Proof pressure test Sample Clauses
A proof pressure test clause requires that equipment or components be subjected to a specified pressure level to verify their structural integrity and leak-tightness before being put into service. In practice, this means that pipes, vessels, or other pressure-containing items must be filled with a test medium—often water or air—and pressurized to a level above their normal operating pressure for a set period, with inspections for leaks or failures. The core function of this clause is to ensure safety and reliability by identifying potential weaknesses or defects before the equipment is used in actual operations.
Proof pressure test. The system is pressurized smoothly and continually with a non-corrosive hydraulic fluid until the target test pressure level is reached and then held for the specified time.
Proof pressure test. The hydrostatic pressure in the cylinder shall be increased gradually and regularly until the test pressure, at least 1.5 times working pressure, is reached. The cylinder test pressure shall be held for a sufficiently long period (at least 30 seconds) to ascertain that there is no tendency for the pressure to decrease and that tightness is guaranteed;
