scope:

This part of IWA 14 specifies the essential impact performance requirement 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 also includes the following optional assessments that can be carried out as part of the vehicle impact test method:

a) pedestrian intruder access;

b) occupant injury. It does not cover the performance of a VSB or its control apparatus when subjected to:

- blast explosion;

- ballistic impact;

- manual attack, with the aid of tools (excluding vehicles); or

- electrical manipulation/attack of the access control system.

NOTE 1 For manual attack, a variety of test methods exist. For assessing intruder resistance of building components see Bibliography.

NOTE 2 The VSB is designed and tested on the basis of its application, including:

a) vehicle type, mass and speed of the assessed vehicle-borne threat;

b) its geographical application (e.g. climate conditions);

c) intended site conditions (e.g. rigid or non-rigid soil).

It does not cover 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 covered in IWA 14-2.
