11、fuel tanks AMENDMENT 2 Pages 4(end) and 5: With the purpose of improvement of test sequence/understanding and allowing air to be used for leakage tests, replace Clause 7.2 with: 7.2 Hydraulic pressure test WARNING Do not to exceed the maximum static test pressure. Do not use solutions containing amm
12、onia for testing. 7.2.1 Hydraulic pressure/strength type test A tank representative of the tank series type, with all its accessories, shall be pressure type tested. Prior to the test, non-metal tanks shall be filled with test liquid C in accordance with ISO 1817 or the fuel for which the tank is fa
13、bricated and stored for at least 28 days at an ambient temperature of (21 +2/0)C. The hydraulic pressure test shall be performed immediately after emptying the test liquid out of the tank. The pressure shall be gradually increased to the greater of: 20 kPa; or 1,5 times the highest hydrostatic press
14、ure to which the tank can be subjected in service (maximum fill-up height above tank top). This pressure shall be maintained for: 1 min for metal tanks; 60 min for thermoplastic and fibre reinforced plastic (FRP) tanks with inner coatings having a density 935 kg/m 3 ; and 5 h for thermoplastic and f
15、ibre reinforced plastic (FRP) tanks with inner coatings having a density 935 kg/m 3 . During this time, the tank shell shall not crack or leak; however, it may be permanently deformed. 7.2.2 Leakage test Each fuel tank identical to a type tested tank shall be internally leakage tested with a test pr
16、essure of 20 kPa. Air pressure may be used as an alternative to hydraulic pressure for this test. The test pressure shall be applied for 5 min without pressure drop or rise. After the test, the fuel tank shall not show any leakage when using a leak detection method other than the pressure-drop method. WARNING If air is used for this test care should be taken not to exceed a test pressure of 20 kPa.
