ICC-ES AC338

Full Name

ICC-ES AC338 – Acceptance Criteria for Rehabilitation of Existing Building Drains and Building Sewers by the Inversion and Curing of Resin-impregnated Tube

Scope

ICC-ES AC338 establishes the acceptance criteria for the rehabilitation of existing building drains and building sewers using the cured-in-place pipe (CIPP) method, specifically through the inversion and curing of a resin-impregnated tube.

The scope of AC338 includes:

  • Materials: it specifies the requirements for the resin-impregnated tube, including its composition, physical properties, and compatibility with existing pipe materials.
  • Installation process: it details the installation process, including pipe preparation, tube insertion, inversion, curing, and post-installation inspection, ensuring a proper and effective rehabilitation.
  • Performance: it outlines the testing methods and acceptance criteria for evaluating the performance of the rehabilitated pipes, including their structural integrity, leak resistance, and flow characteristics.
  • Durability: it addresses the long-term durability of the rehabilitated pipes, ensuring they can withstand the expected service life under various environmental conditions.
  • Quality control: it establishes a quality control program to ensure that the rehabilitation process consistently meets the requirements of the acceptance criteria, including inspections and testing procedures.

The AC338 acceptance criteria are used by manufacturers of CIPP systems to obtain evaluation reports from ICC Evaluation Service (ICC-ES), which demonstrate that their products comply with the applicable plumbing codes and standards.
