Specimens were tested in edgewise and flatwise bending for qualification and for establishing volume effects. A non-parametric, 5% tolerance limit with 75% confidence level approach was used to determine the characteristic value. Qualification test data have been used to establish the applicable coefficient of variation, CV_w, and the reliability normalization factor from CSA O86-14 was used to determine the specified strength.

Specimens were tested edgewise and flatwise orientation. A non-parametric, 5% tolerance limit with 75% confidence level approach was used to determine the characteristic value. Qualification test data have been used to establish the applicable coefficient of variation, CV_w, and the reliability normalization factor from CSA O86-14 was used to determine the specified strength.

Specimens were tested edgewise and the average stress at a 1.0-mm deformation was determined. This value was multiplied by 1.09 to establish the specified strength.

Specimens were tested flatwise and the lower of the average stress at 1.0-mm deformation or the average stress at the proportional limit was determined in accordance with ASTM D 5456-14b. This value was multiplied by 1.81 to establish the specified strength in accordance with CSA O86-14 Update No. 1.

Specimens were tested and a non-parametric, 5% tolerance limit with 75% confidence level approach was used to determine the characteristic value. Qualification test data have been used to establish the applicable coefficient of variation, CV_w, and the reliability normalization factor from CSA O86-14 was used to determine the specified strength.

Specimens were tested in tension for qualification and to establish volume effects. A non-parametric, 5% tolerance limit with 75% confidence level approach was used to determine the characteristic value. Qualification test data have been used to establish the applicable coefficient of variation, CV_w, and the reliability normalization factor from CSA O86-14 was used to determine the specified strength.

Nail withdrawal values were established following ASTM D1761-06, "Standard Test Methods for Mechanical Fasteners in Wood," for an 8d common nail having a 31.75-mm penetration. Twenty specimens were tested and the equivalent specific gravity along with the equivalent species combination was determined in accordance with ASTM D 5456-01, A2.

Dowel bearing strength was determined as per ASTM D 5764-95, "Standard Test Method for Evaluating Dowel- Bearing Strength of Wood and Wood-Based Products," with 10d common nails with a nominal diameter of 3.76 mm and a lead hole diameter of 2.77 mm. Forty specimens (10 specimens for four combinations of load direction) of each LVL were tested and the mean bearing capacity was used to establish the equivalent specific gravity and equivalent species combination as per ASTM D 5456-01, A2.

Bolt bearing capacity as per ASTM D 5764-95 with 12.5-mm and 19.0-mm bolts was determined. Twenty specimens (10 specimens for two combinations) of each LVL were tested and the mean bolt bearing capacity was used to establish the equivalent specific gravity and equivalent species combination as per ASTM D 5456-01, A2.

Thirty specimens of "Pacific Woodtech LVL" were tested within a three-month creep and recovery test program, resulting in acceptable performance demonstrating equivalency to duration of load behavior of lumber.

The phenol-formaldehyde adhesive used in the manufacture of this LVL complies with O112.6-M1977, "Phenol and Phenol-Resorcinol Resin Adhesives for Wood (High-Temperature Curing)." See CCMC 13019-L. A phenol resorcinol formaldehyde adhesive (Momentive 4001 / 5830 hardener), used in the secondary face-bonding process when face-bonded at a certified laminating plant, conforms to CSA O112.9-10, "Adhesives for Structural Wood Products (Exterior Exposure)." See CCMC 13522-L. LT75/FM260 phenolic resorcinol formaldehyde adhesive, used in the secondary face-bonding process when face-bonded at another certified laminating plant, conforms to CSA O112.7-1960, "Resorcinol and Phenol-Resorcinol Resin Adhesives for Wood (Room- and Intermediate-Temperature Curing)."

The bond quality was evaluated in accordance with Section 6.7.2 of ASTM D 5456-10a based on longitudinal shear (block shear) tests per Section 14 of ASTM D 143. The test results confirmed the longitudinal (flatwise) shear design value of 2350F_b-1.9E and evaluated the percentage of wood failure. The average percentage of wood failure tested was deemed to be acceptable (no less than 85%).

The product durability was evaluated in accordance with Section 6.8.1 of ASTM D 5456-10a based on the single vacuum-pressure-soak cycle edgewise bending tests. The test results indicated that the 3100F_b-2.0E LVL met the ASTM D 5456 edgewise bending durability requirement which requires the average strength retention to be at least 75%.
