2、AIR BAG COVER 1. SCOPE The material defined by this specification is top grain leather made from steer or heifer hides which has been tanned and softened to maximize material haptics. Top coat is a finish that allows for a specialized haptic which is a primary attribute for this leather. 2. APPLICAT

3、ION This specification was released originally as top grain leather for hand wrapped steering wheels, shift knob, shift boot and driver airbag cover applications. 2.1 LIMITATIONS - This leather is not to be used for seating, interior trim, or instrument panel applications - Fully perforated leather

4、is not to be used on steering wheels or shift knobs. - Top coat finish may not meet all Resistance to Colorfastness requirements for Perspiration after Resistance to Interior Weather (section 3.9.6.2 in WSS-M98P12-C2). Testing should be performed per section 3.15 below and submitted as report only i

5、n lieu of 3.9.6.2. 3. REQUIREMENTS For all test methods, no individual measurement shall fall below the minimum values specified herein. In the event of an issue with a test result, testing on the finished part shall prevail. 3.1 APPROVED SOURCES This specification requires the use of approved sourc

6、es. Only the sources identified on the Ford Approved Source List (ASL) can be used when this specification is listed on the drawing, CAD file, or other documents. The list of approved sources is located within Ford at or available externally through a Ford Materials Engineer. 3.2 APPEARANCE The col

7、or, grain, gloss and hand shall match the approved Corporate Design master sample. 3.3 LUXURY LEATHER Leather that is full grained with no alteration to the surface. Minimal top coat is applied to enhance the haptics of the material. 3.4 LEATHER PERFORMANCE Materials manufactured to this specificati

8、on shall also meet the requirements contained in WSS- M98P12-C2/latest. ENGINEERING MATERIAL SPECIFICATION WSS-M1F32-A1 Copyright 2017, Ford Global Technologies, LLC Page 2 of 4 Test plans for both construction and color approvals can be found on Table 1 within WSS- M98P12-C2/latest. 3.5 CONDITIONIN

9、G AND TEST CONDITIONS All test values are based on material conditioned for not less than 24 hrs prior to testing in a controlled environment of 23 +/- 2 C and 50 +/- 5% relative humidity. Testing of the material should occur in the conditioning environment or soon after removal. 3.6 SAMPLE SELECTIO

10、N LOCATIONS The location of the test samples is described in ISO 2418 or ASTM D2813 for physical testing of leather samples. Refer to WSS-M99P12-C2/latest for samples to be taken from the belly and backbone areas as noted in Table 1 of that specification. 3.7 FINISH The leather crust must be similar

11、 in color (minimum 80% color match) to the surface coating. This is to prevent undyed fibers from showing through after sewing. No correcting or repair of any kind shall be allowed including but not limited to buffing, filling, sanding or stuccoing. Buffing is allowed for split leather only. 3.8 THI

GENERAL INFORMATION The information given below is provided for clarification and assistance in meeting the requirements of this specification. Contact for questions co

17、ncerning Engineering Material Specifications. 4.1 TYPICAL STIFFNESS RANGE 65 - 85 mm (FLTM BN 157-02, measurements taken along either side of the backbone.) 4.2 APPROVAL OF MATERIALS Suppliers desiring approval of their materials shall first obtain an expression of interest from Purchasing, Design o

18、r Product Development, and Materials Engineering. The supplier shall submit a completed copy of their laboratory test reports, signed by a qualified and authorized representative of the test facility, demonstrating full compliance with all the requirements of the Material Specification. Tested mater

19、ial samples must be available for review upon request and kept for a minimum of one year. Upon request, the supplier will review the associated quality control documents (Process Failure Mode and Effects Analysis, Control Plans, Certification testing) with Ford. 4.3 SUPPLIERS ONGOING RESPONSIBILITY

20、All materials must be equivalent in all characteristics to the material upon which approval was originally granted. Prior to making any changes to the material originally approved, whether or not such changes affect the materials ability to meet the specification requirements, the supplier shall not

21、ify the affected Supplier Technical Assistance (STA), Purchasing, and Materials Engineering activities of the proposed changes (with reasons) by submission of a completed Suppliers Request for Engineering Approval, SREA. For parts and components using Ford Engineering Material Specifications, all sa

22、mples tested to the specifications for Design Verification (DV), Production Verification (PV) and Production Part Approval Process (PPAP) sign off must be kept until Job 1. 4.4 RESTRICTED SUBSTANCE MANAGEMENT STANDARD Substance restrictions imposed by regulations or Company direction applies to the
