AS/NZS 1328.1:1998
Glued laminated structural timber - Performance requirements and minimum production requirements
Specifies product requirements for the timber used, the type of adhesive and the strength of the load in both end and lamination joints. It also gives methods for establishing properties of completed structural pieces so that product may be assigned to a stress grade. Methods of test are given to measure the strength of a glued joint.
