Original Version
Rule 48.6

48.6 Tower or Pole Foundations and Footings
In calculating the resistance of foundations or footings of towers, poles and pole line structures to uplifts, the weight of concrete shall be taken as not more than 145 pounds per cubic foot and the weight of earth (calculated 30 degrees from the vertical) shall be taken as not more than 90 pounds per cubic foot. The resistance of soil to the depression of foundations or footing shall be calculated from the best available data on the soil in question. In lieu of calculation, the strength of foundations or footings against uplift or depression may be determined by tests under the soil conditions prevailing.

48.5 Conductors, Span Wires, Guys and Messengers
Values used for ultimate strengths of wires and cable shall not exceed those given in Appendix B. The ultimate strengths given in Tables 17 , 18 , 19 , 20 , 21 , 23 , 24 of Appendix B , except for medium–hard drawn copper, are based on the minimum ultimate strengths given in the standard specifications of the American Society for Testing Material. The ultimate strengths given in Appendix B for medium–hard drawn copper are based on the standard specifications of the ASTM and provide an allowance above the minimum values of one–quarter of the range between minimum and maximum values. For use of types of wires and cables of other material not included in Appendix B , values for ultimate strengths similarly derived from specifications of the ASTM shall be used except that, if such specifications are nonexistent, maker’s specifications may be used provided that tests have been made which shall justify the maker’s rating for ultimate strength.
