This is the third edition of CSA O15, Wood utility poles and reinforcing stubs. It supersedes the previous editions published in 1990 and 1983.

1 Scope

1.1 This Standard covers material, manufacturing, and class dimensional requirements for seasoned wood poles and reinforcing stubs that are primarily intended for the support of electrical power or communication lines.

1.2 This Standard does not cover requirements for wood poles intended for use in structures such as bridges and buildings.

1.3 This Standard does not cover requirements for the preservative treatment of poles or the conditioning of poles prior to treatment. Such requirements are detailed in the CSA O80 Series of Standards unless otherwise specified.

1.4 In CSA Standards, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; "may" is used to express an option or that which is permissible within the limits of the standard; and "can" is used to express possibility or capability.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
