2、, CONDUCTIVE NOT TO BE USED FOR NEW DESIGN 1. SCOPE This specification defines a reinforced elastomeric hose with a non-barrier layer construction and having a conductive tube that is resistant to diesel fuel. The cover is heat and ozone resistant and manufactured using a “no lead“ cure system. 2. A

3、PPLICATION This specification was released originally for diesel fuel filler hose and vent lines. The maximum working pressure should not exceed 104 kPa. Long term continuous operating temperature should not exceed 100 C and maximum intermittent temperature excursions should not exceed 125 C. This c

4、onstruction is not recommended for bio-diesel applications. 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 TUBE CONSTRUCTION The hose consists o

5、f an inner tube of diesel fuel resistant elastomer such as nitrile rubber (NBR), one ply of braided, knit, or spiral woven fabric, and a cover of heat and ozone resistant elastomer such as chlorinated polyethylene or chlorosulphonated polyethylene (CPE/CSM). Deviations from the above suggested elast
