Memos for the October 2012 Evaluation Committee Meeting

Tuesday October 2, 2012

  1. AC166 — Proposed Revisions to the Acceptance Criteria for Metal Roof Coverings. Revisions are proposed to update the criteria to the 2012 codes, add the 2006 codes, discontinue recognition under the 2003 codes and the UBC, update the wind resistance requirements, update the fire classification requirements to address the 2012 and 2009 codes and apply those requirements to evaluations done to the 2006 codes. Editorial revisions, as needed, are also proposed. Click here.

  2. AC377 — Public Notification of Alternative Methods for Qualifying Spray-applied Foam Plastic Insulation Used in Attics without a Prescriptive Ignition Barrier. ICC-ES staff is notifying industry and seeking input on how we intend to evaluate spray-applied foam plastic insulations used in unvented residential attics using Section 3.12 of the criteria.

  3. AC385 — Proposed Reinstatement (with revisions) of the Acceptance Criteria for Special-purpose Sprinkler Heads Used with Fixed Glazed Assemblies to Provide a Fire-resistance-rated Wall Assembly. It is proposed that the criteria be reinstated and revised to include recognition under the 2012 and 2009 codes. At its June 2011 meeting, the Evaluation Committee declined to approve revisions that were proposed to the criteria at that time and voted to withdraw the criteria that was in effect at that time.

  1. AC368 — Public Notification Regarding Alternate Seismic Qualification of Suspended Ceiling Systems in Accordance with the Acceptance Criteria for Suspended Ceiling Framing Systems. ICC-ES staff is notifying industry and seeking input on the steps necessary to evaluate the use of intermediate duty runners in Seismic Design Categories D, E, and F. Click here.

Wednesday October 3, 2012

  1. AC308 — Proposed Revisions to the Acceptance Criteria for Post-Installed Adhesive Anchors in Concrete Elements. Revisions are proposed to the slice tests in Section 9.8.3 of Annex A; the simulated seismic tension test in Section 9.12.2 of Annex A; and to Sections 3.0, 9.9 and 11.8, as well as Tables 4.1 and 4.2, regarding the corner test.

  2. AC440 — Proposed Acceptance Criteria for Using an Equivalency Approach to Verify Seismic Design Parameters for Lateral-Force-Resisting Vertical Wood Truss Wall Assemblies. A new criteria is proposed to provide requirements confirming the use of metal-plated wooden trusses, referred to as wood truss wall assemblies (WRWA), as substitutes for in-plane shear-resisting vertical components (shear walls) of an otherwise code-complying lateral force-resisting system. This subject was previously considered by the Evaluation Committee in June 2012. Click here.

  3. AC259 — Proposed Revisions to the Acceptance Criteria for Power-Driven Pins for Attaching Gypsum Board Materials to Cold-formed Steel Wall Framing. Revisions are proposed to base allowable pullout values on the more conservative result from wall assembly testing with the thickest CFS wall framing and the wall assembly testing with the thinnest CFS wall framing, delete provisions pertaining to legacy codes, expand the scope of the criteria to address the use of power-driven fasteners for attaching gypsum board materials to CFS of interior walls, clarify that the criteria is limited to the evaluation of negative transverse load capacity, delete all mention of strength design, remove definitions of commonly understood terms, and expand quality control requirements in response to Evaluation Committee action on MISC1-0811-R1 and clarify documentation requirements for fasteners.

  4. AC70 — Proposed Revisions to the Acceptance Criteria for Fasteners Power-driven into Concrete, Steel and Masonry Elements. Revisions are proposed to include the 2009 and 2006 codes so that a single criteria addresses evaluation to the 2012, 2009, and 2006 codes, to apply the more permissive statements allowed by ASCE/SEI 7-10 regarding the use of the fasteners to resist seismic codes to the 2009 and 2006 codes, revise the scope of the criteria so that it is applicable to lower steel thickness, remove conditional statements corresponding to distributed systems where fasteners are placed in steel materials, allow for the use of the fasteners with base materials other than steel, and revise requirements for quality control to indicate the level of technical information to be included in the quality documentation.

  1. AC269.1 — Proposed Acceptance Criteria for Proprietary Sheathing Attached to Wood Light-framed Wall Construction Used as Braced Wall Panels under the IRC. A new criteria is proposed which will update the wall bracing provisions for wood frame construction of AC269 to the 2009 IRC. A prior edition of this criteria was posted on the ICC-ES website for public comment using the June 2011 alternative criteria process and this subject was previously considered by the Evaluation Committee in October 2011.

  2. AC447 — Proposed Acceptance Criteria for Fiber Reinforced Plastic (FRP) Modular Wall Systems. A new criteria is proposed to establish requirements for Fiber Reinforced Modular (FRP) wall systems. Click here.
