A surface finish may be applied to enhance abrasion resistance and/or surface friction. Color stripping for redyeing

4、of webbing rejected for color is not allowed. The webbing shall be of good quality and uniform construction. 2. APPLICATION This specification was originally released for materials used in the manufacture of seat belts. This webbing acts as a load limiting device (similar to mechanical torsion bar b

5、ased retractor systems). 3. REQUIREMENTS In addition to the requirements listed herein, materials approved to these specifications must also meet all applicable requirements of marketplace National Standards such as C/FMVSS 209, ECE 16, ADR 4, JIS D4604, etc. Material specification requirements are

6、to be used for initial qualification of materials. 3.1 QUALITY SYSTEM REQUIREMENTS Material suppliers 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

7、constitute the reference standard and shall be kept on file at the designated material laboratory. All samples shall produce IR spectra and thermograms that correspond to the reference standard when tested under the same conditions.
