Responses for the February 2013 Evaluation Committee Hearings (received at meeting)

Tuesday, February 12, 2013

  1. AC368 Proposed Revisions to the Acceptance Criteria for Suspended Ceiling Framing Systems. Revisions are proposed to identify and clarify the requirements used in the seismic evaluation of suspended ceiling systems using a comparative testing approach, provide discussion on how the comparative testing approach is currently being used by report holders, and identify the types of recognition that can be permitted using comparative testing.

  1. AC385 Proposed Reinstatement (with revisions) of the Acceptance Criteria for Special-purpose Sprinklers 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. This subject was previously considered by the Evaluation Committee in October 2012 and additional revisions are being proposed to this criteria based on input from the committee and the public at that meeting.

  1. AC434 — Proposed Revisions to the Acceptance Criteria for Masonry and Concrete Strengthening Using Fiber-reinforced Cementitious Matrix (FRCM) Composite Systems. Revisions are proposed based on findings of more recent research and to align the criteria with a guideline that is currently under consideration by ACI Committee 549. Click here.
  1. AC450 Proposed New Acceptance Criteria for Intumescent Fire-resistant Coatings Field-applied to Prefabricated Wood I-joists. A new criteria is proposed to establish performance testing for evaluating intumescent fire-resistant coatings that are field-applied to prefabricated wood I-joists for compliance with Exception 4 to Section R501.3 of the 2012 IRC. Click here.

  2. AC14 — Proposed Revisions to the Acceptance Criteria for Prefabricated Wood I-joists. Revisions are proposed to revise Appendix A to include requirements regarding the evaluation of corrosion effects, durability and mechanical property degradation effects of factory-applied fire protective paints, coatings or treatments where they are used to achieve equivalent fire performance to the materials described in Exception 4 to Section R501.3 of the 2012 IRC.

  1. AC232 — roposed Revisions to the Acceptance Criteria for Anchor Channels in Concrete Elements. Revisions are proposed to the criteria to address the influence of concrete compressive strength on the characteristic shear resistance associated with concrete breakout for anchor channels; revise footnote 5 to Table 4.1 in Annex A; add a new equation 8.13; change in the support spacing in Tests series 10, 11, and 13 of Annex A, Table 4.1; new language regarding the seismic tension and shear tests (Test series 12 and 13 of Annex A, Table 4.1); and a number of other substantive and editorial changes.

  2. AC308 — Proposed Revisions to the Acceptance Criteria for Post-installed Adhesive Anchors in Concrete Elements. Revisions are proposed update the criteria to the 2012 codes and completely revise the criteria to reflect the anchor provisions of ACI 318-11 and the new ACI Standard ACI 355.4. Click here.

  3. AC446 Proposed New Acceptance Criteria for Cast-in Specialty Inserts in Concrete. A new criteria is proposed to establish requirements for the recognition of cast-in specialty inserts in concrete that are subject to tension and shear loads. Click here.
