ASTM C1618M – Standard Test Method for Concrete Sanitary Sewer Pipe by Negative (Vacuum) Air Pressure (Metric)
This test method covers procedures for testing of precast concrete pipe sections, prior to delivery, where maximum field leakage rates are specified.
Tests described in this standard are intended to be used at the point of manufacture of the concrete pipe and are not intended for testing installed pipe (for field tests see Practices C969 and C1214).
The user of this specification is advised that individual or multiple pipe sections may be tested for the purpose of testing the pipe barrel and additionally the joints in straight alignment when multiple pipe sections are tested.
