2.0 PROCEDURE

Testing was conducted in accordance with ICC-ES AC378, section 4.1, referencing ASTM E72, Section 12 – Transverse Loading – Specimen Vertical.

Test Method Test Description

ICC ES AC 378 Section 4.1, Referencing ASTM E72, Section 12 Transverse Loading

Transverse Loading – ICC-ES AC378, section 4.1, ref erencing ASTM E72, Section 12

Six (6) wall assemblies was constructed for three (3) positive and three (3) negative loadings in accordance with ICC-ES AC378, Section 4, Referencing ASTM E72 to a specified deflection limit of L/360 (6.77 mm / 0.266 inches of net deflection). Prior to testing, the wall assembly was instrumented with three (3) deflection gauges to quantify the assembly movement in relation to induced pressure. The locations of the various deflection gauges used are shown below in Figure 2:

Upon completion of imposing design load to L/360 deflection, the specimens were loaded to failure and the allowable loading shall be based on a safety factor of 3, based on the average L/360 test load.
