ANSI O5.4.2017 provides minimum specifications for the quality and dimensions of wood poles that are to be used
as single-pole utility structures. The poles described herein are considered as simple cantilever members subject
to transverse loads only. Fiber strength values, provided as a basis for determining pole class sizes, apply only to
poles that meet or exceed the minimum quality specifications.
Requirements for the preservative treatment of poles are outside the scope of this standard. However, where
such treatment or conditioning may affect strength, limitations are provided in section 5.1.2. [Also see standards
such as those published by American Wood Protection Association (AWPA) and ASTM International (ASTM)].
