ASTM C828 – Standard Test Method for Low-Pressure Air Test of Vitrified Clay Pipe Lines
This test method defines procedures for testing vitrified clay pipe lines, using low-pressure air, to demonstrate the integrity of the installed line. Refer to Practice C12.
This test method shall be performed on lines after connection laterals, if any, have been plugged and braced adequately to withstand the test pressure, and after the trenches have been backfilled for a sufficient time to generate a significant portion of the ultimate trench load on the pipe line. The time between completion of the backfill operation and low-pressure air testing shall be determined by the approving authority.
