1.1 本指南涵盖了用于安全应用的装饰性钢尖桩围栏系统设计中的材料和安装标准。适当的材料选择和系统安装布局可以大大增加渗透的难度；从而增加了入侵延迟时间。 1.2 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者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。 1.3 本指南不旨在为安全目的设置装饰性钢尖桩围栏系统的具体要求。 它打算涵盖与出于安全目的设计和建造装饰性钢尖桩围栏系统有关的考虑或选择。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ===意义和用途====== 4.1 装饰性钢尖桩围栏系统可以通过选择增加穿透难度并进而增加延迟时间的样式和配置来提供更高级别的安全性。 一些例子包括:增加围栏的高度，使用向外弯曲的装饰性尖桩样式在围栏的攻击侧形成女儿墙，以及减少垂直尖桩之间的间距。 4.2 装饰性钢尖桩围栏系统的安全加固可以通过添加围栏安全附件来实现（即，在顶部添加有刺铁丝；在围栏的顶部、侧面或底部添加有刺胶带；或沿顶部围栏添加有刺的栏杆），或通过附加安全围栏填充材料来实现（即，膨胀金属、带倒钩的胶带网、焊接钢丝网或链式迷你网织物）。需要时，可以插入板条或屏蔽板以限制可见性。 4.3 可以安装多条围栏线来创建隔离区，从而增强巡逻或视觉监控该区域的能力。 4.4 可以添加防撞击电缆系统，以防止车辆穿透受保护的周边。

1.1 This guide covers the material and installation standards for selection in the design of an ornamental steel picket fence system for security applications. The proper material selection and system installation and layout can substantially increase the difficulty to penetrate; thereby, increasing the intrusion delay time. 1.2 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. 1.3 This guide is not intended to set specific requirements for an ornamental steel picket fence system for security purposes. It intends to cover the considerations or options pertinent to the design and construction of ornamental steel picket fence systems for security purposes. 1.4 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 Ornamental steel picket fence systems can be designed to provide greater levels of security by selecting styles and configurations that increase the difficulty to penetrate and in turn increase delay time. Some examples include: increasing the height of the fence, using ornamental picket styles that curve outward to form a parapet on the attack side of the fence, and decreasing the spacing between vertical pickets. 4.2 Security hardening of ornamental steel picket fence systems can be achieved by adding fence security accessories (that is, barbed wire to the top; barbed tape to the top, side or bottom of the fence; or spiked railing supplements along the top rail) or by attaching supplemental security fence fill materials (that is, expanded metal, barbed tape mesh, welded wire mesh, or chain-link mini-mesh fabric). Slats or screening panels can be inserted to restrict visibility when required. 4.3 Multiple fence lines can be installed to create isolation zones that enhance the ability to patrol or visually monitor the area. 4.4 Anti-ram cable systems may be added to resist vehicle penetration into a protected perimeter.
