ICC-ES Evaluation Committee Highlights

The ICC-ES Evaluation Committee met February 2-4 in Los Angeles to consider new proposed acceptance criteria for alternate products and for products where additional clarification is needed in the code; and for existing criteria that need to be revised to reflect current code, updated standards or changes to products. Twenty-two separate items were considered, with 18 being approved and eight held for further study.

AC365 — Acceptance Criteria for Building-integrated Photovoltaic (BIPV) Roof Modules and Panels. Revisions were approved to include requirements for BIPV roof modules that self-adhere to the top layer of single-ply membranes or to built-up roofs or to metal roof panels.

AC66 — Acceptance Criteria for Fire-retardant-treated Wood. Revisions were approved to address the 2009 International Codes, to add definitions for fire-retardant-treated wood (pressure process and other means during manufacture) and to reference AC257 for the evaluation of proprietary corrosion-resistant fasteners.

AC203 — Acceptance Criteria for Zinc Borate (ZB) Preservative Treatment of Structural Composite Wood Products by Non-Pressure Processes. Revisions were approved to address the 2009 International Codes and to expand the scope of the criteria to include any structural composite wood product, not just lumber.

AC39 — Acceptance Criteria for Walking Decks. Revisions were approved to address the 2009 International Codes, to provide requirements for walking decks that are not used as roof coverings and to provide requirements for walking decks used with nonclassified roof coverings.

AC417 — Acceptance Criteria for 1/2-inch Sag-resistant Gypsum Ceiling Board Installed with Two-part Polyurethane Adhesive. This is a new criteria that was approved to evaluate ½-inch-thick sag-resistant gypsum ceiling board that is factory installed with its long dimension parallel to framing spaced at 24 inches on center using a polyurethane foam adhesive.

AC391 — Acceptance Criteria for Continuous Rod Tie-Down Assemblies. Revisions were approved to limit the use of continuous rod tie-down assemblies to applications in which they resist wind uplift forces only (eliminating their use in resisting wind and seismic shear wall overturning forces), to require that evaluation reports contain statements that clarify that the scope of such reports are limited to the continuous rod tie-down assemblies themselves (that is, does not include an evaluation of wall framing and other elements within the load path of the continuous rod tie-down assemblies) and to require report holders to submit examples of full system calculations for publication with their evaluation reports.

AC193 — Acceptance Criteria for Mechanical Anchors in Concrete Elements. Revisions were approved to update Table 7.1 of the criteria to bring it into agreement with Table 11.6 of AC308, to revise durability requirements in Section 3.1, and to revise Annex 1 Sections 8.5, 8.7, 9.1, 9.2.2, 9.6, 9.8, 9.9, 10.3, 10.5 and 10.6 and Tables 11.1 and 11.2.

AC70 — Acceptance Criteria for Fasteners Power-driven into Concrete, Steel and Masonry Elements. Revisions were approved to address the 2009 International Codes, to remove legacy codes from the criteria, to identify the types of end uses addressed by the criteria, to require testing laboratories to identify the grade and density of concrete brick and block used in testing, to delete certain provisions related to prescriptive provisions of the codes, to add requirements to address components intended for use as ceiling wire hangers and to revise certain provisions related to edge distance of concrete use in test specimens.

AC46 — Acceptance Criteria for Cold-formed Steel Framing Members. Revisions were approved to address the 2009 International Codes, to remove the Uniform Building Code (UBC) from the criteria, to remove provisions involving field manufacturing and to clarify the requirements for engineering calculations.

AC425 — Acceptance Criteria for Cold-Formed Steel Structural Beams Acting Compositely with Cast-In-Place Concrete Slabs. This is a new criteria that was approved to evaluate cold-formed steel structural beams that act compositely with cast-in-place concrete slabs.

AC86 —Acceptance Criteria for Cold-formed Steel Framing Members — Interior Nonload-bearing Wall Assemblies. Revisions were approved to address the 2009 International Codes, to remove legacy codes from the criteria, to incorporate editorial changes needed to clarify the criteria, to revise provisions relating to the format of limiting height tables and to allow for the use of the updated target reliability index contained in Supplement No. 1 (dated August 2009) to the North American Specification for the Design of Cold-Formed Steel Structural Members, 2007 Edition.

AC347 — Acceptance Criteria for Headed Ends of Concrete Reinforcement. Revisions were approved to address the 2009 International Codes and to align the requirements of the criteria to provisions of ACI 318-08.

AC15 — Acceptance Criteria for Concrete Floor, Roof, and Wall Systems and Concrete Masonry Wall Systems. Revisions were approved to address the 2009 International Codes, to add a section that references AC353 in order to provide further guidance as to data needed to qualify ICFs (insulated concrete forms) and provide provisions for evaluating concrete walls for use in Seismic Design Categories C, D, E and F of the IBC and Seismic Zones 3 and 4 of the UBC.

AC125 — Revisions to the Acceptance Criteria for Concrete and Reinforced and Unreinforced Masonry Strengthening Using Externally Bonded Fiber-Reinforced Polymer (FRP) Composite Systems. Revisions were approved to address the 2009 International Codes and the ACI 440.2R document.
