Significance and Use
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 performance requirements of PS-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. 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.
