4 Test Data: Load Test Load Test Report (for reference only) Machine: Universal or tensile testing machine with a capacity of 5,000 lbs or more. ASTM E74 certified load cell and display to measure load and a dial or electronic indicator accurate to.001 to measure displacement. Specimen: One solar bracket fastened according to the manufactures installation instructions to a 12 x 12 or larger section of the roof substrate. Sealants, flashings and other roofing materials that have no affect on bracket strength may be omitted from the assembly. Apparatus: A welded steel structure reinforced as necessary to prevent buckling, warping or twisting while the specimen is under load. The apparatus is securely fastened to the bed of the testing machine. Setup: Attach the specimen to the apparatus using #14 or #15 self drilling screws in sufficient quantity and spacing so as to prevent failure of the roof substrate prior the failure of the snow guard bracket. Position the apparatus on the test machine bed and connect the load cell to the bracket so that the load is applied as it would be during normal service. Procedure: Photograph the specimen and apparatus prior to testing. Load the bracket slowly with an upward pull until failure. Photograph the specimen after testing. Do a minimum of three tests using a new specimen for each test. If after three tests the results are inconsistent, conduct two additional tests. Failure: Any of the following occurrences shall be considered failure. A. Fastener failure (fracture or withdrawal). b. Structural failure of bracket. Reporting: On the data sheet, record the ultimate load (in pounds) and mode of failure for each test. Calculate and record the mean load for all tests conducted. Note any unusual observations during testing as well as a description of the specific failure observed for each test. Fill out all requested information on the data sheet. Product: EF-SS-44 Test Data Substrate: 1 ½ Spruce Board Failure: Any of the following occurrences shall be considered failure. Test # A. Fastener failure (fracture or withdrawal). B. Structural failure of bracket. Ultimate Load (lbs) Mode of Failure Description A Fasteners withdrew from board A Fasteners withdrew from board A Fasteners withdrew from board Mean Fastener: 2 Olympic XHD 5.4

5 Test Data: Load Test Fastener Pull-Out Comparison To determine the Eco-44 ultimate pull out capacity for your project you will first need to know the single fastener pull out capacity of the fastener you plan to use when fasted in to your roof deck. The best way to determine this is to do an on site pull test. If an on site test is not possible contact the fastener manufacturer and ask for their published pull out data. The estimated Eco-44 ultimate load will be 4 times the single fastener pull out capacity. (Single Screw Pullout Capacity) x 4 = Eco-44 Ultimate Pullout Capacity (No safety factor) For example: Fastener = Triangle #14-13 Concealer Roof Deck = 5/8 CDX Plywood Single Fastener Ultimate Pullout Capacity in 5/8 CDX Plywood = 483 lbs Eco-44 Estimated Ultimate Pullout Capacity = 483 lbs x 4 = 1546 lbs This process determines the expected ultimate load; appropriate safety factor must still be applied. Each plate must be fastened with four fasteners. 5.5

7 Test Data: Leak Test Leak Test Report tested the EcoFasten roof mount system so you can be sure your roof penetrations won t leak, even when under standing water. Our test apparatus encapsulates the entire bracket and seals against the membrane flashing which allows us to flood the bracket and pressurize the system. A paper towel was inserted above and below the base plate in this mock installation to provide a visual indication if any of the green water leaks past the flashing. The membrane is a 45mil reinforced EPDM from Carlisle. 5.7

8 Test Data: Leak Test Leak Test Report The apparatus is pressurized to 30psi and left to stand for over 10 minutes. This is equivalent to nearly 70ft of standing water. The green water leaks past the flashing. The membrane is a 45mil reinforced EPDM from Carlisle. The patented compression fitting between the cone shape of the base plate and the countersink in the bracket makes the EcoFasten system water tight. Water finds its way between the bracket and membrane but stops at the base of the compression fitting and can go no further. Neither of the paper towels shows any indication of leaking. The EcoFasten system is 100% water tight. 5.8
