Composition Flashing Kit and Steel Base Report No. TT 516012A Page 3 of 17 Terrapin Testing Orig. Issue Date: 2016-10-26 Revision Date: 2016-10-26 Revision #: 0.0 Approval: RWC 1.0 INTRODUCTION Solarhooks.com (SHD) contracted with Terrapin Testing (LAB) to perform tests, on its Composition Flashing Kit and Steel Base. The LAB performed tensile and compression tests at its facility in Rancho Cordova, California. Section 3.0 below describes the product configuration. 2.0 REPORT IDENTIFICATION This report titled "Composition Flashing Kit and Steel Base Testing," was prepared by the testing lab, Terrapin Testing, TL-159. The LAB is located at 3206 Luyung Drive, Rancho Cordova, California, 95742-6830. The LAB's unique job number, TT 516012A identifies this report. This report was prepared at the request of SHD. The proponent’s corporate offices and facility are located at 2795 E Bidwell Street, Suite 100, Folsom, California 95630. This report is issued as of the date on the report cover. The tests covered by this report were performed during the months of September and October 2016. Rick Cavanagh, LAB Manager, prepared this report and supervised the tests. His signature is on the report cover. 3.0 SAMPLE DESCRIPTION Flashing Kit: The Composition Flashing Kit consists of an aluminum L-foot, aluminum flashing shingle, EPDM washer and a 3/8-inch, #14 zinc plated lag screw with one EPDM backed stainless steel compression washer. Steel Base: The Steel Base consists of a 304 stainless steel base and two 3/8-inch, #14 zinc plated lag screws with EPDM backed stainless steel compression wash- ers. For the testing, the Steel Base had holes drilled on the entire length of the base. The production model will not include the last three rows of holes. Testing was performed using the fourth row of holes from the end, which simulates the last row of holes in the production Steel Base. The drawing within Appendix A shows what the production Steel Base will be. See product specifications within Appendix A. The LAB did not perform in- dependent verification of any mechanical properties. Composition Flashing Kit and Steel Base Report No. TT 516012A Page 4 of 17 Terrapin Testing Orig. Issue Date: 2016-10-26 Revision Date: 2016-10-26 Revision #: 0.0 Approval: RWC All of the tested components subjected to testing were selected by SHD and delivered to the LAB. The specimens were received in good condition, on September 2 and 28, 2016. 4.0 RESULTS Flashing Kit: The Composition Flashing Kit specimens were installed into a simulated 12”x12” roof deck and subjected to tensile (upward) loading and compres- sion (downward) loading. A 3/16” diameter lead hole was bored into the wood framing membrane prior to inserting each specimen. The simulated roof deck was fabricated by the LAB using Douglas Fir (DF) dimensional 2x4 lumber and 7/16” OSB (APA rated to PS-2 04). The typical flashing was placed on the deck with the hole placed over the predrilled hole in the OSB. The L-Foot was then placed over the hole and securely fastened to the flash- ing/roof by tightening the lag screw. Steel Base: The Steel Base configuration was adhered in a similar manner using two predrilled holes and two lag screws, attached directly to the OSB. The Steel Base configuration was subjected to tensile (upward) loading and compres- sion (downward) loading. The simulated roof deck used was approximately 36” with one section simulating studs 24” on center. The bracket was situ- ated for each test such that the testing was performed to impact the deck in the 24” on center section. In addition, two pieces of OSB were butted to- gether at the stud where the lag screws were attached in an attempt to sim- ulate the worst case situation. This setup is visible in the photos enclosed. During the tensile testing of the Steel Base, load was applied in 50 lb incre- ments, returning to zero after each, up to 400 lbs in order to measure per- manent deflection. After reaching 400 lbs, load was continuously applied until failure. Load application rates for all testing is indicated on Tables 1-4. A total of three (3) specimens were tested for each configuration and direc- tion of load. Figures 1 through 4 document the testing configuration. Ta- bles 1 through 4 report the results of all testing. 1621 W Avalon Ave08/07/23
