Sec. 406.  Inspection, testing and purging.

 

         Section 406.4 is hereby amended as follows:

 

         406.4.  Test pressure measurement.  Test pressure shall be measured with a manometer or with a pressure-measuring device designed and calibrated to read, record, or indicate a pressure loss caused by leakage during the pressure test period. The source of pressure shall be isolated before the pressure tests are made.

 

         Section 406.4.1 is hereby amended as follows:

 

         406.4.1.  Test pressure.  The test pressure to be used shall be no less than ten (10) pounds per square inch (69 kPa) gauge pressure, or where approved by the building official, the piping and valves may be tested at a pressure of at least six (6) inches (152.4 mm) of mercury, measured with a manometer or slope gauge.  For welded piping, and for piping carrying gas at pressures in excess of fourteen (14) inches (0.4 m) water column pressure, the test pressure shall be no less than sixty (60) pounds per square inch (413 kPa).  Where the test pressure exceeds one hundred twenty-five (125) psig (862 kPa gauge), the test pressure shall not exceed a value that produces a hoop stress in the piping greater than fifty percent (50%) of the specified minimum yield strength of the pipe.

 

         Section 406.4.2 is hereby amended as follows:

 

         406.4.2.  Test duration.  Test duration shall be not less than fifteen (15) minutes or for welded pipe and piping carrying gas at pressures in excess of fourteen (14) inches (0.4 m) water column pressure, the test duration shall be not less than thirty (30) minutes.  The duration of the test shall not be required to exceed twenty-four (24) hours.

 

         Section 406.4.3 is hereby added as follows:

 

         406.4.3.  Test Gauges.  Tests required by this code which are performed utilizing dial gauges shall be limited to gauges having the following pressure increments or graduations:

 

         406.4.3.1.  Required pressure tests of ten (10) pounds (69 kPa) or less shall be performed with gauges having increments of one-tenth (1/10) pound (0.69 kPa) or less.

 

         406.4.3.2.  Required pressure tests exceeding ten (10) pounds (69 kPa) but less than one hundred (100) pounds (690 kPa) shall be performed with gauges having increments of one pound (7 kPa) or less.

 

         406.4.3.3.  Required pressure tests exceeding one hundred (100) pounds (690 kPa) shall be performed with gauges having increments two (2) psi (14 kPa) or less.

 

         406.4.3.4.  Pressure tests required by this code, which are performed utilizing dial gauges, shall be limited to a gauge having a maximum gauge rating not exceeding twice the applied test pressure.
