(2) The tested values have been taken from the referenced ATI test report, RADCO has not independently verified any of the actual dimensions, and is not responsible for the accuracy of these dimensions. CONCLUSION: There have either been no changes in the dimensional requirements in the IBC, IRC and the FBC or, as in the case of the Tread Leading Edge Radius, the requirements have been slightly relaxed, when compared to the requirements listed in the referenced"ATI test report number 01- 3701104, dated 11/7/03. The product is therefore in compliance with the dimensional requirements of all editions of the IBC, IRC and the FBC referenced above for the four (4) dimensions shown in the tables. Please call if you have, any questions.
