SCOPE The material described by these specifications is a hose of Ethylene/Acr
3、ylic Rubber, (75 IRHD-A, 65 IRHD-A2) internally reinforced with a single ply of braided textile and resistant to engine oils. 2. APPLICATION The material was released originally for use as crankcase drain hoses and turbo charger air hoses where resistance to long term exposure to engine oils up to 1
4、50 C and air temperatures up to 150 C are required. The hose is also capable of withstanding short term oil temperatures up to 175 C and maintaining flexibility down to -40 C. 3. REQUIREMENTS 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the
5、 Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.4 HOSE CONSTRUCTION The hose shall consist of an Ethylene/Acrylic rubber inner tube and outer cover with a single layer of suitable braided reinforcing textile. The hose will usually be shaped. 3.5 MATERIAL TESTING Whenever
6、 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 molded parts are recommended. The test sheets shall have the following dimensions: 150 x 150 mm, min x 2.0
