ASTM C969-02
(Practice)Standard Practice for Infiltration and Exfiltration Acceptance Testing of Installed Precast Concrete Pipe Sewer Lines
Standard Practice for Infiltration and Exfiltration Acceptance Testing of Installed Precast Concrete Pipe Sewer Lines
SIGNIFICANCE AND USE
This is not a routine test. The values recorded are applicable only to the sewer being tested and at the time of testing.
SCOPE
1.1 This practice covers procedures for testing installed precast concrete pipe sewer lines using either water infiltration or exfiltration acceptance limits to demonstrate the integrity of the installed materials and construction procedure.
1.2 A complete metric companion to this practice has been developed-C 969M; therefore, no metric equivalents are presented in this practice.
Note 1—The owner shall specify the following: who will conduct, observe, and furnish labor, furnish material and measuring devices, and pay for the tests; who is responsible for determining local groundwater conditions; and which test is to be conducted, that is, an infiltration test or an exfiltration test.
Note 2—The user of this practice is advised that test criteria presented in this practice are similar to those in general use. Pipe, 24-in. diameter or larger, may be accepted by visual inspection when testing for infiltration.
1.3 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.
