This specification covers cured-in-place thermosetting resin pipe (CIPP) with a certain measurement, equivalent diameter, for use in gravity flow systems in conveying sanitary sewage, storm water, and certain industrial wastes. This specification is suited for the evaluation and testing of materials used in the rehabilitation of existing pipes by the installation and cure of a resin-impregnated fabric liner. CIPP are classified into three types: Type I which is designed to provide chemical resistance and prevent exfiltration; Type II which is installed in a partially deteriorated existing pipe or structure and is designed to provide chemical resistance, prevent exfiltration and infiltration, and support the external hydrostatic loads due to groundwater only (and internal vacuum, where applicable), since the soil and live loads can be supported by the original conduit or structure; and Type III which is Installed in a fully deteriorated existing pipe or structure and designed to provide chemical resistance, prevent exfiltration and infiltration, and support all external hydraulic, soil, and live loads acting on the original conduit or structure. CIPP also are classified into three grades: Grade 1 as thermosetting polyester resin, Grade 2 as thermosetting polyester resin, and Grade 3 as thermosetting epoxy resin. Properties of CIPP materials such as diameter, wall thickness, chemical resistance, flexural strength, and tensile strength shall be determined by subjecting them to different tests.

1.1 This specification covers cured-in-place thermosetting resin pipe (CIPP), 4 through 132-in. (100 through 3353-mm) equivalent diameter, for use in gravity flow systems for conveying sanitary sewage, storm water, and certain industrial wastes. This specification is suited for the evaluation and testing of materials used in the rehabilitation of existing pipes by the installation and cure of a resin-impregnated fabric liner.

1.2 This specification can also be extended to cover manholes, pump stations, wetwells, vaults, storage tanks, and other similar structures where a cured in place liner using thermosetting resin is applicable.

1.3 The values given in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

Note 1—There are no ISO standards covering the primary subject matter of this specification.

1.4 The following safety hazards caveat pertains only to the test methods portion, Section , of this specification: 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.
