SCOPE This specification is commonised for use by Ford Motor Company, Jaguar and Land Rover. The materials defined by this specification are finished, full grain or corrected grain,

3、 selection A steer hides which have been tanned to retain the natural odour of the leather and softened to provide maximum seating comfort without sacrificing the leathers remaining physical properties. 2. APPLICATION These specifications were released originally for material used as interior trim l

4、eather, excluding instrument panel covers, steering wheels. Because the hand and appearance characteristics will be adversely affected, the leather shall not be subjected to steam or radiant heat or organic solvents during any manufacturing process except as specified below. Corrected grain leather

5、shall be snuffed using one pass of 320 grit paper. The method of correction will be agreed with Purchasing and Materials and Body Engineering. 3. REQUIREMENTS For all test methods, no individual specimen shall fall below the minimum values specified herein. 3.1 STANDARD REQUIREMENTS FOR PRODUCTION M

6、ATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production materials (WSS-M99P1111-A). 3.2 SAMPLE SELECTION Samples for testing shall be selected no closer than 80 mm from edge of the hide. 3.3 APPEARANCE (FLTM BI 109-01) The color, grain, visual

7、 aesthetics, hand and finish shall match the approved Design Center master sample, or shall be as specified on the engineering drawing. 3.4 GRADE The leather must be through dyed to prevent undyed fibers from showing through after sewing or perforation. Also, the colour of the dye must be compatible

8、 in appearance with the surface coating. No stuccoing. 3.5 FINISH All hides shall show no paint defects or surface blemishes affecting the appearance of the material, such as brush marks or stops and bad flows.
