ASTM C – 11() – Standard Test Method for Low-Pressure Air Test of Vitrified Clay Pipe Lines
We have no amendments or corrections for this standard. 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.
For the low pressure used for the test, pressure is inversely related to volume. The test time doubles, also.

Therefore, the average leakage per joint remains unchanged. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
Need more than one copy? 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. Refer to Practice C The time between completion of the backfill operation and low-pressure air testing shall be determined by the approving authority.
