Subject: Quick Mount PV Load Testing
ICC-ES AC13 & ASTM D 1761
Dear Mr. Wentworth:
As requested, Applied Materials & Engineering, Inc. (AME) has completed load-testing Quick Mount
PV system anchors for shear and tensile strength. The purpose of our testing was to evaluate the tensile
and shear load capacity of the Quick Mount PV system in a high density (Douglas Fir) and a low density
wood (Cedar).
SAMPLE DESCRIPTION
Twelve (12) 12"x12" samples were delivered to our laboratory on 10-16-08; six each for Douglas Fir
and Cedar. A copy of the installation instructions is provided in Appendix A. Typical sample photo is
provided in Appendix B.
PROCEDURES & RESULTS
Since an acceptance criterion (AC) has not been developed for this product, the samples were tested
under the direction of Mr. Yamil Moya, P.E. with ICC-ES, and in general accordance with applicable
procedures outlined in ASTM D 1761 and AC13.
a. Tensile Strength
Three samples each of the two types of wood were tested for tensile strength on October 24 & 27, 2008
using a United Universal testing machine. Samples were rigidly attached to the testing machine and a
tensile load was applied to the 5/16"x6" hanger bolt at a displacement rate 0.1 inches per minute without
shock until failure. Detailed results are provided in Table I. Based on these results, the average tensile
strength of the hanger bolt in Douglas Fir and Cedar wood species were determined to be 3934 lbs and
2214 lbs, respectively.

b. Shear Strength
Three samples each of the two types of wood were tested for shear strength on Octobet 24 &27,2008
using a United Universal testing machine. Samples were rigidly attached to the testing machine and a
shear load was applied to the 2-114"x1-1/4"x1-114" aluminum mount at a displacement rate 0.1 inches
per minute without shock until failure. Detailed results are provided in Table II. Based on these results,
the average shear strength ofthe hanger bolt in Douglas Fir and Cedar wood species were determined to
be 4365 lbs and 3313 lbs, respectively.
Photographs illustrating typical setup and typical failure modes are shown in Figure I and II.
If you have any questions regarding the above, please do not hesitate to call the undersigned.
