European foreword

This document (prEN 1463-1:2019) has been prepared by Technical Committee CEN/TC 226 “Road

equipment”, the secretariat of which is held by AFNOR.
This document is currently submitted to the Formal Vote.
This document will supersede EN 1463-1:2009.

This document has been prepared under a standardization given to CEN/CENELEC by the European

Commission and the European Free Trade Association, and supports basic work requirements of

Regulation (EU) Nr. 305/2011.
The main changes with respect to the previous edition are listed below:

— To adapt the structure of the standard to the new CEN rules when applying this document as a

harmonized standard under EU Regulation 305/2011. The wording and the Annex ZA have been

adapted to the CPR, following document TF N 687 rev1.

— The information from former Clause 3 “Terms and definitions” and Clause 4 ”Types of road stud”

have been integrated into Clause 3 “Terms, definitions and types”.

— The information from former Clause 5 “Performance requirements” have been restructured in the

Clause 4 “Performance characteristics and assessment methods” and clearly differentiates now

between “Essential characteristics” (i.e. those included in document: CEN/TC 226 N 1318) and

others grouped under the headline “In use characteristics”.
— Testing, assessment and sampling methods are listed in now Clause 5.

— Added Clause 6 – Assessment and verification of constancy of performance – AVCP, drafted

following document TF N 548 Rev1.

— Removed former Clause 7 ”Marking” as sufficient guidance is given in CPR and DoP.

— Drawings have been added in Clause 4 “Performance characteristics and assessment methods” to

avoid any misinterpretation.
— Added subclause 4.3 “Durability” to give a clear link to EN 1463-2.

— Added blue colour retroreflecting road studs in accordance with national standards.

— As temporary road studs do not require CE mark, respective paragraphs have been moved to

Annex E (informative).

Introduction

The development of this document has been prompted by the appearance of road studs which contain

an active element which emits light instead of, or as well as, reflecting light from headlights.

Road studs fulfil a very important function in providing guidance to drivers in conditions of darkness as

well as wet weather and poor visibility.

Retroreflective road studs are frequently used to supplement longitudinal road markings. They depend

for their brightness on the light from a vehicle's head lamps being reflected back towards the source.

Road studs may be permanent or temporary, and use a glass or plastic reflector, or a plastic reflector

with an abrasion resistant protective coating and fulfil several different photometric performance

requirements depending on the stud type. Their bodies are typically manufactured with plastic

polymers, although fully tempered solid glass (also defined as “safety glass”) are also used.

Road studs may also be depressible or non-depressible. In the former, the stud is mounted in a base unit

which is embedded into the carriageway. It is designed in such a way that a passing vehicle depresses

the stud thus wiping the reflectors clean by a “squeegee” action. Non-depressible studs with rigid

retroreflectors can be surface bonded or anchored using suitable adhesives, or embedded into the

carriageway using a base unit.
