This Standard pertains to wood-based panel products, designed and manufactured for protected construction uses as roof sheathing, wall sheathing, and floor sheathing in light frame construction applications. Construction Sheathing panels primarily comprise three types: all wood veneer; part veneer and par t wood furnish; and all wood furnish.
This Standard requires that the binders used to manufacture panels be waterproof and boil-proof. However, conformance to this Standard does not qualify panels as Exterior Type suitable for prolonged or permanent exterior exposure to the elements.
Note: Criteria for panels of Exterior bond quality may be found in CSA Standards O121, O151, O153, CAN3-O188.3, and CAN3-O437.0.
This Standard establishes five groups of Construction Sheathing products relating to end use, each specified by means of prescribed test requirements. Within each group, the Standard establishes levels based on physical, bond durability, and structural performance criteria appropriate for the intended application. It specifies Product Qualification tests and criteria based on the assumption that panels will be installed in accordance with good practice. Other tests and criteria may be required to characterize panels for special construction uses or other applications.
This Standard prescribes certain Control Values (which conform to industry norms) and test methods for establishing other Control Values (which are unique to individual Products). Taken together, these Control Values set limits against which an ongoing quality assurance test program may be established.
This Standard requires that all panels represented as conforming to it be covered by a Mill Specification.
This Standard specifies panel marks that indicate recommended end uses for conforming panels.
This Standard does not cover surface finish of panels such as surface solidity or smoothness.
This Standard provides an alternative, not a replacement to other Standards for wood-based panels. The use of the term Construction Sheathing in this Standard is not intended to imply that panels conforming to other CSA Standards (such as O121, O151, O153, CAN3-O188.3, and CAN3-O437.0) are not construction sheathing panels.
