIREMENTS 3.1 ST
4、ANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material 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
5、 the mean and +/- 3 sigma values were to be reported. 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 This specification is based on virgin mate
6、rials; however materials with recycled content as defined by WRS-M99P42-A1 (post-consumer and/or post industrial recyclates and repolymerised recycled materials) should be used whenever technically feasible. 3.1.3 The use of regrind is permitted, for economic / environmental reasons, with compliance
7、 as indicated in Ford Engineering CAD and Drafting Standard E-4. 3.1.4 Materials used in interior applications must meet the requirements outlined in WSS-M99P2222-D1/Latest, Performance, Vehicle Interior Environment Quality Component and Allergen Requirements. Data must be included in material submi
8、ssion package. 3.1.5 Performance Criteria: Parts using this specification shall meet the appropriate performance specifications: All mold-in-color components using this material must comply with all the requirements of WSS-M15P4-F/Latest for interior applications.
