FprEN 1790:2011 (E) 4 Introduction A particular category of road marking materials, used for horizontal signalization, are preformed, i.e. manufactured products in sheet form, ready for use on the road. They can be applied by means of adhesives, pressure or heat, with or without the use of a primer. Preformed road marking materials can be linear, in pieces of a certain length or in rolls. They can also be cut out in the form of symbols or signs or parts of them, making it possible to assemble them on the road to achieve the desired shape. Preformed road marking materials can be designed for use as permanent or temporary road markings. In both cases they can be applied with a view to later removal and therefore the specific property of "removability" can be required. Preformed road marking products are defined as Tape, preformed Cold Plastic road marking or preformed Thermoplastic road marking with or without drop-on materials. Except for Thermoplastic road markings with drop-on materials, all the other type of products are fully finished during manufacturing and do not change significantly their properties during application. They are completely covered by this standard. Thermoplastic road markings with drop-on materials need the addition of drop-on materials during application on the road and therefore they are in some way similar to thermoplastic products covered by FprEN 1871. This standard provides all the relevant information and cross references to FprEN 1871 in order to cover this kind of products. kSIST FprEN 1790:2011
FprEN 1790:2011 (E) 5 1 Scope The construction products covered and specified on this European Standard are white and yellow, removable or non-removable, preformed road marking materials, under the form of tape, cold plastic, thermoplastics with or without drop-on materials, to be used for permanent and/or temporary road markings in circulation areas. Other products and colours intended for road markings are not covered in this European Standard
This document gives also specifications for the evaluation of conformity for white and yellow, removable or non-removable, preformed road materials under the form of tape, cold plastic, thermoplastics with or without drop-on materials to be used for permanent and/or temporary road markings in circulation areas including type testing and factory production control. This European Standard also includes an Annex ZA for tapes, preformed cold plastic road marking and thermoplastic road marking without drop-on materials with the clauses addressing the provisions of the EU Construction Product Directive for permanent road marking. For preformed Thermoplastic road marking with drop-on materials, Annex ZA of FprEN 1871:2011 applies. 2 Normative references The following referenced documents are indispensable for the application of this document.

Additional materials to those described in 3.1 to 3.3 can include, if recommended by the manufacturer, primers which are liquid products which may contain solids and liquid additives suspended in an organic solvent or in water. The solids comprise inorganic and/or organic fillers, pigments and additives. The content of volatile organic solvents is not limited.
Primers are used to precoat road surfaces before the road marking system is applied. They improve the adhesion of the road marking and protect against disintegration, discolouring, etc. caused by incompatible compounds in the road surface. 4 Requirements 4.1 Tape, Preformed Cold Plastic Road Marking and Preformed Thermoplastic Road Marking without drop-on Materials 4.1.1 General The requirements are meant as characteristics of the materials as fully finished products. They are therefore intended as laboratory requirements. 4.1.2 Reflection in daylight or under road lighting (day-time visibility)
It represents the brightness of a road marking as seen by driver’s vehicles in typical or average daylight or under road lighting. It shall be measured either by the coefficient of luminance under diffuse illumination (Qd), expressed in mcd·m-2·lx-1 or by the luminance factor (). a) When luminance coefficient under diffuse illumination Qd is measured, the preformed road marking material is tested in accordance to 5.2.1 a) and shall comply with classes Q1 to Q5 of Table 1 of EN 1436:2007+A1:2008

4.1.3 Retroreflection under vehicle headlamp illumination (night-time visibility).
It represents the brightness of a road marking as seen by driver’s vehicles under the illumination by the driver’s own headlamp. The result is expressed by the coefficient of retroreflected luminance in mcd·m-2·lx-1. The coefficient of retroreflected luminance on dry conditions changes during wetness or during rain. Retroreflected luminance during wetness or during rain only applies for road markings type II. a) When preformed road marking material is tested on dry conditions, in accordance to 5.2.2 a), the coefficient of the retroreflected luminance RL shall comply with classes R1 to R5 of Table 3 of EN 1436:2007+A1:2008. b) When preformed road marking material is tested during wetness in accordance to 5.2.2 b), the coefficient of the retroreflected luminance RL shall comply with classes RW1 to RW6 of Table 4 of EN 1436:2007+A1:2008. kSIST FprEN 1790:2011

When a yellow preformed road marking is tested in accordance to 5.2.3, the x, y chromaticity co-ordinates shall lie within the region Y2 defined by the corner points given in Table 6 of EN 1436:2007+A1:2008 for yellow road markings. 4.1.5 Skid resistance
It represents the energy loss caused by the friction of a rubber slider over a specified length of a road marking surface in wet conditions. The result is expressed in SRT (Skid Resistance Tester) units. Measured on samples in the laboratory according to 5.2.4, the skid resistance of preformed materials shall be in accordance with classes S1 to S5 of Table 7 of EN 1436:2007+A1:2008. In the case of road trial with studded tyres class P0 applies. 4.1.6 Removability
Removability, as defined in 3.2, shall be tested in order to evaluate if the preformed road marking material is entirely removable without leaving permanent marks that could confuse the road user during the different weather conditions. The removability of preformed road markings cannot be determined in the laboratory and shall therefore be tested on the road, in accordance with 5.2.5. 4.1.7 Resistance to UV exposure
UV resistance shall be checked in accordance with 5.2.6. The chromaticity co-ordinates of preformed materials after UV exposure shall comply with the region for white road markings of Table 6 and with region Y2 for yellow road markings of Table 6 in EN 1436:2007+A1:2008, respectively for white and yellow preformed road marking.

The manufacturer shall always retain the overall control and shall have the necessary means to take responsibility for the product. 6.2 Initial type testing and Type Testing 6.2.1 General Initial type testing and type testing shall be performed to demonstrate compliance with this European standard, All essential characteristics for which the manufacturer declares performances are subject to Initial Type Testing. In addition, the need to perform Type Tests applies to all other characteristics included in a standard when the manufacturer claims compliance, unless the standard gives provisions (e.g. use of previously existing data, CWFT and conventionally accepted performance) for declaring performances without performing tests. Tests previously performed in accordance with the provisions of this standard, may be taken into account provided that they were made to the same or a more rigorous test method, under the same system of attestation of conformity on the same product or products of similar design, construction and functionality, such that the results are applicable to the product in question. NOTE 1 Same system of attestation of conformity means testing by an independent third party under the responsibility of a product certification body. For the purposes of testing, the manufacturer's products may be grouped into families, where it is considered that the results for one or more characteristics from any one product within the family are representative for that same characteristics for all products within that same family (a product may be in different families for different characteristics).
NOTE 2 Products may be in different families for different characteristics. NOTE 3 Reference to the test method standards should be made to allow the selection of a suitable representative sample. kSIST FprEN 1790:2011
FprEN 1790:2011 (E) 12 Therefore Type Tests or Initial Type Testing shall be performed for all characteristics included in the standard for which the manufacturer declares performances, including that Identification is performed as in Annex A for Tape, Preformed Cold Plastic road marking and Preformed Thermoplastic road marking without drop-on materials and performed as in FprEN 12802 for Preformed Thermoplastic road marking with
drop-on materials: at the beginning of the production of a new or modified preformed road marking materials,
at the beginning of a new or modified method of production (where this may affect the stated properties); or they shall be repeated for the appropriate characteristic(s), whenever a change occurs in the preformed road marking materials, in the raw material or in the supplier of the components, or in the production process (subject to the definition of a family), which would affect significantly one or more of the characteristics. Where components are used whose characteristics have already been determined, by the component manufacturer, on the basis of compliance with other product standards, these characteristics need not be re-assessed. The specifications of these components shall be documented, as shall be included in the inspection scheme for ensuring their compliance. Preformed road marking materials marked in accordance with appropriate harmonised European specifications may be presumed to have the performances stated with the that marking, although this does not replace the responsibility of the preformed road marking materials designer to ensure that the preformed road marking materials as a whole assembly is correctly designed and its components have the necessary performance values to meet the design. 6.2.2 Test samples, testing and compliance criteria The number of samples of Tape, Preformed Cold Plastic road marking and Preformed Thermoplastic road marking without drop-on materials to be tested/assessed for Initial Type testing and Type Testing shall be in accordance with Table 3.
