Appendix A
Property	Test Information
Short-length elements	The short-length lumber elements are typically 900 mm with an occasional piece of not less than 685 mm. The laminating effect of joining 38 mm × 38 mm short lengths and face-bonding was demonstrated by testing a statistical sample of short-length end-joints, jointed short-length elements, and 38 mm × 140 mm lamina made of short-length elements. In production, the jointed elements are proof-loaded at the full-length.
Tension	Tension testing of 102 samples of various lamina grades was conducted to confirm the design tension values.
Modulus of elasticity	Long span E was confirmed on statistical samples of all grades of lamina.
Moment capacity	The moment capacity predictions were confirmed through testing of sixty (60) beams of 20f and 24f grades at 300-mm and 400-mm depths. Fifteen (15) beams of 600-mm depth were also tested.
Shear capacity	Thirty (30) short beams of 450-mm depth were tested to confirm the characteristic value.
Compression parallel to grain	Thirty (30) short column tests were conducted for 89 mm × 89 mm and 140 mm × 140 mm columns to confirm the characteristic value.
Fasteners	Fastener tests were not conducted to establish an "equivalent" species for fastener design. SPF species are recommended for fastener design as a conservative approach.
Manufacturing quality assurance	The manufacturing quality assurance program follows the principles of CSA O177 and ANSI 190.1, which is verified by APA-EWS as part of the plant qualification.
Adhesives	The face and edge bonding and end joints are bonded with either a phenol-resorcinol adhesive or a polyurethane adhesive. The products are currently qualified with the following adhesives: for end-joints: Ashland UX-100/WD3A22, CCMC 13512-L, and for edge and face laminations: Ashland WD3-A322/CX-47, CCMC 13591-L.
