European foreword
This document (prEN 1463-2:2019) 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 1463-2:2000.
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
misunderstanding.
— Added in 7.3 Stage 2: night-time examination (former 5.3) process step a) “clean the
retroreflectors” and a note about cleaning. While this just describes best practice, this information
has been added to avoid any misunderstanding.
— Added 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” as a further
proceeding to stage 3 makes no sense under this condition.
— In Clause 8 “Result classification” (former Clause 6) the classes S0-S3 have been removed in
accordance with the changes introduced in EN 1463-1:2009.

— Added informative Annex C “Standardized documentation of weather conditions using the Köppen
classification”.
— As temporary road studs do not require CE mark, respective paragraphs have been moved to
Annex D (informative).
— Added informative Annex E “In-Situ testing of retroreflective properties using a portable (hand-
held) retroreflectometer”.
The Annexes A, B, C, D and E of this European standard are informative.

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).
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements 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.

3 Terms, definitions and types
For the purposes of this document, the terms and definitions given in prEN 1463-1:2019 and the
following apply.

4 Test sites and conditions
4.1 General
Test sites shall be arranged at suitable locations which meet at least the requirements of 4.1 to 4.5. The
test results will depend on the weather, traffic and road surface conditions. These shall all be described
in a general report for the test site.

4.2 Test site characteristics and location
Roads used for test sites shall be straight and flat (in use specifications refer to a maximum slope of
4 %), with the lowest longitudinal and transverse gradient possible and without singular points (such
as traffic lights and intersections), substantial obstacles to daylight, sources 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.
4.3 Weather conditions
At the termination of a road trial, it is recommended to produce a weather report for the duration of the
road trial. 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.
If 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 (informative) 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
Studs shall be tested on a dual carriageway road of two lanes in each direction so that traffic can be re-
directed for safe installation and subsequent assessments. On this test site there shall be no other than
the national maximum speed limit.
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 contain 10 % to 25 % heavy vehicles. A vehicle is considered a heavy vehicle
if its maximum gross mass is greater than 7 500 kg.
