Innovative Aluminum Systems Inc. August 21,2008 Report No.3099244C0Q-005A Page 4 of 6 4 Testing and Evaluation Methods The test specimens were loaded at a rate to achieve the specified loads between 10 seconds and 5 minutes. The specified test loads were held for one minute before the load was released. As per ICC-ES AC 273 with reference to the 2006 International Building Code, Section 1607.7.1, Handrails and Guards, the following tests were conducted: 4.1. GENERAL (Clause 4.2.1) One complete railing system, consisting of two posts, was tested at maximum spacing and in the worst-case scenario. 4.2. IN-FILL LOAD TEST(Clause 4.2.2) A load consisting of 125 Ibf was applied over 1 sq. ft. (0.0929 m2) normal to the in-fill in a worst- case scenario. 4.3. UNIFORM LOAD TEST (Clause 4.2.3) The top rail of the system was subjected to a single test where a maximum uniform load of 175 lbf/ft was applied vertically and in an outward direction at an angle 45° from horizontal. The 175 Ibf/ft uniform load met and exceeded the 125 lbf/ft requirement from the 2006 International Building Code and the ICC-ES AC273, Approved 2008. 4.4. CONCENTRATED LOAD TEST(Clause 4.2.4) The top rail of the guardrail system was subjected to two separate tests where a concentrated load of 500 lbf was applied at the following locations: • Horizontally at the centre of the guardrail. • Horizontally at the top rail adjacent to the rail post connection to verify the connection capacity. Deflection measurements at the center of the rail were relative to the posts. Deflection readings were recorded at 200 lbf.
