Overview

EN 1463-1:2021 - published by CEN - is the European standard for road marking materials focused on retroreflecting road studs. It defines initial performance requirements for permanent studs used for lane delineation and guidance in circulation areas. The standard covers non-depressible (Type A) and depressible (Type B) studs with reflectors made of glass (Type 1), plastic (Type 2) or plastic with an abrasion-resistant layer (Type 3). Colours covered include white, yellow, amber, red and green. Excluded are non‑retroreflective studs and temporary road studs.

Key topics and technical requirements

• Night-time visibility: Specifies photometric performance expressed as the coefficient of luminous intensity (R). Measurements use defined observation and entrance angles (observation α = 0.3°, 1°, 2°; entrance β first axis = 0°, second axis = ±5°, ±10°, ±15°). Minimum R thresholds vary by reflector type and colour (see Table 3 of EN 1463-1:2021).
• Colour / chromaticity: Retroreflected chromaticity coordinates (x,y) are defined and must be measured per ISO/CIE colorimetry methods (ISO/CIE 11664-1:2019, ISO 11664-2:2007) using a 2° observer; accepted colour regions are given in the standard.
• Testing methods: Photometric testing (Annex A) and chromaticity testing (Annex B) detail lab measurement procedures, sampling and how results are expressed.
• Durability linkage: Initial performance links to durability assessment in EN 1463-2:2021; retained R after road testing is classified per EN 1463-2.
• Assessment & AVCP: Includes provisions for Assessment and Verification of Constancy of Performance (AVCP), factory production control (FPC), initial inspection and continuous surveillance - essential for CE marking where applicable.
• Terminology & designations: Clear definitions for “road stud”, “retroreflector”, bonded/anchored/embedded installation types and Type designations.

Practical applications and users

Who uses EN 1463-1:2021:

• Road authorities and highway engineers specifying permanent road marking products.
• Manufacturers of retroreflecting road studs for product design, quality control and compliance.
• Testing laboratories performing photometric and colourimetric verification.
• Procurement teams requiring objective acceptance criteria for contracts.
• Installers and maintenance teams selecting studs for different traffic and wear conditions.

Practical value:

• Ensures consistent night-time visibility performance across products.
• Helps select appropriate reflector material (glass/plastic/abrasion layer) and design (depressible vs non‑depressible) for site conditions.
• Provides standardized test and quality assurance procedures to support procurement, CE marking and longevity planning.

Related standards

• EN 1463-2:2021 - Road test performance specifications and durability classification.
• ISO/CIE 11664 series and CIE documents for colorimetry and retroreflection measurement.
• Refer to Annex ZA of EN 1463-1:2021 for relationships with EU Construction Product Regulation (where applicable).

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.
