2、 NOT TO BE USED FOR NEW DESIGN 1. SCOPE: The material defined by this specification is a solvent free, heat curing, polyvinylchloride or other plastics based material with high abrasion and good corrosion resistance. 2. APPLICATION: This material was originally released for non-visible areas of unde
3、rbody and wheel arch. The material is applied to electrocoated surface wet in wet with epoxy spray primer. 3. REQUIREMENTS: Note: Unless otherwise specified use test panels EC-coated according to FLTM BI 120-01, C. The material must be applied on the EC-coated test panel 30 minutes after oven curing
4、. 3.1 STATISTICAL PROCESS Suppliers must conform to the requirements of Ford Quality System Standard Q-101. A mutually acceptable Control Plan as described therein is required for material/source approval. Appropriate statistical tools must be used to analyze process/product data so that variation i
5、n the final product is continuously reduced. 3.2 INFRARED SPECTROPHOTOMETRY AND/OR THERMAL ANALYSIS Ford Motor Company, at its option, may conduct infrared and/or thermal analysis of material/parts supplied to this specification. The IR spectra and thermograms established for initial approval shall
6、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. 3.3 CONDITIONING AND TEST CONDITIONS All test values indicated here
7、in are based on material conditioned in a controlled atmosphere of 23 +/- 2 C and 50 +/- 5 % relative humidity for not less than 24 h prior to testing and tested under the same conditions unless otherwise specified.
