SCOPE These specifications define long life, high

3、pressure EPDM rubber coolant hoses internally reinforced with para-aramid fibers (WSE-M96D14-A1) or meta-aramid (WSE-M96D14-A2) fibers. 2. APPLICATION WSE-M96D14-A1 hose specification was released originally for high strength, high temperature applications where resistance to hot coolant and steam i

4、s paramount, such as in by-pass, heater and radiator hoses. The hose will continuously withstand 125 C coolant and 140 C ambient air temperatures. Hose should be used with a good interference fit to compensate for the poor compression set. WSE-M96D14-A2 hose specification was released originally for

5、 the same applications as WSE-M96D14-A1, however it should be specified only where excessive impulse and/or flex resistance are required. 3. REQUIREMENTS 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Pr

6、oduction Materials (WSS-M99P1111-A). 3.3 DYNAMIC MECHANICAL ANALYSIS (ASTM D 4065) Ford Motor Company, at its option, may establish a shear modulus/damping vs. temperature curves plotted for -50 to +150 C temperature range for material/parts supplied to this specification. The shear modulus and damp

7、ing curves established for initial approval shall constitute the reference standard and 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. 3.5 HOSE CO

8、NSTRUCTION The hose shall consist of an EPDM rubber tube and cover internally reinforced with para-aramid fibers (WSE-M96D14-A1) or meta-aramid fibers (WSE-M96D14-A2). The following tests where possible, shall be performed on finished hoses and/or test specimens cut from them in accordance with ASTM

9、 D 3183 (cutting knife procedure preferred). Greater variation in test values can be anticipated when evaluating materials that are thinner than recommended by an applicable Industry Standard/Test Method.
