ASTM C – Standard Test Method for Low-Pressure Air Test of Vitrified Clay Pipe Lines
Therefore, the average leakage per joint remains unchanged. Subscription pricing is determined by: Download Now White Paper: Download Now Defense manufacturing is all about project manufacturing and project accounting. The time between completion of the backfill operation and low-pressure air testing shall be determined by the approving authority.
Both the number of joints and the volume of air in the pipe double. The test is about the volume of air lost, not the pressure. For the low pressure used for the test, pressure is inversely related to volume. Defense manufacturing is all about project manufacturing and project accounting.
Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. The procedures detailed here should be performed on lines after adequately and properly plugging and bracing connection laterals, if any, and after the trenches are backfilled for a sufficient time.

We have no amendments or corrections for this zstm. 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? Historical Version s – view previous versions of standard.
The Eng-Tips staff will check this out and take appropriate action. This test method contains procedures using low-pressure air for testing the integrity of installed vitrified clay pipe lines such as gravity-flow sewer pipes. astj
Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. This test method can also be used as a preliminary test to demonstrate the condition of the line prior to backfill and further construction activities.
