SCOPE The material defined by these specifications is tanned top grain or split leather made from steer hides. The finish coating shall be a series of pigmented or clear resins to ensure compliance to all require

3、ments of these specifications. 2. APPLICATION These specifications were released originally for split or top grain leather for hand wrapped steering wheels, shift knobs, and shift boots. 3. REQUIREMENTS For all test methods, no individual measurement shall fall below the minimum values specified her

4、ein. In the event of an issue with a test result, testing on the finished part shall prevail. 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements for Production Materials (WSS-M99P1111-A). 3.2 SAMPLE SELECTION Sa

5、mples should be prepared for testing according to ASTM D 1610. 3.3 APPEARANCE The color, grain, visual aesthetics, hand and finish shall be approved by Ford Design/Mastering. Hides shall not exhibit defects or surface blemishes affecting the appearance approval of the material. 3.4 FINISHING Dyed le

6、ather with multiple finish coatings applied. The leather must be through dyed to prevent undyed fibers from showing through after sewing and the dye must be similar in color to the surface coating. No correcting or repair of any kind shall be allowed including but not limited to buffing, filling, or

7、 stuccoing.

Condition a 76 x 76 mm sample of material for 10 minutes in 55 C +/- 1 C water. Remove and secure onto a 25.4 mm diameter dowel. The sampl

26、e may be held in place by clamps. The material should be held taught and stationary during the test. 3. Position the cloth so it covers 180 of the sample without touching the seam. Weight the free end of the cloth with a 1.36 +/- 0.05 kg (3 lb) mass and attach the other end to the reciprocating mach

27、ine. 4. Ensure a smooth stroke with a length of 95 +/- 2 mm. One rise and fall of the weight equals one reciprocating stroke. The test shall run at 50 +/- 2 reciprocating strokes per minute. 5. Run the test for 1,500 reciprocating strokes at an ambient air temperature of 21 +/-3 C. 6. Keep the cloth

28、 saturated with room temperature water to prevent the sample from overheating and to maintain a constant coefficient of friction. 7. Record the number of cycles when wear becomes apparent. Suggest checking every 500 cycles. 8. Test a total of 3 samples using a new cloth for each sample. The duck clo
