    1、Designation: D7033 07D7033 14Standard Practice forEstablishing Design Capacities for Oriented Strand Board(OSB) Wood-Based Structural-Use Panels1This standard is issued under the fixed designation D7033; the number immediately following the designation indicates the year oforiginal adoption or, in t

    2、he case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONOriented strand board (OSB) wood-based structural-use panels have been used in a vari

    3、ety ofapplications since the 1970s. OSB panels manufactured for use in North America generally complywith U.S. Department of Commerce Standard PS-2. Panels that comply with PS-2 are subjected tovarious kinds of qualification performance testing and ongoing quality assurance testing. While manypanel

    4、applications are specified simply on the basis of meeting a given “span rating” as defined inPS-2, some construction and specialty applications may require a complete set of engineering designvalues. Based on the structural tests required by PS-2 (flexure), along with data for other properties,a set

    5、 of baseline capacities has been available since 1988. As is customary for structural-use panels,design values will be discussed in this practice in terms of design capacities rather than designproperties, where the difference is that a design property is expressed in units of stress (that is,pounds

    6、-per-square inch) and a design capacity is expressed in the engineering units of strength (thatis, inch-pounds of bending strength capacity, pounds of tensile capacity, and so forth). The term“design values” will be used generically and can apply to either properties or capacities.As uses for OSB wo

    7、od-based structural-use panels extend into new applications, it becomesincreasingly important that manufacturers, qualified agencies, and regulatory bodies reference a set ofcommon, consensus-based procedures for establishment of design values. The purpose of this practiceis to provide these common

    8、procedures.1. Scope1.1 This practice covers the basis for code recognition of design capacities for OSB structural-use panels. Procedures areprovided to establish or re-evaluate design capacities for OSB structural-use panels. Procedures for sampling and testing are alsoprovided. Design values state

    9、d as capacity per unit dimension are to be regarded as standard. Design capacities developed inaccordance with this practice are applicable to panels intended for use in dry in-service conditions.NOTE 1This practice is based on ICC-ES Acceptance Criteria AC-182. Relative to the scope of AC-182, this

    10、 practice is limited to OSB panels.NOTE 2While this practice makes reference to PS-2, this practice applies similarly to products certified to other standards such as CAN/CSA O325.NOTE 3OSB produced under PS-2 is rated with the “Exposure 1” bond classification. Exposure 1 panels covered by PS-2 are

    11、intended for dry useapplications where the in-service equilibrium moisture content conditions are expected to be less than 16 %. Exposure 1 panels are intended to resist theeffects of moisture due to construction delays, or other conditions of similar severity. Guidelines on use of OSB are available

    12、 from manufacturers andqualified agencies.NOTE 4PS-2-10 replaced the use of nominal thicknesses with a classification term known as Performance Category, which is defined in PS-2 as “Apanel designation related to the panel thickness range that is linked to the nominal panel thickness designations us

    13、ed in the International Building Code(IBC) and International Residential Code (IRC).” Therefore, the PS-2 Performance Category should be considered equivalent to the term “nominalthickness” used within this standard.2.
