Defines the requirements applicable to glass beads, anti-skid aggregates, and the mixture of the two, which are applied as drop-on materials on road markings products (i.e. paints, cold plastics and thermoplastics).

This European Standard specifies the requirements applicable to glass beads, anti-skid aggregates, and the mixture of the two, which are applied as drop-on materials on road markings products (i.e. paints, cold plastics and thermoplastics).

Glass beads and/or anti-skid aggregates, or their mixture, applied during the process of manufacturing other road marking products are not covered by this European Standard.
