2、 WSD-M96D14-A3 REINFORCED, ENGINE COOLANT RESISTANT LOW COMPRESSION SET 1. SCOPE This specification defines an internally rayon or polyester fabric reinforced, engine coolant hose. 2. APPLICATION This specification was released originally for a hose connection between the radiator and engine block w

3、here good resistance to compressive creep under securing clamps is required. The hose will withstand coolant and ambient air temperatures up to 120 C but has limited resistance to excessive oil contamination and poor resistance to fuel contamination. If resistance to ambient air or coolant temperatu

4、res above 120 C is required, then the hoses described in WSE-M96D14-A1/A2 or WSD-M96D23-A1 should be considered. Consider using WSE-M96D34-A1, A2 or A3 where resistance to electrochemical degradation is required. (Contact Materials Engineering for selection advice). 3. REQUIREMENTS 3.0 STANDARD REQU

5、IREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production 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

6、 curves plotted for -50 to +150 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 shall be kept on file at the designated material laboratory. All samples shall prod

7、uce shear modulus and damping curves that correspond to the reference standard when tested under the same conditions. 3.5 HOSE CONSTRUCTION The hose shall consist of an inner tube and outer cover of ethylene/propylene rubber (EPDM) with an internal reinforcing layer of a suitable knitted or braided

8、high tenacity rayon or polyester fabric. 3.6 MATERIAL TESTING 3.6.1 Preparation of Test Specimens Whenever possible, all test specimens shall be die-cut from the finished parts. When not feasible, specimens cut from molded test sheets manufactured from the same material and with equivalent cure to m

9、olded parts are recommended.
