[中文适用范围]： 重要信息 — 本文档的电子文件包含被认为有助于正确理解文档的颜色。 因此，用户应考虑使用彩色打印机打印本文档。 ISO 3864 的这一部分规定了工作场所和公共区域使用的安全标志颜色的比色和光度要求以及测试方法。 它提供了 ISO 3864-1 中规定的指定安全色和对比色的色度和光度规范。 安全标志必须满足的物理要求主要与白天颜色和正常照明环境有关。 ISO 3864 的这一部分还包括同样在无光环境下工作的安全标志和磷光材料的比色要求和测试方法。 ISO 3864 的这一部分适用于需要解决与人员相关的安全问题的所有场所。 然而，它不适用于用于引导铁路、公路、河流、海上和空中交通的信号，并且一般来说，不适用于受可能不同监管的那些部门。 ISO 3864 本部分未规定逆向反射安全标志、与荧光或磷光材料结合的逆向反射材料或由放射源激活的发光安全标志的色度和光度特性。 [外文原描述]： ISO 3864-4:2011 establishes the colorimetric and photometric requirements and test methods for the colours of safety signs to be used in workplaces and public areas. It provides the colorimetric and photometric specifications for the named safety and contrast colours prescribed in ISO 3864­1. The physical requirements that safety signs have to meet are primarily related to daytime colour and normally lit environments. ISO 3864-4:2011 also includes the colorimetric requirements and test methods for safety signs and phosphorescent material which also operate in unlit environments. ISO 3864-4:2011 is applicable to all locations where safety issues related to people need to be addressed. However, it is not applicable to signalling used for guiding rail, road, river, maritime and air traffic and, generally speaking, to those sectors subject to a regulation that may differ. The colorimetric and photometric properties of retroreflective safety signs, retroreflective materials combined with fluorescent or phosphorescent materials, or luminous safety signs activated by a radioactive source are not specified in ISO 3864-4:2011.
