1.1 这些测试方法涵盖了测试永久性栏杆系统、防护装置和栏杆玻璃性能时应遵循的程序，包括安装在装配、商业、教育、工业、机构、体育场馆、娱乐场所的栏杆和旋转门等部件或其他形式的所需护栏开口保护，以及住宅建筑和其他结构，如塔楼或高架平台。 1.2 这些试验方法适用于以玻璃或其他玻璃材料为主要结构部件或填充板（包括旋转门和其他形式的护栏保护）的栏杆、防护装置和栏杆系统。 1.3 这些试验方法可用于确定具有玻璃或其他玻璃材料的永久性栏杆、防护装置和栏杆（包括部件）是否符合性能规范、规范、规范和标准的要求。 1.4 具体而言，这些试验方法涵盖了确定栏杆系统、防护装置和栏杆的静态强度、冲击性能和破坏后特性的程序，包括在固定在混凝土、砌体、木材、金属和相关产品上的单面、双面、三面和四面支撑系统中安装玻璃或其他玻璃材料的组件。 1.5 在这些试验方法中，未考虑因不利环境或使用条件而导致的栏杆、防护装置或栏杆系统或其连接件和紧固件的任何可能劣化。可能需要进行涵盖这一方面的特殊测试。 1.6 这些试验方法仅限于本文所述负载和抗冲击性的应用。 根据适用规范、规范、规范和标准，当栏杆系统、防护装置或栏杆承受均布荷载时，应通过计算确定此类荷载对构件应力的影响，并测试相应的集中荷载和线性荷载。如果计算能够提供所需的信息，则可以使用测试进行验证。 1.7 这些试验方法涉及由导轨、防护装置或栏杆（或两者）支撑的玻璃或其他玻璃材料在单面、双面、三面和四边支撑系统中通过在冲击或玻璃破碎后留在设计框架系统中继续发挥屏障功能的能力。 这些试验方法不涉及玻璃或玻璃栏杆、防护装置和栏杆或车辆防护装置的结构限制，除非在人行道区域。 1.8 以国际单位制表示的数值应视为标准值。国际单位制后括号中给出的值仅供参考，不被视为标准值。本文引用的参考文件中包含的某些值可以用英寸-磅单位表示，并且必须由用户进行转换。 1.9 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。 1.10 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。

1.1 These test methods cover procedures to be followed in testing the performance of glazing in permanent railing systems, guards and balustrades including components such as rails and swing gates or other forms of required guardrail opening protection installed in and for assembly, commercial, educational, industrial, institutional, stadiums, recreational, and residential buildings and other structures such as towers or elevated platforms. 1.2 These test methods are applicable to such railing, guard, and balustrade systems having glass or other glazing materials as the major structural component or the infill panel including swing gates and other forms of guardrail protection. 1.3 These test methods can be used to determine whether permanent rails, guards and balustrades including components, having glass or other glazing material comply with requirements of performance specifications, codes, norms, and standards. 1.4 Specifically, these test methods cover procedures for determining the static strength, impact performance, and post-breakage characteristics of railing systems, guards, and balustrades, including a component with glass or other glazing material installed in one, two, three and four-side support systems fastened to concrete, masonry, wood, metal, and related products. 1.5 No consideration is given in these test methods to any possible deterioration of the railing, guard, or balustrade system or their connections and fasteners as resulting from adverse environmental or in-service conditions. The performance of special tests covering this aspect may be desirable. 1.6 These test methods are limited to the application of loads and impact resistance described herein. Whenever uniformly distributed loads are to be resisted by a railing system, guard, or balustrade in accordance with governing specifications, codes, norms, and standards, the effects of such loads on the member stresses shall be determined by calculation and the corresponding concentrated and linear loads shall be tested. Should computations make it possible to provide the needed information, testing can be employed for verification. 1.7 These test methods address the capability of glass or other glazing material supported by rails, guards, or balustrades, or both, in one, two, three, and four-sided support systems to continue in their function as a barrier by remaining in the designed framing system after impact or glazing breakage. These test methods do not address structural limitation of glazed or glass rails, guards, and balustrades or vehicular guards except when in the area of a pedestrian walkway. 1.8 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard. Certain values contained in reference documents cited and quoted herein may be stated in inch-pound units and must be converted by the user. 1.9 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. 1.10 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.
