European foreword

This document (EN 1463-2:2021) 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 November 2021, and conflicting national standards shall

be withdrawn at the latest by November 2021.

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 1463-2:2000.
The main changes with respect to the previous edition are listed below:

— This document has been prepared in order to achieve consistency with EN 1824 “Road marking

materials — Road trials”.

— To avoid redundancies, definitions which are stated in EN 1463-1:— have been removed from

Clause 3. For consistency, the Introduction has been also removed.

— Due to the fact that this document is a supporting document to harmonized EN 1463-1:— , the

content which refers to temporary products have been removed.

— In 4.5 “Road surface conditions” (former 4.1.5), concrete road surfaces have been added as a suitable

surface for carrying out the durability test.

— In 5.1 “Duration” (former 4.2.1), although it is fixed to one year, the-possibility of reducing it to 11

consecutive months (including, in any case, a complete summer and winter season) is also given, as

the number of available test sites in the EU is rather limited. Accordingly time needs to be planned

for removal and applying a new test.

— In 5.2 “Longitudinal application patterns” (former 4.2.2), drawings have been added to avoid any

misunderstanding.

— In 7.2 “Stage 1: daylight examination” (former 5.2), paragraph a) has been revised to avoid any

misunderstanding.

— In 7.3 Stage 2: night-time examination (former 5.3) process step a) “clean the retroreflectors” and a

note about cleaning has been added. While this just describes best practice, this information has been

added to avoid any misunderstanding.

— In 7.3 Stage 2: night-time examination (former 5.3) process step d) “if the total number of test studs

remaining is less than 43, the assessment shall be considered void” has been added, as a further

proceeding to stage 3 makes no sense under this condition.

— In 7.6 “Stage 5: testing selected test studs” (former 5.6), 7.6.3, a Note intended to open the possibility

to use portable equipment to carry out in field photometric measurements has been added.

— In Clause 8 “Individual test report” (former Clause 6) the classes S0-S3 have been removed, in

accordance with the changes introduced in EN 1463-1:— , and minimum test report requirements

have been added.

4 Test sites and conditions
4.1 General

Test sites shall be arranged at suitable locations that meet at least the requirements of 4.2 to 4.5. The test

results will depend on the weather, traffic and road surface conditions. These shall all be described in the

corresponding individual test report (see 8.2).
4.2 Test site design characteristics and location

Studs shall be tested on a road with two lanes in one direction (Figure 1). On this test site there shall be

no other than the national maximum speed limit.

Key

Figure 1 — Road with two lanes in one direction

Roads used for test sites shall be straight and flat, with the lowest longitudinal and transverse gradient

possible and free of singular points (such as traffic lights and intersections), substantial obstacles to

daylight, source of frequent dirt (such as quarries and field exits) and movement of tracked vehicles.

Any change of site conditions during the test period shall be avoided.

The lengthwise slope and any special circumstances shall be stated in the general report for the test site.

NOTE The in use specifications for “flat” refer to a maximum slope of 4 %.
4.3 Weather conditions

At the termination of a road trial, a weather report for the duration of the road trial shall be produced.

The weather report can be based on data from the nearest meteorological station and it can include data

obtained on the test site itself; it should include aspects of the weather of influence to the results of the

road trial.

Whether or not it is agreed between the participating parties that weather information is to be collected,

the weather report shall include as a minimum an account of temperature conditions during the testing

period.

NOTE Annex C is providing guidance for a simplified reporting method in accordance with the Köppen Climate

Classification. The weather report can include a monthly account of mean minimum and maximum day

temperatures, the cumulated precipitations in millimetres of water and the number of sand/grit scattering actions,

snow ploughing actions etc.
4.4 Traffic conditions

The annual average daily traffic (AADT) of test sites shall be at least 5 000 for the total carriageway in the

test direction and shall support between 10 % and 25 % heavy vehicles. A vehicle is considered a heavy

vehicle if its maximum gross mass is greater than 7 500 kg.

NOTE It is recommended to select the test site in a way that traffic can be re-directed for safe installation and

subsequent assessments.

Other special requirements (e.g. snow clearance, studded tyres) not included in the general minimum

requirements as specified in this Clause, but considered indispensable for some countries or special

applications, may be taken into account by the participating parties for the selection of the test site and

recorded in the report for the test site.

This document (prEN 1463-2:2019) has been prepared by Technical Committee CEN/TC 226 “Road

This document is currently submitted to the Formal Vote.
This document will supersede EN 1463-2:2000.

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 standard as a

harmonized standard under EU Regulation 305/2011.

— This standard have been fully harmonized with the structure of EN 1824 “Road marking materials”.

— To avoid redundancies with EN 1463-1 all definitions which are stated already in EN 1463 have

been removed from Clause 3.

— In 4.2 “Test site characteristics and location” (former 4.1.2 “General specifications for test sites) the

“in use” characteristic for “straight and flat” have been added as a reference.

— In 4.5 “Road surface conditions” (former 4.1.5) concrete road surfaces have been added as a

suitable surface. To avoid any misunderstandings the following Note have been added: “Durability

needs to be demonstrated at least on one road surface. Should the intended use of the road stud be

for more than one road surface, bonding tests on the other road surfaces are recommended”.

— In 5.1 “Duration” (former 4.2.1) the duration of road trials had been reduced from 1 year down to

11 month as the number of test sites are limited. Accordingly time needs to be planned for removal

and applying a new test.

— In 5.2 “Longitudinal application patterns” (former 4.2.2) drawings have been added to avoid any

misunderstanding.

— In 7.2 “Stage 1: daylight examination” (former 5.2) the paragraph a) have been revised to avoid any

Introduction

Retroreflecting road studs are horizontal guiding devices that reflect incident light by means of

retroreflectors in order to warn, guide or inform road users. They may be constructed in one or more

integral parts and may be bonded to, anchored within or embedded within the road surface.

Retroreflecting road studs are provided either as permanent or temporary devices for road users.

The initial performance requirements such as dimensions, night-time visibility, night-time colour,

daytime visibility etc. are specified in prEN 1463-1:2019.

In this part of the standard suitable methods are given for conducting road trials with the aim of

achieving comparability and reproducibility of test results.
1 Scope

This document describes a test method for carrying out road trials on retroreflecting road studs for use

in permanent applications. Specifications are given for test sites and for application patterns, and a

recommendation is given for the presentation of the results in the form of a test report.

Temporary road studs are covered in Annex D (informative).
