The shear capacity of the specimens was established by combining data in accordance with ASTM D 5055-04. Data from quality control (QC) tests have been used to establish the applicable coefficient of variation, CV_w. The reliability normalization factor from Table 13.2.3.2 of CAN/CSA-O86-01 was used to determine the specified strength.

The moment capacity qualification was carried out using the analytical method based on the characteristics of the flange material, with confirmatory testing in accordance with ASTM D 5055-04. Data from QC tests have been used to establish the applicable coefficient of variation, CV_w. The reliability normalization factor from Table 13.2.3.2 of CAN/CSA-O86-01 was used to determine the specified strength.

An appropriate test program was used to confirm the stiffness capacity. The following formula was used to predict mid-span deflection:

Deflection $\Delta =\frac{5w{L}^4}{384EI\times {10}^3}+\frac{w{L}^2}{Kd}$

where: w = load (kN/m), L = span (mm), EI and K are taken from Table 4.1.1 and d = joist depth (mm)

The flanges for the products do not include any end joints.

Specimens were tested for creep performance in accordance with ASTM D 5055-04. The specimens recovered more than 90% of the basic dead load deflection.

The product reaction properties listed in Table 4.1.2 are specific to bearing lengths shown and are based on a rational bearing analysis methodology applicable to "Red-I™ Series Joists." Data submitted confirm satisfactory performance to the rational methodology. Reaction properties for end or intermediate bearing lengths within ranges shown in Table 4.1.2 may be determined by linear interpolation. Extrapolation of reaction properties in Table 4.1.2 is not allowed.

The adhesive used complies with CSA O112.7-M1977, "Phenol and Phenol-Resorcinol, Resin Adhesives for Wood (Room- and Intermediate-Temperature Curing)." See CCMC 13054-L. The heat durability of the adhesive was confirmed using ASTM D 7247-07a according to ASTM D 5055-07.

The web stock complies with CAN/CSA-O325.0-92 (R2003), "Construction Sheathing."
