1.1 本指南描述了在被单独磨耗层覆盖的建筑物占用空间上，用于广场甲板和步行街施工的完全粘附的组合式沥青防水系统的设计。 1.2 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.3 对本标准具有管辖权的委员会不知道其他组织发布的任何类似标准。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 本指南提供了在建筑桥面施工中选择构件和设计组合式沥青防水膜系统的信息和指南。如果目前的技术水平无法确定特定条件的标准，或有许多需要考虑的变量，则设计考虑的适用部分、章节 5 – 16 ，作为系统设计者选择的参考和指导。

1.1 This guide describes the design of fully adhered built-up bituminous membrane waterproofing systems for plaza deck and promenade construction over occupied spaces of buildings where covered by a separate wearing course. 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.3 The committee with jurisdiction over this standard is not aware of any comparable standards published by other organizations. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 This guide provides information and guidelines for the selection of components and the design of a built-up bituminous membrane waterproofing system in building deck construction. Where the state of the art is such that criteria for particular conditions are not established or have numerous variables that require consideration, applicable portions of design considerations, Sections 5 – 16 , serve as reference and guidance for selection by the designer of the system.
