BRITISH STANDARD Vehicle security — Part a: Specification for locking systems for passenger cars and car derived vehicles BS AU 209-1 a:1 992 BS AU 209-1 a:1 992 Committees responsible for this British Standard The preparation of this British Standard was entrusted by the Automobile Standards Policy Committee (AUE/- ) to Technical Committee AUE/1 7, upon which the following bodies were represented: Association of Car Fleet Operators Automobile Association British Security Industry Association Consumers’ Association Consumer Policy Committee of BSI Department of Trade and Industry Department of Transport Freight Transport Association Home Office Institute for Consumer Ergonomics Ltd Master Locksmiths’ Association Metropolitan Police Motor Industry Research Association Road Haulage Association Ltd Royal Automobile Club Society of Motor Manufacturers and Traders Ltd This British Standard, having been prepared under the direction of the Automobile Standards Policy Committee, was published under the authority of the Standards Board and comes into effect on September 992 © BSI 07- 999 Amendments issued since publication First published October 986 Amd No Second

at the request of the Department of Transport and with the support of the Home Office and organizations connected with law enforcement, the motor vehicle construction industry and vehicle user organizations This edition supersedes BS AU 209- : 986, which is withdrawn Hitherto, no standard has existed for the United Kingdom that defines the performance and use of equipment intended to prevent or deter unauthorized entry into or removal of a motor vehicle This standard is not a substitute for anti- burst latch test requirements of vehicle doors, nor for protective devices used on the steering system, transmission or gear lever It is recognized that this standard covers a relatively new area, not previously standardized, and that it may be necessary to amend the requirements after initial experience of its use Other items may arise in due course Other Parts of BS AU 209 are: — Part 2: Specification for security against theft of in-car equipment for entertainment and communication purposes; — Part 3: Specification for security marking of glazing for passenger cars and car derived vehicles; — Part 5a: Specification for central power locking systems for passenger cars and car derived vehicles; — Part 6: Specification for dead locking systems for passenger cars and car derived vehicles The principles in this Part of BS AU 209 may be used with other vehicles However, this Part of BS AU 209 does not cover all requirements for medium and heavy commercial vehicles, which will be dealt with in a separate Part of the standard A British Standard does not purport to include all the necessary provisions of a contract Users of British Standards are responsible for their correct application Compliance with a British Standard does not of itself confer immunity from legal obligations Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages to 4, an inside back cover and a back cover This standard has been updated (see copyright date) and may have had amendments incorporated This will be indicated in the amendment table on the inside front cover ii © BSI 07- 999 BS AU 209-1 a:1 992 Scope This Part of BS

the tests in the internal closure trim may be removed, either completely or partially, provided that by doing so the strength of the linkages is not weakened and that the probe or simple tool is not permitted to pass into/through areas that would otherwise be restricted by the internal trim if it were present NOTE Exterior push buttons or handles shall either freewheel when in the locked state or be so constructed that, when in the locked state and sufficient force is applied so as to produce the full operating movement of the release button or handle, such movement shall not effect entry into the vehicle Removal of the internal trim is to negate the need for the tester to be familiar with the latch operating mechanism when forming the probe or simple tool Installation Passenge r or luggage

of any of the closures and thereby gain access to the passenger or luggage compartment by the methods described in , compartment so that the vehicle is capable of being secured against unauthorized entry NOTE Attention should be given to the installation of retention components (hinges and slide mechanisms) of doors and lids giving access to the interior of the vehicle to ensure that they are without permanently distorting the closure or mounted such that they cannot, without damage, be dismantled surrounding body aperture or removed to gain access to the vehicle from the exterior If contact can be made with any part of the latch assembly, latch linkage, locking device, or internal locking and unlocking control from outside the vehicle using a probe formed from wire of diameter
