Hydrostatic Burst Test
1.Fill the test specimens with water or hydraulic fluid which meets the requirements before installation onto the appropriate testing apparatus.
2.Place the test specimens into a burst chamber and secure them into place in accordance with the manufacturer's recommended procedures. One end must be free to move.
3.Equip the chamber with calibrated pressure gages to permit visual readings of actual pressure being applied.
4.Perform the hydrostatic burst test at ambient temperature.
5.Subject the test specimens to a gradual increase of pressure at an average rate not to exceed 127 MPa/min (25 000 psig/min) to four times the rated pressure of the specimen assembly and hold for a minimum of 1 min. If leakage or burst occurs below four times the rated pressure of the specimen assembly, discontinue the test. The affected test specimens have failed the test. Fill out the test report noting the reason for discontinuing the test.
6.The test specimens have passed the hydrostatic burst test when four times the rated pressure of the specimen assembly has been attained.
