ISO 17398:2004根据预期使用环境、主要材料、光度特性、照明方式、固定方法和表面，规定了安全标志性能相关分类系统的要求。ISO 17398:2004中规定了性能标准和试验方法，以便在产品交付给买方时对与耐久性和预期使用寿命相关的性能进行表征和规定。 ISO 17398:2004不包括电源、其组件或电动元件。它也不包括照明组件的特性，但包括特定类型安全标志的光度特性。

ISO 17398:2004 specifies requirements for a performance-related classification system for safety signs according to expected service environment, principal materials, photometric properties, means of illumination, fixing methods and surface. Performance criteria and test methods are specified in ISO 17398:2004 so that properties related to durability and expected service life can be characterized and specified at the time of the product's delivery to the purchaser. ISO 17398:2004 does not cover electrical power supplies, their components or electrically powered elements. It also does not cover properties of illuminating components, but the photometric properties for the particular types of safety signs are covered.
