Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO
collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documentsdocument should be noted. This document was drafted in accordance

FINAL DRAFT INTERNATIONAL STANDARD ISO/FDIS 22343-1:2023 (E)

Security and resilience — Vehicle security barriers — Part 1:
Performance requirement, vehicle impact test method and
performance rating
1 Scope
This document specifies impact performance requirements for a vehicle security barrier (VSB) and a test
method for rating its performance when subjected to a single impact by a test vehicle not driven by a
human being. It is applicable to test methods for vehicle penetration distances not exceeding 25 m.
This document is applicable to all manufacturers and procurers of VSBs, where they are used to protect
people in any public or private location from the impact of vehicle attacks.
This document does not apply to the performance of a VSB or its control apparatus when subjected to:
— slow speed encroachment;
— slow speed nudging and ramming;
— blast explosion;
— ballistic impact;
— manual attack, with the aid of the vehicle (multiple impacts at slow speed);
— manual attack, with the aid of tools (excluding vehicles);
— electrical manipulation;
— attack on the control systems by any means.
NOTE 1 For manual attack, a variety of test methods exist. For assessing intruder resistance of building
[6]
components, see LPS 1175 .
NOTE 2 The VSB is designed and tested on the basis of:
a) vehicle type, mass and speed of the assessed vehicle-borne threat;
b) its geographical application (e.g. climate conditions);
c) intended site location (e.g. rigid or non-rigid soil / /finished surface).
It does not apply to guidance on design, the operational suitability of a VSB or other impact test methods.
NOTE 3 Guidance on the selection and specification of a VSB by type and operational suitability is given in
ISO 22343-2.

4 VSB performance requirement
When tested in accordance with the test method in Clause 6, the VSB shall affect the test vehicle by:
a) preventing it from advancing beyond the VSB datum line; or
b) redirecting the vehicle such that it remains on the non-protected side of the VSB; or
c) bringing it to a halt beyond the VSB datum line (vehicle penetration).
In the event of c), the impact of the test vehicle with the VSB shall render the vehicle immobile by:
— causing damage to the vehicle such that it is not able to progress under its own power;
— becoming entangled with the vehicle such that it is not able to progress under its own power; or
— catching, trapping, or lifting the vehicle such that it is not able to progress under its own power.
NOTE 1 Test data supporting the above are to be recorded within the report.
NOTE 2 Where vehicle penetration beyond the VSB datum line is greater than 25 m, a performance rating is not
awarded (see Clause 7).
