Subject: Quick Mount PV Load Testing - Tile Replacement Mount

[QMPV# 1-28-2016-Rev C]

Ms. Rodriguez,

In accordance with your authorization, Construction Testing Services (CTS) performed load testing on the Quick

Mount PV 1-1/4” OD by 4-1/2” long post attached to the Tile Replacement Mount. Structural tests included tensile

(uplift), compressive (downwards), lateral (Parallel and perpendicular to rafter), and resultant load applied at a 6:12

roof slope/pitch. The Tile Replacement Mount was fastened to a 2”x4” Douglas Fir Rafter using (2) 5/16” diameter

by 4” long GRK RSS Rugged Structural Screws. Testing was conducted in general accordance with industry

standard testing procedures, including ASTM D1761-12, D2395-14, and ICC AC13.

Test Equipment

Equipment used to perform the various tests include:

 Instron 100HDX Universal Tensile/Compression Machine; Calibrated 10/16/2015

 Delmhorst BD-2100 Moisture Meter; Calibrated daily

 Quincy Lab Inc. 21-250 Oven; Calibrated 04/14/2015

 Digital Caliper AB11881; Calibrated 04/13/2015

 AE Adam PGL 30001 Scale; Calibrated 04/13/2015
