ASTM C828-06

Standard Test Method for Low-Pressure Air Test of Vitrified Clay Pipe Lines

ABSTRACT
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. 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. 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.
SCOPE
1.1 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 C 12.
1.2 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.
1.3 This test method may also be used as a preliminary test, which enables the installer to demonstrate the condition of the line prior to backfill and further construction activities.
1.4 This test method is suitable for testing gravity-flow sewer pipe constructed of vitrified clay or combinations of clay and other pipe materials.
1.5 Terminology C 896 is to be used for clarification of terminology in this test method.
1.6 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
