[Federal Register Volume 75, Number 209 (Friday, October 29, 2010)] [Notices] [Pages 66734-66735] From the Federal Register Online via the Government Publishing Office [www.gpo.gov] [FR Doc No: 2010-27433] ----------------------------------------------------------------------- DEPARTMENT OF COMMERCE National Institute of Standards and Technology [Docket No.: 101006483-0483-02] Proposed Voluntary Product Standard PS 2-10, Structural Plywood AGENCY: National Institute of Standards and Technology, Commerce. [[Page 66735]] ACTION: Notice and request for comments. ----------------------------------------------------------------------- SUMMARY: The National Institute of Standards and Technology (NIST) is soliciting public comment on a proposed revision to Voluntary Product Standard (PS) 2-04, Performance Standard for Wood-Based Structural-Use Panels. This revised standard, PS 2-10, was prepared by the Standing Committee for PS 2 and establishes requirements, for those who choose to adhere to the standard, for the structural criteria to assess the acceptability of wood-based structural-use panels for construction sheathing and single-floor applications. It also provides a basis for common understanding among the producers, distributors, and the users of these products. Interested parties are invited to review the proposed standard and submit comments to NIST. DATES: Written comments regarding the proposed revision, should be submitted to the Standards Services Division, NIST, no later than November 29, 2010. ADDRESSES: An electronic copy (an Adobe Acrobat File) of the proposed standard, PS 2-10, can be obtained at the following Web site: http://gsi.nist.gov/global/index.cfm/L1-5/l2-44/A-355. This site also includes an electronic copy of PS 2-04 (the existing standard) and a summary of significant changes. Written comments on the proposed revision should be submitted to David F. Alderman, Standards Services Division, NIST, 100 Bureau Drive, Stop 2150, Gaithersburg, MD 20899-2150. Electronic comments may be submitted to [email protected]. FOR FURTHER INFORMATION CONTACT: David F. Alderman, Standards Services Division, National Institute of Standards and Technology, telephone (301) 975-4019; fax: (301) 975-4715, e-mail: [email protected]. SUPPLEMENTARY INFORMATION: Proposed Voluntary Product Standard PS 2-10 establishes structural criteria for assessing the acceptability of wood-based structural-use panels for construction sheathing and single- floor application, and provides a basis for common understanding among the producers, distributors, and the users of these products. After conducting a review of the current standard, PS 2-04, the Standing Committee for PS 2 determined that updates were needed to reflect current industry practices, and developed this proposal through meetings to review the standard and propose needed changes. The proposed standard does not address non-structural issues such as resistance to biological agents. Applications for structural plywood other than construction sheathing and single-floor sheathing may require additional engineering considerations that are not covered by this document. The proposed revision of the standard has been developed and is being processed in accordance with Department of Commerce provisions in Title 15 of the U.S. Code of Federal Regulations, part 10, Procedures for the Development of Voluntary Product Standards, as amended (published June 20, 1986). The Standing Committee for PS 2 is responsible for maintaining, revising, and interpreting the standard, and is comprised of producers, distributors, users, and others with an interest in the standard. Committee members voted on the revision, which was approved unanimously. The Committee then submitted a report to NIST along with the voting results and the draft revised standard. NIST has determined that the revised standard should be issued for public comment. The revision includes the following changes:Panel thickness: In order to resolve the inconsistency with NIST standards used by ``weights and measures'' regulators, PS 2 will require labeling with both a ``Performance Category,'' which is a fractional label such as 15/32, and a decimal thickness declaration, such as ``THICKNESS 0.438 IN.'' The Performance Category will maintain consistency with the panel thickness specifications required in the U.S. model codes. The Performance Category panel labeling will permit the abbreviations ``PERF CAT,'' ``CAT'' or ``Category.'' The decimal thickness declaration will help assure that panels are compliant with weights and measures regulations. Two nonmandatory appendices were added to provide guidance on NIST Handbook 130 ``Packaging and Labeling Regulations,'' and to provide suggested thickness labeling. Nonmandatory appendices on attributes related to Green Building and Formaldehyde were added. A nonmandatory appendix on the history of PS 2 was added. The moisture content specifications for the ``dry,'' ``wet/redry'' and ``wet'' test conditions were clarified in various sections of the standard. The tables containing performance requirements were modified to provide clarity and references to the sections of the standard that provide the test methods and pass/fail criteria used during the qualification process. The original fastener holding requirements for sheathing were based on thin plywood panels made with Group 4 species. Those panels are not representative of current sheathing panels. In addition, some U.S. model code requirements for wall sheathing were made more stringent, such that the existing nail holding requirements may not justify certain wind load conditions. Therefore, a test program to characterize the nail holding properties of current production was conducted by two testing agencies. Based on those test results, some requirements for nail holding performance of sheathing were increased. All public comments will be reviewed and considered. The Standing Committee for PS 2 and NIST will revise the standard accordingly. Dated: October 22, 2010. Harry S. Hertz, Director, Baldrige Performance Excellence Program.
