GB/T 23809-2009 in English

《GB/T 23809-2009应急导向系统 设置原则与要求》由TC59（全国图形符号标准化技术委员会）归口，主管部门为国家标准化管理委员会。
本标准规定了公共建筑物内应急导向系统(safetywayguidancesystems,SWGS)的规划、设计和设置的原则与要求。
本标准适用于公共建筑物内SWGS中电光源要素和磷光要素的设计与设置,也适用于根据SWGS的使用环境、材料、设计、安装和维护来确定SWGS中的不同要素。
本标准不适用于触摸式和听觉类应急设施的设计与设置,也不适用于应急照明系统的设计和设置
(尤其是疏散路线照明的设计和应用),除非用于疏散路线上应急设备或疏散路线上特征位置(如安全出口或楼梯)的照明设计。
本标准不适用于水路和海运中船只的SWGS的设计和设置。

This standard describes the planning, design as well as setting principles and requirements of a safety way guidance system (SWGS) in public building.
This standard is not only applicable to design and arrangement of electric light source element and phosphorescent light element of SWGS in public building but also applicable to the situation that different SWGS elements are determined according to SWGS service environment, materials, design, installation and maintenance.
This standard also does not include the special considerations of possible tactile or audible emergency facilities of SWGS, nor does it include requirements concerning the emergency escape route lighting, especially the design and application of emergency escape route lighting, unless illumination is used to mark safety equipment or special features of the escape route like the emergency exit doors or stairs.
This standard is not applicable to SWGS design and arrangement of ships through waterway and sea transportation.
