序言这是CSA Z259的第三版。16、主动防坠落系统的设计。它取代了2015年和2004年出版的之前版本。它是CSA Z259系列个人防坠落系统部件标准的一部分。本版本的重大变化包括:a）术语“平均部署部队，FAvg”已被替换为“清障部署部队，FClr”。这一变化解决了一个常见错误，即认为坠落防护设备标签上的平均力适合用于计算。 提供了几种确定准确FClr的方法；b） 增加了一项要求，要求根据本标准未来版本的要求以及坠落防护设备和技术可能发生的变化，定期审查根据本标准设计的主动坠落防护系统；c） 提供了调整自由落体高度、工人重量/质量和个人能量吸收器展开力变化的间隙的方程式；d） 增加了确定用于锚定水平生命线的可变形锚的平均部署力的指南，以便将其建模为水平生命线能量吸收器。 本标准现在禁止在分析这些系统时使用静态分析；（ande）附件A中的评注已更新。CSA集团非常感谢加拿大政府负责职业健康和安全的部门为本版本的开发提供的财政和实物支持。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本标准规定了完整主动坠落的设计和性能要求- 保护系统，包括行程约束和垂直和水平防坠落系统。本标准适用于具有坠落防护系统设计专业知识的工程师。1.2本标准未规定根据适用CSA Z259设备标准要求制造的防坠落设备或系统的设计或性能要求。1.3本标准不得替代适用CSA Z259设备标准的坠落防护设备组件的测试和认证，除非该设备是为有限或现场定制的- 具体应用。1.4本标准不包括护栏和网等被动坠落防护系统的设计，除非此类被动系统也被设计为本标准涵盖的主动坠落防护系统的锚固和/或锚固连接器子系统。1.5本标准不包括定位系统的设计。1.6本标准不包括主动防坠落系统部件或固定点的结构强度和性能测定。然而，一旦知道强度和行为，它就建立了安全标准。 此类强度和性能由分析测试或工程方法、CSA集团或所用材料和结构系统的其他设计标准确定。1.7本标准不取代适用的职业安全和健康法规的要求。1.8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。1.9在本标准中，“应”用于表示要求，即:。 ，用户必须满足的条款，以符合标准；“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）来定义其应用。

PrefaceThis is the third edition of CSA Z259.16, Design of active fall-protection systems. It supersedes the previous editions published in 2015 and 2004. It is part of the CSA Z259 series of Standards for components of personal fall-arrest systems. Significant changes to this edition include the following:a) the term "average deployment force, FAvg" has been replaced with "clearance deployment force, FClr". This change addresses the common mistake of thinking that the average force on the label of fall protection equipment is suitable for use in calculations. Several ways of determining an accurate FClr are provided;b) a requirement has been added for periodic review of active fall protection systems designed to this Standard against the requirements of future editions of this standard as well as changes that might evolve in fall protection equipment and technologies;c) equations have been provided for adjusting clearances for changes to free fall height, worker weight/mass, and the deployment forces of personal energy absorbers;d) guidance has been added on determining the average deployment force of deformable anchors when used to anchor horizontal lifelines, so that they can be modelled as horizontal lifeline energy absorbers. This Standard now prohibits using static analysis when analyzing these systems; ande) the commentary in Annex A has been updated. CSA Group gratefully acknowledges the financial and in-kind support from the Canadian government departments responsible for occupational health and safety for the development of this edition. 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 the design and performance of complete active fall-protection systems, including travel-restraint and vertical and horizontal fall-arrest systems. This Standard is intended for engineers with expertise in designing fall-protection systems.1.2 This Standard does not specify design or performance requirements for fall-arrest equipment or systems that have been manufactured in accordance with the requirements of an applicable CSA Z259 equipment standard.1.3 This Standard is not to be used as a substitute for testing and certification of components of fall-protection equipment for which there is an applicable CSA Z259 equipment standard, unless the device is custom engineered for limited or site-specific applications.1.4 This Standard does not cover the design of passive fall-protection systems such as guardrails and nets, except where such passive systems are also designed to serve as anchorage and/or anchorage connector subsystems for active fall-protection systems covered by this Standard.1.5 This Standard does not cover the design of positioning systems.1.6 This Standard does not cover the determination of structural strength and behaviour of components or anchorages of active fall-protection systems. It does, however, establish the safety criteria once the strengths and behaviours are known. Such strengths and behaviours are determined by analytical testing or engineering methods and by CSA Group or other design Standards for the materials and structural systems being used.1.7 This Standard does not supersede the requirements of applicable occupational safety and health regulations.1.8 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.1.9 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 (nonmandatory) to define their application.
