30、document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. The main ch
31、anges incorporated in this revision are: a) Modification of the definitions to clarify better the different products glass beads antiskid aggregates and mixtures of the two; b) Update of the standard to the new technologies that allow lower defects on glass beads with diameter equal or bigger than 1
32、 mm; c) Addition of the essential characteristic of dangerous substances for glass beads and transparent antiskid aggregates in glass; d) Addition of test method to determine presence of dangerous substances; e) Addition of test method to determine glass beads and antiskid aggregates ratio in mixtur
33、es of the two; f) Modification of the order of paragraphs to comply to the template for European Standards; g) Addition of Clause 6 “Evaluation of conformity”; h) Modification of parts of Annex ZA to comply to the template for product standard. According to the CEN/CENELEC Internal Regulations, the
34、national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherla

BS EN 1423:2012EN 1423:2012 (E) 6 1 Scope This European Standard specifies the requirements applicable to glass beads, anti-skid aggregates, and the mixture of the two, which are ap
36、plied 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. 2 Normative references T

41、. In addition, 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: transparen
42、t antiskid 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

44、between bags and tins (25 kg to 50 kg) and bulk transport 4 Requirements 4.1 Glass beads 4.1.1 Surface treatments of glass beads 4.1.1.1 General Special coatings may be applied to the surface of the glass beads to enhance their properties. 4.1.1.2 Moisture proof coating Moisture proof coating is add
45、ed 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 penetra
46、te 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 coating is added to allow higher adhesion between the binder and the glass bea
47、ds when those are dropped on road marking materials. When the manufacturer declares the presence of an adhesion coating on the glass beads it shall be tested in accordance with a test method proposed by the manufacturer. The presence of the coating shall be declared as “Pass” or “Fail”. 4.1.1.5 Othe
48、r coatings When the manufacturer declares the presence of a coating, other than those in 4.1.1.2, 4.1.1.3 and 4.1.1.4, it shall be proved by testing the glass beads in accordance with a test method proposed by the manufacturer. The presence of the coating shall be declared as “Pass” or “Fail”. 4.1.2
49、 Visibility characteristics 4.1.2.1 Refractive index The refractive index or index of refraction of a substance is a measure of the speed of light in that substance. It is expressed as a ratio of the speed of light in vacuum relative to that in the considered medium. The refractive index n of glass beads, shall be determined in accordance with 5.3.2.1. It shall comply with the following classes: Class A n 1,5; Class B n 1,7; Class C n 1,9. BS EN 1423:2012EN 1423:2012 (E) 8 4.1.2.2 Maximum weighted percentage of defective glass beads
