This document specifies the material, mechanical and functional (fitness for purpose) requirements for warning devices with visual characteristics manufactured from plastics, intended to indicate the presence of cables and piping systems buried in ground when opening trenches and more generally during digging work. This document also specifies the test methods referred to in this document. This document is applicable to two types of visual warning devices: tapes (type 1) and meshes (type 2).
