Full Name

ICC-ES AC311 – Acceptance Criteria for Push-fit and Press-connection Fittings for Potable Water Tube and Radiant Heating Systems

Scope

ICC-ES AC311 outlines the acceptance criteria for push-fit and press-connection fittings used for joining copper tubing, CPVC plastic pipe, and PEX piping materials in potable water tube and radiant heating systems. The scope of AC311 includes:

  • Materials: it specifies the requirements for the materials used in the fittings, including copper, CPVC, PEX, and any sealing components, ensuring their compatibility and suitability for the intended applications.
  • Design and construction: it details the design and construction requirements for the fittings, including dimensions, tolerances, and mechanical properties, to ensure their proper functionality and performance.
  • Joint strength and integrity: it outlines the testing methods and acceptance criteria for evaluating the joint strength and integrity of the fittings, ensuring they can withstand the pressures and temperatures encountered in potable water and radiant heating systems.
  • Leakage resistance: it addresses the leakage resistance of the fittings, specifying testing methods and acceptance criteria to ensure they prevent leaks and maintain the integrity of the system.
  • Durability: it assesses the durability of the fittings, including their resistance to corrosion, chemical attack, and other environmental factors, to ensure their long-term performance in various installations.
  • Quality control: it establishes a quality control program to ensure that the fittings consistently meet the requirements of the acceptance criteria, including inspections and testing procedures.

The AC311 acceptance criteria are used by manufacturers to obtain an evaluation report from ICC Evaluation Service (ICC-ES), which demonstrates that their fittings comply with the applicable plumbing codes and standards.
