Evaluation of Adhesives for Structural Wood Products (Limited Moisture Exposure)

1.1 This Standard specifies requirements for evaluating adhesives used to bond solid wood materials in structural wood products intended for limited moisture exposure applications. Note: See Annex D for additional information on limited exposure and other moisture exposure categories for structural wood adhesives.

1.2 This Standard specifies requirements for evaluating the resistance of adhesives to (a) shear caused by compression loading, under both dry and re-dry conditions; (b) delamination during accelerated exposure to wetting and drying; and (c) deformation under static shear loading during exposure to heat or high humidity.

1.3 This Standard is not intended for assessment of the effects of chemical treatments of wood on adhesive performance.

1.4 In CSA Standards, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; "may" is used to express an option or that which is permissible within the limits of the standard; and "can" is used to express possibility or capability. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their applicatio
