Additional Product Test Information^{Footnote (1)}
Property	Test Information
Shear capacity	The shear capacity of the product was established by computing the shear capacity for each depth separately as per ASTM D 5055-04. Qualification tests were used to establish the applicable coefficient of variation, CV_w, and the reliability normalization factor from CSA O86-09 was used to determine the specified strength.
Moment capacity	The moment capacity qualification was carried out using the analytical method in accordance with ASTM D 5055-04. At least 10 specimens of each joist depth were tested to verify the actual capacity versus the design capacity. Qualification tests were used to establish the applicable coefficient of variation, CV_w, and the reliability normalization factor from CSA O86-09 was used to determine the specified strength.
Stiffness	A bending test program of varying depths was used to confirm the stiffness capacity. The following formula was used to predict mid-span deflection: $deflection = \frac{5 w L^{4}}{384 E I \times 10^{3}} + \frac{w L^{2}}{K}$ where EI = shear-free EI from Table 4.1.1, w = uniform load (kN/m), L = span (mm), K = shear deflection factor from Table 4.1.1.
End joints	End joints were qualified as part of the flange tension qualification. The flanges are finger-jointed in plant, and regular tension testing is conducted.
Creep	Product specimens were tested for creep performance as per ASTM D 5055-04, whereby two specimens from each I-joist series group are loaded to 1.5 times the design resistive moment capacity where the average deflection recovery must exceed 90%.
Bearing length	The design values on end bearing and intermediate reaction were analyzed using the procedure in ASTM D 5055-08 whereby linear interpolation was used to establish reaction capacities within the tested bounds of depth and bearing length. A minimum of 10 specimens were tested for four bearing lengths at I-joist extreme depths. Qualification tests were used to establish the applicable coefficient of variation, CV_w, and the reliability normalization factor from CSA O86 was used to determine the specified strength.
Adhesive qualification	The flange-to-flange finger joint is adhered with a polyurethane adhesive (see CCMC 13512-L); web-to-web and web-to-flange joints are bonded with a phenol-resorcinol formaldehyde adhesive complying with CSA O112.7-M1977, "Resorcinol and Phenol-Resorcinol Resin Adhesives for Wood (Room- and Intermediate-Temperature Curing)" (see CCMC 13054-L).
