The pressure of a hydrostatic leak test performed on a locomotive boiler shall not exceed one and one-fourth (1 1/4) times the MAWP. During the hydrostatic leak test, the safety valve or valves shall be removed, or each valve disk shall be held down by means of a testing clamp and not by applying additional load to the spring with the compression screw. The minimum water temperature used to perform a hydrostatic leak test shall meet the requirements of the applicable construction or repair code; however, the maximum water temperature shall not exceed one hundred twenty (120) degrees Fahrenheit.
