EN 1423:2012+ AC:2013 (E) DIN EN 1423:2013-036 1 Scope This European Standard specifies the requirements applicable to glass beads, anti-skid aggregates, and the mixture of the two, which are applied as dr
40、op-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. 2 Normative references The followin

44、 markings by retroreflecting the incident headlight beams of a vehicle towards the driver NOTE This product is defined by five characteristics: refractive index, maximum weighted percentage of defective glass beads, granulometry, content of dangerous substances and resistance to chemicals. In additi
45、on, surface treatment with its intended use need to be declared by manufacturer (if any). 3.1.2 antiskid aggregate hard grain of natural or artificial origin, used to provide antiskid qualities for the road markings NOTE This product is defined by the following characteristics: transparent antiskid
46、aggregates: granulometry, resistance to fragmentation (friability); in addition, for transparent antiskid aggregates in glass, content of dangerous substances; non-transparent antiskid aggregate granulometry, resistance to fragmentation (friability) chromaticity co-ordinates and luminance factor. 3.

49、dded to avoid that the glass bead absorb air humidity. When tested in accordance with 5.3.1.1, the presence of moisture proof coating shall be declared as Pass” or “Fail”. 4.1.1.3 Floatation coating Floatation coating is added to glass beads mainly to allow to the beads to float (and so do not penetrate too much inside) when dropped on road marking materials in liquid phase. When tested in accordance with 5.3.1.2 the presence of floatation coating shall be declared as Pass” or “Fail”. 4.1.1.4 Adhesion coating Adhesion coatin
