This Appendix is not a mandatory part of this Standard. There is currently no published standard for fabrication tolerances of tubular pole-type structures.
It has i d r e xsa left to the purchaser to negotiate these requirements with the fabricator. There is a need to provide t n i t s some guidelines for these negotiations. This Appendix sets out some of the critical values that apply to e u a e these structures.
Pole Sections n o i t u b The values for pole sections are i r t s i d a a length: Slip Joints s r u e t The values for slip joints are a s i l i t u ‘ a inside diameter of outside section: Assembled Poles n o e s The values for assembled poles are: Poles with slip fit splices are susceptible to creep or shortening at the joints due to self-weight and load effects.
These formulas are based t.
