2、NS 1. SCOPE The material defined by this specification is a U.V. stabilized thermoplastic polyolefin EPDM rubber modified (TEO). The material can be processed by conventional thermoplastic molding techniques such as injection and/or extrusion molding. 2. APPLICATION The specification was released or
3、iginally for material used for roof profile skin. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.2 DYNAMIC MECHANICAL ANALYSIS (ASTM D 4065) Ford
4、Motor Company, at its option, may establish shear modulus/damping vs. temperature curves plotted for - 50 to + 170 C temperature range for material/parts supplied to this specification. The shear modulus and damping curves established for initial approval shall constitute the reference standard and
5、shall be kept on file at the designated material laboratory. All samples shall produce shear modulus and damping curves that correspond to the reference standard when tested under the same conditions. 3.3 MATERIAL TESTING 3.3.1 Preparation of Test Specimens Whenever possible, all test specimens shal
6、l be die-cut from the finished parts. When not feasible, molded specimens are manufactured from the same material and with equivalent cure to the molded parts are recommended. The molded specimens respect the dimensions required by the specific test. 3.4 ORIGINAL PROPERTIES 3.4.1 Density, +/- 0.05 g

Page 3 of 3 3.7 WEATHERING RESISTANCE After exposure in accordance with 3.7.1, 3.7.2 and 3.7.3 the material shall show no color change in excess of specified Gray Scale rating (AATCC Evaluation Procedure 1/ ISO 105-A02). In addition, there shall be no cracking,
12、crazing or other deterioration. A slight loss of gloss or chalking will be allowed provided an acceptable appearance can be achieved by washing and/or polishing with Ford car polish (auto wax) after the outdoor exposure, by permission of the affected Product Development Materials Activity.
