APPLICATION This specification was released originally for materials used as interior trim coverings for seat, door
3、panels, consoles, IP mid and lower, and armrests. WSS-M8P3-F1 is defined as flexible polymeric film for interior use with standard topcoat that meets haptic and performance specification requirements. WSS-M8P3-F2 is defined as flexible polymeric film for interior use with the additive to meet denim
4、dye barrier requirements while maintaining haptic and performance specification requirements. This suffix level of specification (F1/F2) will go into effect for any new construction and color approvals for MY production 2022. All other model years prior to 2022 were approved under the E suffix and w
5、ill be deemed carry-over for construction and color if there are no changes. New colors for model years prior to MY 2022 on already approved leather/grain combinations but a new color is introduced, this new color must meet the F1/F2 suffix for color properties. 3.
