序言这是CSA O112的第三版。9.结构木制品用粘合剂的评估（外部暴露）。它取代了2010年和2004年出版的前两个版本。与CSA O112系列中依赖CSA O112的其他标准不同。0对于其试验程序，本标准不限于特定类别的粘合剂，其试验程序是独立的。它也是评估胶粘剂在热条件下性能的少数标准之一，与防火木材组件中使用的结构木材产品在火灾期间可能遇到的热条件相对应。本版本的重大变更包括以下内容:-在第3条中增加了定义。本标准的使用者应注意，本标准仅适用于未经处理的木材。本标准的使用者完全有责任决定是否将其要求应用于处理过的木材。 本标准中的程序正在由负责制定本标准的技术委员会和小组委员会的成员继续制定。附件C中描述了正在开发的区域。这些区域包括开发粘结木构件的防火试验。本标准的制定符合加拿大标准委员会对加拿大国家标准的要求。CSA集团已将其作为加拿大国家标准发布。范围1。1本标准规定了用于外部应用的结构木制品中粘结实木材料的粘合剂的评估要求。注:有关结构木材粘合剂的外部暴露和其他水分暴露类别的更多信息，请参见附录C。1.2本标准规定了在潮湿和干燥条件下，评估粘合剂对a）压缩荷载引起的剪切的耐受性的要求； b） 在潮湿和干燥加速暴露期间发生分层；c）在高温、高湿度或高温和高湿度组合条件下，静态剪切载荷下的变形。1.3本标准不适用于拟用于地下、地面接触或海上服务应用的粘合剂。1.4本标准不用于评估木材化学处理对粘合剂性能的影响。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。1.6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。

PrefaceThis is the third edition of CSA O112.9, Evaluation of adhesives for structural wood products (exterior exposure). It supersedes the previous editions, published in 2010 and 2004.Unlike the other Standards in the CSA O112 Series, which rely on CSA O112.0 for their test procedures, this Standard is not restricted to a specific class of adhesives, and its test procedures are self-contained. It is also one of the few Standards that evaluate the performance of adhesives under thermal conditions corresponding to those that would be encountered during a fire by a structural wood product used in a fire-protected wood assembly.Significant changes to this edition include the following:-addition of definitions to Clause 3.Users of this Standard should note that it has been developed for untreated wood only. It is solely the responsibility of the users of this Standard to decide whether they wish to apply its requirements to treated wood.The procedures in this Standard are under continuing development by the members of the Technical Committee and the Subcommittee responsible for producing this Standard. The areas under development are described in Annex C. They include the development of a fire test for bonded wood members. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.Scope1.1 This Standard specifies requirements for evaluating adhesives used to bond solid wood materials in structural wood products designed for exterior applications. Note: See Annex C for additional information on exterior exposure and other moisture exposure categories for structural wood adhesives.1.2 This Standard specifies requirements for evaluating the resistance of adhesives to a) shear caused by compression loading, under both wet and dry conditions; b) delamination during accelerated exposure to wetting and drying; and c) deformation under static shear loading during exposure to heat, high humidity, or combined heat and high humidity.1.3 This Standard does not apply to adhesives intended for below-ground, ground-contact, or marine service applications.1.4 This Standard is not intended for the assessment of the effects of chemical treatments of wood on adhesive performance.1.5 In 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.1.6 The 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.
