European foreword
This document (EN 12767:2019/prA1:2024) 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 CEN Enquiry.
1 Modifications to the European foreword
th
Replace the whole 5 paragraph with the following one:
"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 level 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 sensitivities 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 product ranges (former 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 levels.".
th
Replace the whole 7 paragraph with the following one:
"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, 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 sensitivity (MD) and risk of roof indentation
(1).".
2 Modifications to the Introduction
nd
Replace the 2 paragraph with the following:
"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. Passive safety for vulnerable road users, e.g. motorcyclists, is not
covered by this document.”.
th
Replace the 4 paragraph with the following:
"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 product ranges and for modified products (called “changed
versions”).".
th
Replace the 5 paragraph with the following:
"This document considers:
— two kinds of test inputs:
— three speed levels (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 levels (from A to E);
— two modes of collapse for support structures (Separation mode (SE) and No separation collapse
mode (NS));
— three direction sensitivities (single-directional (SD), bi-directional (BD) and multi-directional
(MD));
— two classes of risk of roof indentation (0 or 1).".
3 Modification to Clause 2, “Normative references”
Add the following reference to the list:
“EN 16303 , Road restraint systems - Validation and verification process for the use of virtual testing in
crash testing against vehicle restraint system”.
4 Modifications to Clause 3, “Terms and definitions”
Replace term 3.20 with the following:
"3.20
ballast
mass added to a test vehicle, including measurement and instrumentation, to simulate cargo and/or to
achieve desired test mass".
Under term 3.26 object length, replace the Note 1 to entry with the following:
"Note 1 to entry: For lighting columns, the object length is the height above ground level (h) plus half of the longest
horizontal bracket projection (w) in case of one or two bracket in top of the support structure. h and w are defined
by EN 40-2.".
Under review
5 Modifications to Clause 5, “General test parameters”
st
In 5.1, replace the 1 paragraph with the following:
"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 the impact point 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.".
rd
In 5.2.1, replace the 3 paragraph with the following:
"Within one product range, the same backfill type shall be used for all tests.".
st
In 5.2.2, replace the 1 paragraph with the following:
"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 grading curve supplied by the manufacturer of the product to
be tested and included in the test report (grading shall be in accordance with EN 13285).".
In 5.2.3, replace the NOTE with the following:
"NOTE The backfill can be locally damaged in the impact area as a result of the impact test.".
6 Modification to Clause 6, “General test item parameters”
th
In 6.2.1, replace the 4 paragraph with the following:
"In those cases where several versions of a product are based on the same construction principle, the
manufacturer selects an item to be a parent member. Annex G gives explanations on how to choose the
other products in the range.".
7 Modification to Clause 7, “Test method”
Replace the whole subclause 7.4 with the following:
“7.4 Impact speed
"The manufacturer shall select the speed level to which the support structure will be tested from Table 2.
The speed level identifies the impact speed in the high-speed test.
Table 2 — Support structure speed level
Speed level Impact speed Impact speed tolerance
km/h km/h
50 50 ±3
70 70 ±5
100 100 ±5
For any speed level, a low speed test shall also be carried out at 35 km/h ± 3 km/h. An additional 50 km/h
test can be necessary following the provision given in A.2.
The overall accuracy of the impact speed measurement shall be within ±2 % of the target impact speed.
The test vehicle impact speed shall be measured along the test vehicle approach path, no further than 6 m
before the impact point. The average impact speed shall be measured over a length of at least 1 m.".

Data evaluation
A.1 Performance class
The performance class of each tested support structure shall be expressed as a combination of speed
level, energy absorption category, occupant safety level, backfill type, collapse mode, direction sensitivity
given, and risk of roof indentation given by the parameters shown in Table A.1. The performance class
shall be expressed in the following format; speed level-energy absorption category-occupant safety level-
backfill type-collapse mode-direction sensitivity-risk of roof indentation, e.g. 100-HE-A-S-SE-MD-1, 70-
LE-B-R-SE-SD-0 and 100-HE-C-X-NS-MD-1.

The support structure shall successfully pass the test(s) described in this document, and shall meet the
general requirements given in A.2 to A.7.
The test vehicle shall not roll over (including rolling onto its side) within a 12 m radius of the impact
point.
Some standard metal tubes are deemed to comply with the requirements of this document, and their
performances classes are given in Annex K.
If not all variables are of interest for the specifier, the specifier can put NR (no requirement) for that
variable.
For products tested in accordance with previous versions of this standard, Annex L provides guidelines.
A.2 Evaluation of speed level
Support structures shall be classified according to speed level. Three speed levels are defined according
to the selected impact speed: 100 km/h, 70 km/h and 50 km/h.
In order to receive a speed level, the test item shall be tested at high speed (the speed level) and low
speed (35 km/h test). If the support structure is not activated in the low speed test, an additional test at
50 km/h shall be performed in speed levels 100 km/h and 70 km/h.
Activation means that one point of the support, situated in the lower 2,0 m of the support structure, has
a permanent displacement of more than 0,5 m. Rotation of the bracket or
