前言:这是CSA O15第四版，木质电线杆和加固短柱。它取代了2005年、1990年和1983年出版的之前版本。本版本的主要变化包括杆内扫描的测量方法和对ANSI摄影手册的参考。简介:本标准涵盖加拿大使用的所有商用电杆物种。由于加拿大、欧洲和美国之间存在极点交换，本标准还包括苏格兰松和南黄松的进口物种，并将一些物理属性与其他国家的标准相协调。 在本标准2015年版的制定过程中，小组委员会同意，将对本标准表A.1中未包含的已发布杆试验数据集进行分析，如果认为合适，将在下一版本中相应更新表3中物种的纤维应力和刚度。范围:1.1本标准涵盖主要用于支撑电力或通信线路的干燥木杆和加强短柱的材料、制造和等级尺寸要求。 1.2本标准不包括桥梁和建筑物等结构中使用的木杆的要求。1.3本标准不包括电杆防腐处理或处理前电杆调节的要求。除非另有规定，这些要求在CAN/CSA-O80系列标准中有详细说明。1.4国际单位制给出的数值为本标准中的记录单位。括号中给出的值仅供参考和比较。表1至表23以码/磅为单位，附录E中提供了等效的SI（公制）版本。 1.5在本标准中，“应”用于表示要求，即用户为遵守本标准而有义务满足的规定；“应该”用于表示建议或建议但不需要的建议；“可”用于表示一个选项或在标准范围内允许的选项。注释随附条款不包括要求或替代要求；随附条款的注释的目的是将解释性或信息性材料与文本分开。 表和图的注释被视为表或图的一部分，可以作为要求编写。附件被指定为规范性（强制性）或信息性（非强制性）以定义其应用。

Preface:This is the fourth edition of CSA O15,Wood utility poles and reinforcing stubs. It supersedes the previous editions published in 2005, 1990, and 1983.Major changes in this edition include the method of measurement of sweep in poles and the reference to the ANSI photographic manual.Introduction:This Standard covers all commercial pole species used in Canada. Since there is an exchange of poles between Canada, Europe, and the United States, this Standard also includes the imported species of Scots pine and southern yellow pine and harmonizes some of the physical attributes with other countries' standards.During the development of the 2015 edition of this Standard, the Subcommittee agreed that published pole test data sets that are not included in Table A.1 of this Standard will be analyzed and, if deemed appropriate, the fibre stress and stiffness of the species in Table 3 will be updated accordingly in the next edition.Scope:1.1This 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.1.2This Standard does not cover requirements for wood poles intended for use in structures such as bridges and buildings.1.3This 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 CAN/CSA-O80 Series of Standards unless otherwise specified.1.4The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only. Tables 1 to 23 are written in yard/pound units and equivalent SI (metric) versions are provided in Annex E.1.5In this Standard, "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; and "may" is used to express an option or that which is permissible within the limits of the standard. 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.
