For angular travel other than 90°, the endurance shall be agreed between the purchaser and the manufacturer/supplier. c For severe control service duty these values shall be agreed between manufacturer/supplier and purchaser. 4.4 Minimum moving pressure The actuator minimum moving pressure, at ambient temperature, shall be made available, by the manufacturer/supplier upon request. 4.5 Leakage The actuator shall be pressure tested in two stages by applying pressures of 15 to 25 % and a minimum of 143 % of the maximum allowable pressure of the actuator. The actuator shall have no visible external leakage as detailed in Table 8 for the duration of the production test. The test media shall be specified by the manufacturer. The test media always shall be compatible with the operation media of the supplied actuator. The minimum test duration for each test pressure shall be 3 minutes. The test period shall not begin until the test pressure has been reached and has stabilised. The tests gauge pressure reading and time at the beginning and the end of each pressure holding period shall be recorded. 4.6 Moving time The actuator manufacturer/supplier shall state the moving time in both directions, without external load and without valve at working pressure and without any significant external restriction on supply flow, unless otherwise specified.
