2、MIDE 12 (PA12) COVER, TIE LAYER, WSS-M98D33-A1 ETFE TUBE, LOW PRESSURE, FUEL/ALCOHOL RESISTANT, NON-CONDUCTIVE, LOW PERMEATING 1. SCOPE This specification defines a Multilayered Tubing with a non-conductive inner layer. The construction has low permeation rates and good resistance to fuel/alcohol bl

3、ends. 2. APPLICATION This specification was released originally for flexible fuel vapor lines requiring low permeation. The maximum working pressure should not exceed 104 kPa. Long term continuous operating temperature should not exceed 90 C and maximum intermittent temperature should not exceed 115

4、 C. These lines will meet the requirements of the US market for both reformulated and flexible fuels. 3. REQUIREMENTS 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A)

5、3.4 PERFORMANCE REQUIREMENTS In addition to those requirements listed below in sections 3.5.1, 3.5.2 and 3.5.6, the tube must meet the requirements for fuel vapor tubing listed in section 7 of SAE J2260.
