European foreword
This document (EN 1463-1:2021) has been prepared by Technical Committee CEN/TC 226 “Road
equipment”, the secretariat of which is held by AFNOR.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by June 2022, and conflicting national standards shall be
withdrawn at the latest by September 2023.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 1463-1:2009.
This document has been prepared under a Standardization Request given to CEN by the European
Commission and the European Free Trade Association.
For relationship with EU Directive(s) / Regulation(s), see informative Annex ZA, which is an integral part
of this document.
The main changes with respect to the previous edition are listed below:
— To adapt the structure of the standard to the new CEN instructions for candidate harmonized
standards for construction products, the terminology and the Annex ZA have been adapted to CEN
guidance and template.
— All content that refers to temporary products and to none of the mandated characteristics has been
eliminated (deletion of content related to Temporary Road Studs and in use characteristics
“Dimensions”).
— Clause 6 “Assessment and verification of constancy of performance — AVCP” has been added.
— Former Clause 4 “type-of road stud” has been moved to Clause 3 “Terms, definitions, symbols, units
and abbreviated terms” under new subclause 3.10.
— Former Clause 5 “Performance Requirements” can be found in this standard under Clause 4
“Characteristics”.
— Subclause 4.1.1 “General explanation to angles” has been added to Clause 4 “Product characteristics”
(former Clause 5 “Performance Requirements”) to avoid any misinterpretation.
— Former Tables 4 and 5, in former subclause 5.3.1.1, have been merged as specified in that subclause
(see new Table 3 in 4.1.2.1) in order to make the interpretation of the threshold values corresponding
to that characteristic easier, and subsequently avoid potential mistakes. Therefore, threshold levels
specified for each type (1, 2 and 3) of road studs and colour specified in new Table 3 correspond to
those given in the previous version of EN 1463-1.
— Former subclause 5.3.1 “Photometric requirements” can be found in this standard under 4.1.2.1
“Coefficient of luminous intensity (R)”.
— Former subclause 5.3.2 “Colorimetric requirements” can be found in this standard under 4.1.2.2
Chromaticity co-ordinates (x,y).
— Subclause 4.2 “Durability of retro-reflectivity” has been added to give a clear link to EN 1463-2:2021.
Notice that according to the answer to Mandate M/111 (CEN reference doc N 1318 dated June 2013)
accepted by the European Commission, only Durability of retro-reflectivity expressed as coefficient
of luminous intensity (R) is considered relevant.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations 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, Netherlands, Norway, Poland, Portugal, Republic of North
Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United
Kingdom.
1 Scope
This document specifies the product characteristics, laboratory test methods, the way of expressing
results and the relevant procedures for assessment and verification of the constancy of performance for
retroreflecting road studs, non depressible and depressible by design (designated as Type A and B,
respectively) and which reflectors are made of glass, plastic or plastic with abrasion resistance layer
(designated as Type 1, 2 and 3, respectively), to be used for permanent road markings, and delineation
purposes, in circulation areas.
This document covers retroreflecting road studs (types - 1, 2, 3 - A, B) of white, yellow, amber, red and
green colour of their reflectors.
This document does not cover:
— non-retroreflective road studs;
— temporary retroreflective road studs.

3 Terms, definitions, symbols, units and abbreviated terms
For the purposes of this document, the following terms and definitions apply.
3.1
retroreflecting road stud
horizontal guiding device that reflects incident light by means of retroreflectors (see 3.2) in order to warn,
guide or inform road users
Note 1 to entry: Retroreflecting road stud called “road stud” in this document.
Note 2 to entry: Retroreflecting road stud may be constructed in either one or more integral parts and may be
bonded to, anchored within or embedded within the road surface. The body is typically manufactured with plastic
polymers, although solid glass is also used. The retroreflecting portion may be unidirectional or bidirectional,
depressible or non depressible.
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 1 to entry: 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
3.6
self-adhesive road stud
road stud pre-coated with adhesive
Note 1 to entry: 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 1 to entry: 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 1 to entry: 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.
