2、SIGN 1. SCOPE The material and construction defined by this specification is a low pressure transmission oil cooler hose with low insertion efforts composed of a chlorosulfonated polyethylene (CSM) tube and a chlorosulfonated polyethylene (CSM) or a chlorinated polyethylene (CPE) cover with a single

3、 Aramid fiber braid reinforcement. 2. APPLICATION This specification is released for material used for transmission oil cooler hose assemblies. Hose assemblies shall be suited for 1.7 MPa (250 psi) sustained working pressure. The hose shall be designed to operate through a temperature range of - 40

4、to + 150 C in specified transmission fluid and an ambient air temperature of - 40 to + 125 C with occasional excursions to + 135 C. The hose is for applications with insertion forces requirements of less than 120 N for 5/16“, 3/8“ and 1/ 2” hose inside diameters when pushed onto a standard end form

5、per 3.6.12. 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 HOSE CONSTRUCTION The hose shall consist of a smooth bore chlorosulfonated polyethyle

6、ne (CSM) tube and a chlorosulfonated polyethylene (CSM) or a chlorinated polyethylene (CPE) cover. The reinforcement includes a braided Aramid fabric imbedded in and bonded between tube and cover and free of knots or other defects. The tube and cover are to be heat, oil, ozone, and abrasion resistan

7、t. The cover shall be non-blooming and black in color. The hose is to be suitable for clamped assemblies. 3.3 DIMENSIONS (Inner diameter of hose.) Size A = 5/16” hose Size B = 3/8” hose Size C = 1/2” hose Refer to approved drawing for dimensions. 3.4 MATERIAL TESTING Unless otherwise specified, the

8、following tests shall be performed on specimens cut from the finished hose where required. Test specimens are to be prepared by mechanically separating the hose constituents using a “band-knife splitter“ (preferred) or similar equipment. Alternatively, traditional stripping and buffing techniques ma

9、y also be used. However, different methods of preparation may not yield comparable results. Therefore, whatever method is selected, it should be applied consistently.
