1. Issues

Anecdotal information indicates that corrosion of fasteners has been observed across a range of installations
The problem is more serious in coastal environments due to presence of chloride ions
Increased manufacturing of these products outside the United State may be contributing to the problem
The 2014-2015 corrosion study focused on electrogalvanized roofing fasteners. The results present a baseline for comparison of the performance of fasteners conforming to ASTM A641 or TAS 114 Appendix E standards

3. Statement of Work

Cyclic Corrosion Testing equipment (Q-Lab Corporation) was purchased for the 2014-2015 study
Apply TAS 114 Appendix E testing (Section 2.6.1) to evaluate the degree of corrosion resistance of ASTM A641 Class 1 fasteners and TAS 114 Appendix E certified fasteners
Procurement of test specimens will target both US and non-US manufactured fasteners as permitted by available information. All available descriptive information regarding tested specimens will be included in the reporting
Testing will be conducted on both new and installed/removed fasteners to determine the influence of installation on corrosion resistance
Testing will include multiple samples of each specimen configuration
Fasteners to be tested include:

1 ¼” roofing nails
Roof tile fasteners
Metal roof fasteners

Interpret results, determine if additional Code changes are necessary, and produce a report that explains the results and implications for the Code

4. Deliverables

· An interim report detailing the current status and progress toward completing the scope of work will be submitted by February 15, 2016. The interim report will be presented to the Commission’s Roofing Technical Advisory Committee at a time agreed to by the Contractor and the Department’s Project manager.

· A final report providing technical information on the problem background, results and implications to the Code submitted to the Program Manager by June 1, 2016. The final report will be presented to the Commission’s Roofing Technical Advisory Committee at a time agreed to by the Contractor and the Department’s Project manager.

· A breakdown of the number of hours or partial hours, in increments of fifteen (15) minutes, of work performed and a brief description of the work performed. The Contractor agrees to provide any additional documentation requested by the Department to satisfy audit requirements.
