SCOPE The materials defined by these specifications are finished, full grain, selection “A

4、“, steer hides which have been tanned to retain the natural odor 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 leather. Per

5、forated leather must also meet requirements of para 3.24. 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 specified below. WSB-M1F17-B was released originally f

6、or applications where a lower stiffness interior trim leather is desired. WSS-M1F17-C was released originally for standard wear seat and interior trim applications. WSS-M1F17-D was released originally for molded seat applications formed under heat and pressure. It has improved resistance to blisteri

7、ng when formed with heat, pressure and organic solvents. The use of heat pressure and organic solvents adversely affects the hand and appearance of the leather. For this reason, Materials and Design Engineering must approve processing conditions used for this material prior to its use in a productio

8、n application. WSS-M1F17-E was released originally for high wear seat applications where a high wing sport seat bolsters where improved wear resistance is required. WSS-M1F17-F was released originally for luxury seat applications where a softer hand is desired. 3. REQUIREMENTS 3.0 STANDARD REQUIREME
