B. During a pressure test, the safety valve or valves shall be removed or each valve disk shall be held to its seat by means of a testing clamp and not by screwing down the compression screw upon the spring. A plug device designed for this purpose may be used.
C. The temperature of the water used to apply a hydrostatic test shall be no less than ambient temperature, but in no case less than 70° F. The maximum temperature of the water during inspection shall not exceed 120° F.
