SCOPE The material defined by these specifications is finished, full grain, selection “A“, steer hide which has been tanned and softened to provide maximum seating

3、comfort without sacrificing the leathers remaining physical properties. 2. APPLICATION These specifications were released originally for material used as interior trim leather. Perforated leather must also meet requirements of para 3.7, achieved by using a sealer known as flesh coating, to bind any

4、loose fibers and to ensure flesh side fibers will not be visible thru perforation holes on the A surface. Because the hand and appearance characteristics will be adversely affected, the leather shall not be subjected to steam heat or organic solvents during any manufacturing process except as specif

5、ied below. No correcting or repair of any kind shall be allowed including but not limited to buffing, filling or stuccoing. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Mater

6、ials (WSS-M99P1111-A). 3.2 CONTROL ITEMS Control items must be run per the matrix below for the initial approval. Test specimens must be taken equally from the areas described in Figures 1 and 2 for Control Items. The Construction approval package must contain the Initial Approval Control Items and

7、the rest of the specification and be submitted to Materials Engineering and North American Seat Engineering. Once the leather is construction approved then control items must be completed per the matrix below on the same lot of the DV and PV Ingress/Egress covers. These results must also be submitte

8、d to Materials Engineering and North American Seat Engineering before Ingress/Egress testing (ST-0035) is approved. Control items must be tested on every lot (production load) of material; control of these items must be represented in the PFMEA and control plan. These results must be readily availab

9、le and submitted to North American Seat Engineering upon request. After the review and sign-off of the control documents (PFMEA, CP and SPC data) for a significant number of lots, the frequency of the testing can be reduced as agreed upon by the Materials Engineering and North American Seat Engineer

10、ing representatives. Other testing in this specification is for initial approval or on an “as requested“ basis and is not required for annual recertification.
