Safety colours and safety signs - Classification, performance and durability of safety signs (ISO 17398:2004, IDT)
This International Standard 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 this
International Standard 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.
This International Standard 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.
