The applicable edition of Practice E shall be specified in the contractual agreement. General Procedures 6. It is not sensitive enough for leak testing when toxic or explosive gas is expected to be retained under pressure. Interferences 7. New systems should be tested prior to painting, where practical. The liquid test media may clog small leaks causing later tests to be inaccurate. The minimum temperature of the liquid should be 16C 61F. If water is used as a test fluid it should be deionized.
The metal should be a minimum of 16C 61F prior to the application of pressure. Apparatus 8. Pressure gauges should be calibrated before each test. The gauge must read at least 1. See Terminology E for a description of terms. If more than one gauge is used, one may be a recording gauge.
At least one gauge which is used for acceptance of the test shall be calibrated within 30 days prior to use. One indicating gauge must be easily visible to the operator controlling the pressure throughout the pressurizing and testing cycle. Thereafter slowly increase the pressure to the final test pressure. Examination for leakage shall be made of all accessible joints and connections, attachment welds where practical, and weep holes for paddings and attachments.
Also inspect the area around inaccessible leakage sites. The magnitude of leak shall be described in terms of: damp or moist area, drops per minute or steady stream. The air vents need to be opened during draining to admit air and prevent collapsing of the test system.
