SCOPE The material defined by this specification is needled flat felt, nonwoven unbacked carpet of good quality and uniform composition. 2. APPLICATION This specification was originally rel

3、eased for material used as a covering fabric for package trays only. This material must always be bonded 100 % to a substrate material to lock in the surface fibers and meet all the requirements specified herein. 3. REQUIREMENTS Material specification requirements are to be used for initial qualific

4、ation of materials. In addition to the requirements listed herein, the end-item carpet or trim assembly (molded or otherwise fabricated, shall meet all applicable requirements of WSS-M15P6-D and other requirements specified on the engineering drawing. 3.1 QUALITY SYSTEM REQUIREMENTS Material supplie

5、rs and part producers must conform to the Companys Quality System Requirements. 3.2 INFRARED SPECTROPHOTOMETRY AND/OR THERMAL ANALYSIS IR spectra and thermograms established for initial approval shall constitute the reference standard and shall be kept on file at the designated material laboratory.

6、All samples shall produce IR spectra and thermograms that correspond to the reference standard when tested under the same conditions. 3.3 CONDITIONING AND TEST CONDITIONS All test values indicated herein are based on material conditioned in a controlled atmosphere of 23 +/- 2 C and 50 +/- 5 % relati

7、ve humidity for not less than 24 h prior to testing and tested under the same conditions unless otherwise specified.
