2、INTERIOR 1. SCOPE The material defined by this specification is a molded-in-color, talc filled thermoplastic olefin elastomer (TPO) that is UV stabilized for unpainted interior applications with medium impact and stiffness. 2. APPLICATION This specification was released originally for material used

3、for interior trim components such as the 2013 Escape lower IP retainer. 2.1 LIMITATIONS This material is not intended for painted applications. This material should not be used as a hard instrument panel substrate with a seamless passenger airbag. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUC

4、TION 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 the mean and +/- 3 sigma valu

5、es 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 materials. Materials with post-con

6、sumer, post industrial, or repolymerised recycled materials as defined by WRS-M99P42-A1 are preferred and should be used whenever feasible. 3.1.3 The use of regrind is permitted, for economic / environmental reasons, with compliance as indicated in Ford Engineering CAD and Drafting Standard E-4. 3.1

7、.4 Materials used in interior applications must meet the requirements outlined in WSS-M99P2222-D1/Latest, Performance, Vehicle Interior Environment Quality Material/Component Requirements. Data must be included in material submission package. 3.1.5 Performance Criteria: Parts using this specificatio

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

12、ter 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 AATCC rating. In addition, there shall be no cracking,

13、crazing or other deterioration. Use regional choice colors for initial approval and report color house used. For color durability submissions, test all program colors. 3.3.2 Resistance to Scratch and Mar (FLTM BO 162-01, Specimen I) Scratch Rating 2 at 2N, max Whitening/Color Change Rating 1 at 15N,

14、 max Marring Rating 2 at 2N, max These values are derived from colored and grained samples in agreement with Materials Engineering. Details regarding color house, let down ratio, colors, grain, etc can be found in the approval package. 3.4 MATERIAL PROPERTIES 3.4.1 Filler Content 8 - 12 % (ISO 3451-
