  • Yellow for gas networks
  • Material : Polyolefins
  • Colorfastness: Resistance to blackening by ammonium sulfide
  • Resistance to microorganisms: According to EN ISO 846 standard
  • Mechanical tensile strength: Rr > 300 N
  • Excavation opening simulation: Visible element > 200 mm during excavation and digging

A warning device, a plastic mesh type, must be placed above each pipeline. This warning device is positioned 0.20 meters above the pipeline. It should be of the same color as the type of pipeline
