SCOPEThe material described by this specification is a hose of Ethylene/AcrylicRubber, (75 IRHD-A, 65 IRHD-A2) internally reinforced with a single ply ofbraided textile and resistant to e

3、ngine oils.2. APPLICATIONThe ma terial was released originally for use as crankcase drain hoses andturbo c harger air hoses where resistance to long term exposure to engineoils up to 150 EC a nd air temperatures up to 150 EC are required. The hoseis also capable of withstanding short term oil temper

4、atures up to 175 ECand maintaining flexibility down to - 40 EC.3. REQUIREMENTS3.1 QUALITY SYSTEM REQUIREMENTSMaterial suppliers and part producers must conform to Quality SystemRequirements, QS-9000. Material specification r equirements are to beused fo r initial qualification of materials. A Contro

5、l Plan forong oing production verification is required. This plan must bereviewed and approved b y the relevant Ford Materials activity and/orFor d Supplier Technical Assistance (STA) prior to production partssubmission. Appropriate statistical tools must be used to analyzepr ocess/product data and

6、assure consistent processing of thematerials.Part producers using this material in their products, must use Fordapproved materials and must conform to a process control plan whichhas been approved by STA and/or the relevant Materials Activity.3.2 INFRARED SPECTROPHOTOMETRY AND/OR THERMAL ANALYSISFor

7、d Motor Company, at its option, may conduct infrared and/ortherma l analysis of material/parts supplied to this specification.The IR spectra and thermograms established for i nitial approval shallconst itute the reference standard and shall be kept on file at thedesignated material laboratory. All s

8、amples sha ll produce IR spectraand thermograms that correspond to the reference standard when testedunder the same conditions.ENGINEERING MATERIAL SPECIFICATIONWSD-M96D30-A WSS-M96D30-A2WP 3948-b Page 2 of 5 3.3 CONDITIONING AND TEST CONDITIONSAll test values indicated herein are based on ma terial
