Bending |
Specimens were tested in edgewise and flatwise bending to establish the characteristic value. Data from quality control (QC) tests were used to establish the applicable coefficient of variation, CVw. The reliability normalization factor from CSA O86-09 was used to determine the specified strength. |
MOE |
The 2.0E specimens were tested in edgewise bending to establish the mean MOE. The established mean MOE was 2.2 × 106 psi, and is maintained as indicated in the quality control manual (QCM), and is confirmed by the third-party certification agency to form the qualification for the 2.2E product grade. |
Shear |
Specimens were tested in edgewise and flatwise shear to establish the characteristic value. Data from QC tests were used to establish the applicable coefficient of variation, CVw. The reliability normalization factor from CSA O86-09 was used to determine the specified strength. |
Compression parallel to grain |
Specimens were tested in compression parallel to grain to establish the characteristic value. Data from QC tests were used to establish the applicable coefficient of variation, CVw. The reliability normalization factor from CSA O86-09 was used to determine the specified strength. |
Compression perpendicular to grain |
Specimens were tested in compression perpendicular to grain to establish the characteristic value following ASTM D 5456-14b. The characteristic value was multiplied by 1.81 to establish the specified strength in accordance with CSA O86-14. The original value determined in accordance with CSA O86-09 was maintained since it is more conservative compared to the specified strength when calculated in accordance with CSA O86-14 Update No.1. |
Tension parallel to grain |
Specimens were tested in tension to establish the characteristic value. Data from QC tests were used to establish the applicable coefficient of variation, CVw. The reliability normalization factor from CSA O86-09 was used to determine the specified strength. |
Nail withdrawal |
Nail withdrawal values were established following ASTM D 1761, "Standard Test Methods for Mechanical Fasteners in Wood," for an 8d common nail having a 31.75-mm penetration. Specimens were tested and equivalent species capacity was determined in accordance with ASTM D 5456-07, A2.4. |
Nail bearing |
Dowel bearing strength was determined as per ASTM D 5764-97a(2007), "Standard Test Method for Evaluating Dowel-Bearing Strength of Wood and Wood-Based Products," using 10d common nails with a nominal diameter of 3.76 mm and a lead hole diameter of 2.77 mm. Specimens were tested, and the mean bearing capacity was used to establish the equivalent species capacity as per ASTM D 5456-07, A2.5. |
Bolt bearing |
Bolt bearing capacity was determined as per ASTM D 5764-97a(2007) using 12.5-mm- and 19-mm-diameter bolts. |
Creep and recovery |
Creep testing was conducted in accordance with the creep and recovery test described in ASTM D 5456-07. The specimens met the acceptance criteria of ASTM D 6815, "Standard Specification for Evaluation of Duration of Load and Creep Effects of Wood and Wood-Based Products." |
Adhesive |
The adhesive complies with CSA O112.6-M1977. The adhesive used is from the Hexion Inc., family of Cascophen 84204 (CCMC 13019-L). |
