These durations do not include the time to pressurize the test segments, time for temperature stabilization, or the time for depressurizing the test segments. [...] The test period should begin when the pressure of the test medium stabilizes. [...] See 4(d) and (e) of the guide material under §192.513 for an explanation of the calculations used to prepare this table. [...] (3) Whenever test pressure is 20% SMYS or greater and air, natural gas, or inert gas is the test medium, the line must be checked for leaks either by a leak test at a pressure greater than 100 psig but less than 20% SMYS or by walking the line while the pressure is held at 20% SMYS (§192.507(b)). [...] See 2 of the guide material under §192.509 and 4 of the guide material under §192.513.
