ICC-ES AC04 – Acceptance Criteria for Sandwich Panels


ICC-ES AC04 is a set of acceptance criteria used to evaluate and provide recognition for sandwich panels in ICC-ES evaluation reports, which are issued under various building codes like the International Building Code (IBC), International Residential Code (IRC), and others.

The scope of ICC-ES AC04 encompasses the following:

  • Evaluation procedures: it outlines the procedures and testing requirements for assessing the structural performance, fire resistance, and other relevant properties of sandwich panels.
  • Recognition in evaluation reports: it serves as the basis for determining whether a sandwich panel meets the necessary standards to be recognized in an ICC-ES evaluation report.
  • Application to building codes: the criteria are designed to be applicable to sandwich panels used in construction projects that fall under the jurisdiction of the building codes mentioned earlier.
