Description

ASTM C1244M-93

Historical Standard: Standard Test Method for Concrete Sewer Manholes by the Negative Air Pressure (Vacuum) Test (Metric) (Withdrawn 2003)

ASTM C1244M

Scope

1.1 This test method covers procedures for testing precast concrete manhole sections when using the vacuum test method to demonstrate the integrity of the installed materials and the construction procedures. This test method is used for testing concrete manhole sections utilizing mortar, mastic, or gasketed joints.

1.2 This test method is intended to be used as a preliminary test to enable the installer to demonstrate the condition of the concrete manholes prior to backfill. It may also be used to test manholes after backfilling; however, testing should be correlated with the connector supplier.

1.3 This standard does not purport to address all of the safety problems, 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.

1.4 This test method is the companion to inch-pound Test Method C1244.

Note 1-Vacuum test criteria presented in this test method are similar to those in general use. The test and criteria have been widely and successfully used in testing manholes. Note 2-It should be understood that no correlation has been found between vacuum (air) and hydrostatic tests.
