2、ATHERING PERFORMANCE, MOLDED-IN-COLOR ESB-M99P22-A2 UNPAINTED RIGID PLASTIC/ELASTOMERIC MATERIALS, INTERIOR TRIM NOT TO BE USED FOR NEW DESIGN 1. SCOPE This specification defines the color stability performance of interior unpainted rigid plastic and/or elastomeric trim materials. 2. APPLICATION Thi
3、s specification was released originally for unpainted molded-in-color or transparent plastic/elastomeric materials that require UV resistance for interior applications. 3.1 STATISTICAL PROCESS Suppliers must conform to the requirements of Ford Quality System Standard Q-101. A mutually acceptable Con
4、trol Plan as described therein is required for material/source approval. Appropriate statistical tools must be used to analyze process/product data so that variation in the final product is continuously reduced. 3.2 WEATHERING RESISTANCE After exposure in accordance with 3.2.1, 3.2.2, and 3.2.3, the
5、 material shall show no color change in excess of specified AATCC rating (AATCC Gray Scale for Evaluating Change in Color, 10 step). In addition, there shall be no cracking, crazing or other deterioration. A slight loss of gloss or chalking will be allowed provided an acceptable appearance can be ac

9、erial upon which approval was originally granted. Prior to making any change in the properties, composition, construction, color, processing or labeling of the material originally approved under this specification, whether or not such changes affect the materials ability to meet the specification re
10、quirements, the Supplier shall notify Purchasing, Toxicology and the affected Materials Engineering activity of the proposed changes and obtain the written approval of the Materials Engineering activity. Test data, test samples and a new code identification are to be submitted with the request. Subs
11、tance restrictions imposed by law, regulations or Ford, apply to the materials addressed by this document. The restrictions are defined in Engineering Material Specification WSS-M99P9999-A1. 4. APPROVAL OF MATERIALS Materials defined by this specification must have prior approval by the responsible
12、Materials Engineering activity. Suppliers desiring approval of their materials shall first obtain an expression of interest from the affected Purchasing, Design and Materials Engineering activity. Upon request, the Supplier shall submit to the affected Materials Engineering activity a completed copy
13、 of their laboratory test reports, signed by a qualified and authorized representative of the test facility, demonstrating full compliance with all the requirements of this specification (test results, not nominal values), the material designation and code number, and test specimens for Ford evaluation. Fords engineering approval of a material will be based on its performance to this specification and on an assessment of suitability for intended processes and/or applications. Upon approval, the material will be added to the Engineering Material Approved Source List.
