Thermoplastics piping systems for underground non-pressure applications. Test method for leaktightness of elastomeric sealing ring type joints Ingestion-build-71203 or replacing the other requirements1 Scope This document specifies a test method for determining the leaktightness of elastomeric sealing ring type joints for buried thermoplastics non pressure piping systems. Unless otherwise specified in the referring standard, the tests are carried out at the following basic test pressures: p1: internal negative air pressure (partial vacuum); p2: a low internal hydrostatic pressure; p3: a higher internal hydrostatic pressure. It also describes the
