Security and resilience — Vehicle security barriers — Part 2: Application
This document gives guidance on the selection, installation and use of vehicle security barrier (VSBs) and describes the process of producing operational requirements (ORs). It also gives guidance on a design method for assessing the performance of a VSB. This document is applicable to end users, such as site owners and specifiers, of VSBs, where they are used to protect people in any public or private location from 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 components, see LPS 1175[53]. 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 (paving, cobblestone, granite, asphalt). It does not apply to guidance on design, the operational suitability of a VSB or other impact test methods.

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 document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use
of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed
patent rights in respect thereof. As of the date of publication of this document, ISO had not received
notice of (a) patent(s) which may be required to implement this document. However, implementers are
cautioned that this may not represent the latest information, which may be obtained from the patent
database available at www.iso.org/patents. ISO shall not be held responsible for identifying any or all
such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO’s adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

This document was prepared by Technical Committee ISO/TC 292, Security and resilience.
This first edition cancels and replaces IWA 14-2:2013, which has been technically revised.
The main changes are as follows:
— alignment with ISO 22343-1;
— updating of the document in light of changing threat and availability of tested vehicle security
barriers (VSBs), i.e. surface-placed and shallow mount systems;
— re-organization of the document for international readability.
A list of all parts in the ISO 22343 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Security and resilience — Vehicle security barriers —
Part 2:
Application
1 Scope
This document gives guidance on the selection, installation and use of vehicle security barrier (VSBs)
and describes the process of producing operational requirements (ORs).
It also gives guidance on a design method for assessing the performance of a VSB.
This document is applicable to end users, such as site owners and specifiers, of VSBs, where they are
used to protect people in any public or private location from 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
[53]
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 (paving, cobblestone, granite, asphalt).
It does not apply to guidance on design, the operational suitability of a VSB or other impact test methods.

4 Introduction to hostile vehicle mitigation
4.1 General
4.1.1 Vehicle-borne threats
Vehicle-borne threats can range from the use of a vehicle for vandalism to determined attacks by
adversaries (e.g. criminals and terrorists). The convenience, mobility and payload capacity of a vehicle
offers a tactical means to deliver multiple adversaries and weapons (e.g. an explosive device, firearms
or other hazardous payloads) closer to their target. Vehicles can also be used as a weapon: to drive into
people to cause injury and/or ram into infrastructure to disrupt services.
To conduct such attacks, hostile vehicles can be parked, manoeuvred or rammed into or out of a site, or
adversaries can use a deception or duress methodology.
Attacks on the VSB to enable access by the hostile vehicle without damaging the vehicle or occupants
can include:
a) physical: forcing/tampering with the VSB or the use of an explosive device;
b) electronic: accessing and manipulation of the VSB control system or interfaced platforms (e.g.
access control and building management systems).
A clear definition of the asset(s) (e.g. infrastructure and/or people) to be protected, the th
