BS EN 1463-1:2009 EN 1463-1:2009 (E) 3 Foreword This document (EN 1463-1:1997/A1:2009) has been prepared by Technical Committee CEN/TC 226 “ Road equipment” , the secretariat of which is held by AFNOR. This Amendment to the European Standard EN 1463-1:1997 shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2009, and conflicting national standards shall be withdrawn at the latest by September 2009. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This European Standard supersedes EN 1463-1:1997. The technical change incorporated in this revision is the Table ZA.1 in Annex ZA. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. ? BS EN 1463-1:2009 EN 1463-1:2009 (E) 4 Introduction In Mandate M/111, there is a clear requirement for durability in use. In order to meet this requirement, EN 1463-1 specifies, in Annex ZA Table ZA.1, the standard EN 1463-2 (Road test performance specifications). However, in the current Table ZA.1, the classes S0 and R0 (no performance determined) are included (just as a way to reflect the result of the mentioned durability test, which requires 1-year of road exposure for the applicant studs) and some notified bodies have interpreted this as meaning that it is not required to test to EN 1463-2 and consequently CE marks are being granted without durability being tested. However, in other cases, the mentioned test has been carried out; therefore, both types of road studs are now in the market granting a “ well different” class of CE-marking. In order to rectify this unsatisfactory situation it is proposed to amend the requirement for “ R” to become R1 to R4 - i.e. eliminating R0, which might have caused the confusion, and thus meaning that a road test has to be carried out and the requirement for durability is met. In addition, it is also proposed that the requirement for “ S” is deleted as this is not necessary to also have this to ensure durability is tested. ? BS EN 1463-1:2009 EN 1463-1:2009 (E) 5 1 Scope This European Standard specifies the initial performance requirements and laboratory test methods for retroreflecting road studs intended for use as permanent and temporary road marking materials. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 1463-2:2000, Road marking materials Retroreflecting road studs Part 2: Road test performance specifications ISO 10526, CIE standard illuminants for colorimetry ISO 10527, CIE standard colorimetric observers CIE publication No. 054.2-2001, Retroreflection: Definition and measurement IEC/CIE publication No. 017.4-1987, International lighting vocabulary, 4th ed. (Joint publication IEC/CIE) 3 Terms and definitions For the purposes of this European Standard, the terms and definitions in CIE publication 17.4:1987 apply together with the following. 3.1 retroreflecting road stud (called “road stud” in this standard) horizontal guiding device that reflects incident light by means of retroreflectors (see 3.2) in order to warn, guide or inform road users NOTE Retroreflecting road studs may be constructed in either one or more integral parts and may be bonded to, anchored within or embedded within the road surface. The retroreflecting portion may be unidirectional or bidirectional, depressible or non depressible. This device may be either permanent (type P) or temporary (type T). 3.2 retroreflector device which reverses the direction of visible light striking it and returns it along a path substantially parallel to its original path NOTE It may be made of glass (type 1), plastic (type 2) or plastic with an abrasion resistant surface (type 3). It may have a reflective coating at the back. 3.3 non depressible road stud substantially rigid road stud not designed to deform under the passage of traffic (type A) 3.4 depressible road stud road stud designed to have one or more parts which deform under traffic and recover to their original geometry after removal of the traffic load (type B) 3.5 bonded road stud road stud fixed to the road surface using an adhesive applied to the stud and/or to the road surface at the time of installation ? BS EN 1463-1:2009 EN 1463-1:2009 (E) 6 3.6 self-adhesive road stud road stud precoated with adhesive NOTE An adhesion enhancer (see 3.7) may be required under some climatic conditions. 3.7 adhesion enhancer additional coating on the load bearing surface of the road stud or on the road surface which improves the performance of the adhesive bond 3.8 anchored road stud road stud fixed to the road surface using an anchor or spigot NOTE The anchor(s) or spigot(s) may be an extension of the road stud body or a separate part(s) supplied for the purpose. The principal load bearing interface of the road stud and the road is between the surface of the road and the underside of the road stud. 3.9 embedded road stud road stud fixed into a prepared cavity of an appropriate dimension cut into the road surface NOTE The principal load bearing interface of the road stud and the road is between a downward facing surface of the road stud and an upward facing surface of the cavity. 4 Types of road stud Road studs are classified in this European Standard in accordance with Tables 1, 2 and 3. Table 1 - Classification of road studs by use Use Type Permanent road stud 1) P Temporary road stud 2) T 1) Provides night-time warning guidance and information to road users. 2) Provides daytime and night-time warning guidance and information to the road user by stimulating the use of three senses. It is received visually and can be heard and felt through the rumble effect. Temporary road studs are used only at road construction/maintenance sites. Table 2 - Classification of road studs by reflector Reflector Type Glass 1 Plastic 2 Plastic with abrasion resistant layer 3 NOTE The abrasion resistant layer is applied on the surface exposed to traffic. ?

If the road stud consists of two or more parts, each replaceable part shall be removable only with a tool recommended by the manufacturer. 5.2 Dimensions The height of that part of a road stud designed to be above the road surface shall be as follows: - class H 0 - no performance determined; - class H 1 - up to 18 mm; - class H 2 - from more than 18 mm to 20 mm; - class H 3 - from more than 20 mm to 25 mm. NOTE Class H 0 road studs are not intended to be subjected to traffic load. Maximum horizontal dimensions of that part of a road stud which is exposed to traffic after installation are classified as follows: - class HD 0 - no performance determined; - class HD 1 - in the direction of travel: length 250 mm, width 190 mm; - class HD 2 - in the direction of travel: length 320 mm, width 230 mm. NOTE Class HD 0 road studs are intended for use when other functional needs of the road stud are required (e.g. to be snowploughed). Minimum horizontal dimensions of that part of a temporary road stud which is exposed to traffic after installation are classified as follows: - class HDT 0 - no performance determined; - class HDT 1 - in the direction of travel: length 35 mm, width 84 mm; - class HDT 2 - in the direction of travel: length 75 mm, width 90 mm. 5.3 Night-time visibility 5.3.1 Photometric requirements 5.3.1.1 Permanent road stud When tested in accordance with Annex A, each retroreflective face of the road stud shall have a coefficient of luminous intensity (R) as classified (see Table 4) multiplied by the appropriate colour factor given in Table 5. - class PRP 0 - no performance determined; - class PRP 1 - not less than given in Table 4. ?
