ASTM C828
ASTM C828
(OP)
Air testing of a sanitary sewer installation under ASTM C828 calls for pressure to remain above 2.5 psig for a duration that is proportional to the length of line being tested. This seems counter-intuitive to me. If only a few pipe joints are subject to pressure in testing a shorter sewer line, why is an allowable pressure loss per joint reduced when testing a longer sewer line?
