4.1?The procedures described in this practice are intended to be used to establish design capacity (both strength and stiffness) values based on testing of OSB that, at a minimum, satisfies the relevant performance requirements of PS 2. 4.2?Review and reassessment of values derived from this practice shall be conducted on a periodic basis. If a change is found to be significant, retesting or reevaluation, or both, in accordance with the procedures of this practice shall be considered. |

|
1.1?This practice covers the basis for code recognition of design capacities for OSB structural-use panels. Procedures are provided to establish or re-evaluate design capacities for OSB structural-use panels in flatwise and axial applications. Design capacities for OSB structural-use panels in edgewise applications, such as rim board, are outside the scope of this standard. Procedures for sampling and testing are also provided. Design values stated as capacity per unit dimension are to be regarded as standard. Design capacities developed in accordance with this practice are applicable to panels intended for use in dry in-service conditions. Note 1:?This practice is based on ICC-ES Acceptance Criteria
AC-182. Relative to the scope of AC-182, this practice is limited
to OSB panels.
Note 2:?While this practice makes reference to PS 2, this
practice applies similarly to products certified to other standards
such as CAN/CSA O325.
Note 3:?OSB produced under PS 2 is rated with the Exposure 1
bond classification. Exposure 1 panels covered by PS 2 are intended
for dry use applications where the in-service equilibrium moisture
content conditions are expected to be less than 16 %. Exposure 1
panels are intended to resist the effects of moisture due to
construction delays, or other conditions of similar severity.
Guidelines on use of OSB are available from manufacturers and
qualified agencies.
Note 4:?PS 2-10 replaced the use of nominal thicknesses with a
classification term known as Performance Category, which is defined
in PS 2 as A panel designation related to the panel thickness range
that is linked to the nominal panel thickness designations used in
the International Building Code (IBC) and International Residential
Code (IRC). Therefore, the PS 2 Performance Category should be
considered equivalent to the term nominal thickness used within
this standard.
1.2?The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.3?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
