SCOPE The material defined by this specification is finished, full grain, steer or heifers hide which has been chrome free tanned to retain the natural odor of the leather. 2. APPLICATION This specification was
3、 released originally for material used as instrument panel leather for the CD345 Mondeo. This material must meet the requirements of WSS-M15P45-B/latest and the appropriate Instrument Panel SDS. If this material will be part of an integrated airbag/instrument panel system then the material must also
4、 meet the requirement of the appropriate airbag SDS. 3. REQUIREMENTS For all test methods, no individual specimen shall fall below the minimum values specified herein. Material specification requirements are to be used for initial qualification of materials. 3.1 STANDARD REQUIREMENTS FOR PRODUCTION
5、MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements for Production Materials (WSS-M99P1111-A). 3.1.1 Vehicle Interior Environment Quality Materials/Component Performance Requirements Materials used in interior applications must meet the requirements out
