1、 ENGINEERING MATERIAL SPECIFICATION TRIM ASSEMBLY, ENCLOSED LUGGAGE WSS-M15P32-D COMPARTMENT COVERING 1. SCOPE The material defined by this specification is the minimum durability and performance requirements of all enclosed carpeted luggage or load compartment trim components where various material
2、s are combined to provide a trim assembly having decorative and/or functional features. This includes: rear seat back trim in enclosed luggage compartment applications, deck lid trim and spare tire covers (not for exposed load compartment applications). 2. APPLICATION This specification was released
3、 originally for material used as enclosed luggage compartment trim parts. 3.

4、ronment Quality Materials/Component Performance Requirements Materials used in interior applications must meet the requirements outlined in WSS-M99P2222-D1/latest. Data for the component shall be performed at the appropriate program milestone. 3.1.2 In addition to the requirements listed herein, the
5、 individual carpet assembly components shall meet all the requirements of the applicable material specifications for the carpet, padding, adhesive, barrier, or trim application as well as any functional/SDS requirements as outlined by Engineering. 3.2 SAMPLE SELECTION See Table 1 and 2 for sample si
6、ze and testing requirements. When production test specimens are taken from an area in the carpet with padding, the padding should be stripped away as much as possible before evaluation, unless otherwise specified. 3.3 APPEARANCE (FLTM BI 109-01) The color, pattern, and finish shall match the approve
7、d Design Center master sample, or shall be as specified on the Engineering Drawing. 3.4 PHYSICAL PROPERTIES 3.4.1 Shrinkage, Water 2.0% max (FLTM BN 105-01) WMD and AMD Date Action Revisions Rev. 1 2014 07 24 Revised See Summary of Revisions L.
