2、FORMANCE, MOLDED-IN-COLOR ESB-M99P22-A1 UNPAINTED PLASTIC/ELASTOMERIC MATERIALS, EXTERIOR NOT TO BE USED FOR NEW DESIGN 1. SCOPE This specification defines the color stability performance of exterior unpainted plastic and/or elastomeric materials. 2. APPLICATION This specification was released origi

3、nally for all unpainted molded-in- color plastic/elastomeric materials that are exposed to direct sunlight. 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/sourc

4、e 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, 3.2.3, and 3.2.4, the material shall show no color change in excess of spec

5、ified 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 achieved by washing with mild detergents and water (rati

6、o 5:95 by volume) after Florida exposure only. All initial approvals will be based on the preliminary Weatherometer Exposure, pending Florida Exposure results for final approval. AATCC Rating 3.2.1 Xenon Arc Weatherometer 4 (SAE J1960, 1250 kJ/m2 exposure except Rating 4-5 minimum, specimen size 150

7、 x 100 mm for polyolefins minimum, 3.2 +/- 0.2 mm thick, unless otherwise specified) ENGINEERING MATERIAL SPECIFICATION ESB-M99P22-A1 WP 3948-b Page 2 of 2 AATCC Rating 3.2.2 Florida and Arizona Exposure, 12 months 4 (SAE J1976, Procedure A, 5 deg south, weathering inland, specimen size: 150 x 100 m

8、m, minimum, 3.2 +/- 0.2 mm thick, unless otherwise specified) 3.2.3 Florida and Arizona Exposure, 24 months 3-4 (SAE J1976, Procedure A, 5 deg south, direct weathering inland, specimen size: 150 x 100 mm, minimum, 3.2 +/- 0.2 mm thick, unless otherwise specified) 3.2.4 Townsville Exposure, 18 months

9、 3-4 (20 deg north, open rack) FOA applications only. 3.3 SUPPLIERS RESPONSIBILITY All materials supplied to this specification must be equivalent in all characteristics to the material upon which approval was originally granted. Prior to making any change in the properties, composition, constructio

10、n, 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 requirements, the Supplier shall notify Purchasing, Toxicology and the affected Materials Engineering activity of the prop

11、osed 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. Substance restrictions imposed by law, regulations or Ford, apply to the materials addressed by this document. The restricti

12、ons 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 Materials Engineering activity. Suppliers desiring approval of their materials shall first obtain an expression of inter

13、est from the affected Purchasing, Design and Materials Engineering activity. Upon request, the Supplier shall submit to the affected Materials Engineering activity a completed copy of their laboratory test reports, signed by a qualified and authorized representative of the test facility, demonstrati

14、ng 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.
