Revisions are approved to address the 2009 International Codes, to revise Section 3.3.3.3 to include a provision on the location of the gas burner or wood crib, and to add a new Section 3.4.2.3 to allow testing per NFPA 275 for qualifying nonprescriptive thermal barriers.
3. AC259 — Acceptance Criteria for Power Driven Pins for Attaching Gypsum Board Materials to Cold-formed Steel Wall Framing. Revisions were approved to revise the title of the criteria, to address the 2009 International Codes, to revise the requirements of Section 3.1.3 concerning documenting the properties of the gypsum sheathing used in the testing, to permit small-scale testing and analysis to establish pullout and pull-through strength values, and to revise the ASTM standards referenced in the AC for gypsum board.
4. AC217 — Acceptance Criteria for Concrete with Virgin Cellulose Fibers. Revisions were approved to address the 2009 International Codes and to revise Section A7.0 of Annex A to change the conditions of acceptance for the plastic shrinkage crack testing.
5. AC59 — Acceptance Criteria for Direct-applied Exterior Finish Systems (DEFS). Revisions are approved to allow the use of elastomeric-type direct-applied coating systems on exterior grade plywood substrates.
9. MISC 1 — Policy Concerning the Acceptance of Newer Editions of Design Specifications.

Revisions were approved to allow the sample size to be reduced in cases where a five percent precision of estimate at 95 percent confidence is achieved, to require fastener pull-through capacities be expressed in units of pounds rather than pounds per inch of side member thickness, and to add a requirement that the evaluation report state that the structural members at a connection must also be checked for their load carrying capacity.
17. AC166 — Acceptance Criteria for Metal Roof Coverings. Revisions are approved that set forth requirements for metal roof coverings used as a substitute for roof deck sheathing for the purpose of resisting lateral loads under the International Residential Code. |
