IAPMO IGC 351-2018a Applied in Place Pipe Rehabilitation (AIPPR) Systems

1 Scope
1.1 General
1.1.1 This Standard covers applied in place pipe rehabilitation (AIPPR) systems intended for use in 40 to 200 mm (1.5 to 8 in) gravity and pressure applications such as DWV, sanitary sewer, storm sewer, electrical conduit, ventilation, process piping, and non‐potable supply piping systems and specifies requirements for materials, physical characteristics, performance testing, and markings.
1.1.2 Applied in place pipe rehabilitation systems (AIPPR) covered by this Standard
(a) employ a general purpose two component polyurea derived from the reaction product of an isocyanate component and a synthetic resin blend component through step‐growth
polymerization; and,
(b) are applied to the pipe and fitting system through using spray, brush or troweling to a
finished thickness of not less than SDR100.
