1.0 General Information 1.1 Product Lancaster Series 1.2 Type Aluminum Level Guardrail System 1.3 Project Description TEST REPORT Rendered to: KEYLINK FENCING & RAILING, INC. 150 Orlan Road New Holland, Pennsylvania 17557 Report No.: Test Date: 06/04/13 Report Date: 07/05/13 Architectural Testing was contracted by Keylink Fencing & Railing, Inc. to conduct structural performance tests on the 10 ft wide by 42 in high Lancaster Series aluminum level guardrail system. The system was evaluated for the design load requirements of the following building codes: 2012 International Building Code, International Code Council 2012 International Residential Code, International Code Council Structural tests were performed according to Chapter 17 (Structural Tests and Special Inspections) of IBC 2012. Exception: The test load of two times the design load was not held for 24-hours. The rationale is that guardrail systems are not subject to long term sustained loads such as snow loads and floor live loads. 130 Derry Court York, PA 17406-8405 phone: 717-764-7700 fax: 717-764-4129 www.archtest.com
Page 2 of 7 1.4 Limitations All tests performed were to evaluate structural performance of the guardrail assembly to carry and transfer imposed loads to the supporting structure. The test specimens evaluated included the infill, rails, rail brackets, and support posts. Anchorage of support posts to the supporting structure is not included in the scope of this testing and would need to be evaluated separately. 1.5 Qualifications Architectural Testing in York, Pennsylvania has demonstrated compliance with ANS/ISO/IEC Standard 17025 and is consequently accredited as a Testing Laboratory (TL-144) by International Accreditation Service, Inc. 1.6 Guardrail Assembly Description The Lancaster Series level guardrail system consisted of aluminum top and bottom rails with spaced aluminum balusters between the rail members. The guardrail system had an overall top rail length (inside of post to inside of post) of 120 in with an overall rail height (top of top rail to bottom of bottom rail) of 40 in. Top and bottom rails attached to aluminum support posts via die-cast aluminum socket brackets. See drawings in Appendix A and photographs in Appendix B for additional details. 1.7 Component Description Keylink Fencing & Railing, Inc. provided the test components with the following details: Top Rail: 3-1/4 in high by 2-13/16 in wide (0.09 in wall) contoured 6105-T6 aluminum extrusion Bottom Rail: 3-1/4 in high by 1-1/2 in wide (0.09 in wall) 6105-T6 aluminum extrusion Baluster (In-Fill): 1 in square (0.06 in wall) 6063-T6 aluminum extrusion Rail Brackets: A360.1 cast aluminum socket brackets contoured to shape of rails Fasteners: #12-14 by 1 in (0.160 in minor diameter) square drive, flat-head, self-drilling, sheet metal screws (six in bracket/post) #10-16 by 3/4 in (0.138 in minor diameter) square drive, pan-head, self-drilling, sheet metal screws (two in rail/bracket - opposing each other on opposite sides) Post: 4 in square (0.130 in wall) hollow, recessed 6105-T6 aluminum extrusion attached to a 5-1/2 in square by 1/2 in thick 6105-T6 aluminum base plate with a 1/4 in fillet weld all around. The base plate had four 3/8 in diameter holes located at each corner on 4-7/8 in centers for attachment to substructure. See drawings in Appendix A and photographs in Appendix B for additional details.
Page 3 of 7 2.0 Structural Performance Testing of Assembled Railing Systems 2.1 Test Equipment The guardrail was tested in a self-contained structural frame designed to accommodate anchorage of the guardrail assembly and application of the required test loads. The specimens were loaded using an electric winch mounted to a rigid steel test frame. High strength steel cables, nylon straps, and load distribution beams were used to impose test loads on the specimens. Applied load was measured using an electronic load cell located in-line with the loading system. Electronic linear motion transducers were used to measure deflections. 2.2 Test Setup The guardrail assemblies were installed and tested as a single railing section by directly securing the posts onto steel channels (to simulate attachment into concrete) with four 5/16 in Grade 8 bolts. Transducers mounted to an independent reference frame were located to record movement of reference points on the guardrail system components (ends and mid-point) to determine net component deflections. See photographs in Appendix B for individual test setups. 2.3 Test Procedure Each test specimen was inspected prior to testing to verify size and general condition of the materials, assembly, and installation. No potentially compromising defects were observed prior to testing. An initial load, not exceeding 50% of design load, was applied and transducers were zeroed. Load was then applied at a steady uniform rate until reaching 2.0 times design load in no less than 10 seconds. After reaching 2.0 times design load, the load was released. After allowing a minimum period of one minute for stabilization, load was reapplied to the initial load level used at the start of the loading procedure, and deflections were recorded and used to analyze recovery. Load was then increased at a steady uniform rate until reaching 2.5 times design load or until failure occurred. The testing time was continually recorded from the application of initial test load until the ultimate test load was reached. 2.4 Test Results The following tests were performed on the guardrail assemblies for the design load requirements of the codes referenced. Deflection and permanent set were component deflections relative to their end-points; they were not overall system displacements. All loads and displacement measurements were horizontal, unless noted otherwise. Key to Test Results Tables: Load Level: Target test load Test Load: Actual applied load at the designated load level (target) Elapsed Time (E.T.): The amount of time into the test with zero established at the beginning of the loading procedure.

Architectural Testing 2.5 Page 6 of 7 Summary and Conclusions With the exception of the 71% deflection recovery during the concentrated load on the support post, the Lancaster Series guardrail met the performance criteria of 75% deflection recovery from 2.0 times design load and withstood an ultimate load of 2.5 times design load. The test results substantiate compliance with the design load requirements of the referenced building codes for the 10 ft by 42 in Lancaster Series aluminum level guardrail system reported herein. Anchorage of support posts to the supporting structure is not included in the scope of this testing and would need to be evaluated separately. 3.0 Closing Statement Detailed drawings, data sheets, representative samples of test specimens, a copy of this test report, and all other supporting evidence will be retained by Architectural Testing for a period of four years from the original test date.
