2、E The material defined by these specifications is an unsupported polymeric film used in soft interior components that require a flexible (soft) cover skin material. This cover material is to be used over a hard substrate with or without foam or spacer fabric. WSS-M2F173-B2 describes material with bi
3、axial orientation characteristics. 2 APPLICATION These specifications were released originally for unsupported polymeric film materials to be used in applications such as in the manufacture of sun visors, door panels, interior tonneau covers, and quarter trim panels. The HF-welding procedure may be
4、 used as specified on Engineering Drawings. 3.

12、 Copyright 2015, Ford Global Technologies, Inc. Page 3 of 3 The material shall not exhibit any change in appearance, such as color tone change, fading in excess of the required AATCC rating. In addition, the material shall not exhibit staining, blistering, or delamination. 3.5 CURL TEST The test spe
13、cimen must not raise itself at any point more than 10 mm when tested as follows: Die cut across the width of the material four test specimens 100 x 100 mm in size with two of these taken at a distance of 25 mm from the selvedges of the roll. Place each specimen immediately on a smooth flat supportin
14、g surface (face side up) and measure the maximum distances between the supporting surfaces and the underside of the specimens. After 15 minutes, repeat the same measurement and report the greatest degree of curl. 3.6 WELDABILITY The material must be capable of being HF-welded under normal production
15、 conditions to the appropriate other materials released for production and/or to itself, without any difficulties, and it must exhibit no faults or defects after HF-welding. 3.6.1 Bonded Seam Strength (FLTM BN 151-01) Original 65 N/50 mm min After Aging 55 N/50 mm min After Humidity Aging 45 N/50 mm min 4.
