European foreword

This document (EN 12767:2019) has been prepared by Technical Committee CEN/TC 226 “Road

Equipment”, the secretariat of which is held by AFNOR.

This document shall be given the status of a national standard, either by publication of an identical text

or by endorsement, at the latest by February 2020, and conflicting national standards shall be withdrawn

at the latest by February 2020.

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 12767:2007.
The significant technical changes incorporated in this revision are:

— incorporation of the Regulation (EU) No 305/2011 of the European Parliament and of the Council of

9 March 2011 laying down harmonized conditions for the marketing of construction products and

repealing Council Directive 89/106/EEC terminology;

— introduction of a push-pull test to enable a comparison to be made between the backfills used in the

test and those on-site;

— harmonization of the boundary values for occupant safety (ASI and THIV) independent of the energy

absorption class;

— replacement of the occupant safety class by an alphanumeric character instead of a number to make

a clear distinction with the old (EN 12767:2007) approach. Now, NE-C, LE-C and HE-C have the same

occupant safety. The best occupant safety is achieved for A;

— introduction of collapse modes to classify if test items become detached or do not become detached;

— introduction of direction classes to take into account any sensitiveness to impact angle;

— improved test description, include installation manual and translation of roof deformation into a

measurable value, to reduce the influence of the vehicle structure on the test results;

— introduction of an extra test at 50 km/h for cases where the test-item is not activated at low speed.

An explanation of the definition of “activated” is also given;

— better rules for the determination of families (product families) based on the tested limit(s);

— introduction of a risk assessment approach, in line with the EN 1317-1:2010, for assessing changes

of a version, and the use of (for example) virtual testing in this;
— possibility to declare, under certain conditions, intermediate speed classes.

Most of the comments collected from all CEN members to the previous version of this norm are

implemented or solved. The definition and use of newer technologies has to be developed before

introduction into the standard.

Some added changes mentioned above are expressed in a new performance classification for the product.

This results in a longer description of the overall passive safety performance, but at the end, it gives a

clearer indication of product performance. For example, an old performance classification like “100, HE,

---------------------- Page: 6 ----------------------
SIST EN 12767:2019
EN 12767:2019 (E)

3” could be translated to “100-HE-C-S-SE-MD-1”. In this example, the last 4 sub-indications stands for

backfill type (S), collapse mode (SE), direction class (MD) and risk of roof indentation.

Translation of older tests to this new standard is possible when sufficient information is available in the

reports, photographs and videos of the tests.

The previous version of EN 12767 included test acceptance criteria – this is now, for convenience,

repeated in Annex A.

When this standard is used as a supporting standard for a product standard under CPR (e.g. sign

supports) relevant clauses of Annexes A, G and H are supposed to be copied inside the product standard,

and the product standard refers to the rest of this standard.

When this standard is used for testing constructions with no product standard the specifying authority is

supposed to refer to whole EN 12767, including Annexes A, G and H.

Annexes A, B, D, E, G, H, I, K, L, M of this document are normative, Annexes C, F, J are informative.

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.

Introduction

The severity of accidents for the occupant(s) of a vehicle is affected (in part) by the performance of the

support structures for items of road equipment under impact. Based on safety considerations, support

structures can be designed to behave in controlled ways to reduce the overall risk.

Passive safety is intended to reduce the severity of injury to vehicle occupants of a car in an impact with

support structures of road equipment.
This document has been developed in order to provide:
— test methods for determining impact safety performance; and
— methods to handle the data resulting from the impact tests;

— technical background about passive safety that can be used in the product standard.

The test procedure includes guidelines:

— for test item selection, test parameters, detailed test methods with different test conditions, the data

to record, and requirements for reporting;

— to assess the performance within families of product (called “product families”) and for modified

products (called “changed versions”).
This document considers:
— two kinds of test inputs:
— three speed classes (50, 70 and 100);
— three Backfill types (standard aggregates (S), special (X) and Rigid (R)).
— five kinds of test outcomes:

— three energy absorption classes: high energy absorbing (HE), low energy absorbing (LE) and

non-energy absorbing (NE);
— five occupant safety classes (from A to E);

— two modes of collapse for support structures (Separation mode (SE) and No separation collapse

mode (NS));

— three direction classes (single-directional (SD), bi-directional (BD) and multi-directional (MD));

— two classes of risk of roof indentation (0 or 1).

In order to help to evaluate the risk in case of a product modification, this document introduces Virtual

Testing through the definition of procedures for verification, validation, and development of numerical

models.

Based on the evaluation of the performance of each tested support structure, National and Local road

authorities will be able to specify the performance class of an item of road equipment support structure

in terms of the likely effect on the occupants of a vehicle in impact with the structure.

5 General test parameters
5.1 Test site

The test site shall be generally flat and have a level, hardened surface with a gradient not exceeding 2,5 %.

The area around the test item until 15 m behind shall be clear of standing water, ice or snow at the time

of the test. The test site shall be of sufficient size to enable the test vehicle to be accelerated up to the

required speed and controlled so that its approach to the test object is stable.

The test vehicle shall run on a levelled (no steps allowed) hardened or paved surface over the backfill

volume without influencing the movement of the test item.

NOTE For the purposes of this standard, the term “paved” is used only for an installation with asphalt, brick

slabs/pavers or a concrete surface.

Appropriate measures shall be taken in order to minimize dust generation from the test area and the test

vehicle during the impact test so that photographic records will not be obscured.

5.2 Backfill
5.2.1 General

The manufacturer shall select the type(s) of backfill to be used in the Type Tests from those given in

Table 1.
Table 1 — Backfill type
Backfill type Name
S Standard aggregates
X Special
R Rigid

The backfill at the test site shall be well known, repeatable and described thoroughly, either in the test

report or as a reference to well-known and widely accepted geotechnical references or pavement

properties.
Within one product family, the same backfill type shall be used for all tests.
The different backfill types are described in 5.2.2 and 5.2.3.

The backfill according to which the performance of the test item is determined is part of the performance

declaration (see Annex A).
5.2.2 Backfill type S and X

Backfill type S and X identify the use of backfill material in the backfill volume.

— Backfill type S grading shall be in accordance with B.3.

— Backfill type X shall be described by a sieving curve supplied by the manufacturer and included in

the test report (grading shall be in accordance with EN 13285).
The results of the push/pull test should be reported according to Annex C.

The minimum dimensions of the backfill volume, the positioning of the item in the volume and the

compaction of the backfill material shall comply with B.1 and B.2. The backfill volume shall not be frozen

at the time of test and shall be protected from rain before the impact test.
