21、Nov 06 03:35:45 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 50436-1:2005 4 1 Scope This European Standard specifies test methods and performance requirements for breath alcohol controlled alcohol interlocks. It covers alcohol interlocks intended to be used mainly in traffic safety programs for dri
22、nk driving offenders. This European Standard is mainly directed to test laboratories and manufacturers for alcohol interlocks. Several parameters (as for example alcohol concentration or breath volume) are specified in this European Standard for the purpose of type testing according to this standard
23、 only. However, it may be necessary according to national regulations to set these parameters differently for use of the alcohol interlocks. 2 Normative references The following referenced documents are indispensable for the application of this document.

A breath test
31、result equal to or above this limit will prevent the vehicle motor from being started 3.7 retest breath test after the vehicle motor has been started 3.8 start period period after an accepted breath sample has been delivered during which the vehicle motor may be started 3.9 restart period period aft
32、er the ignition is switched off during which the vehicle motor may be started again without the presentation of another breath sample NOTE This restart period is intended to ensure the drivers ability to restart the vehicle motor after a stall situation. 3.10 bypass starting the vehicle motor withou

34、 physical) or any other secure method to provide a time-limited and use-limited ability to start the vehicle motor 3.12 tampering unauthorised change to or interference with the alcohol interlock or its installation in the vehicle or its functioning 4 General requirements 4.1 General An alcohol inte
35、rlock shall comply with the requirements of this European Standard. 4.2 Blocking and unblocking Unblocking shall be achieved after delivery and analysis of an accepted breath sample with a breath alcohol concentration below a limit value. An override function is permissible. The alcohol interlock sh
36、all be blocked without supplementary action from the driver after switching off the ignition of the vehicle motor and the following expiration of a restart period.

37、 period has to be at least 1 min. 4.3 Influence on the vehicle motor The alcohol interlock may only prevent starting the vehicle motor. It shall not influence a running vehicle motor, even in the case of a missed or a failed retest. 4.4 Vehicle circuitry The electrical properties of the on-board cir
38、cuitry of the vehicle (lead cross-sections, contact safety, etc.) shall not be adversely affected by the alcohol interlock installed according to the manufacturers instructions. 4.5 Mouthpiece The alcohol interlock shall have an exchangeable mouthpiece. 4.6 Data memory, download and evaluation The a
39、lcohol interlock shall be capable of recording events with date and time in a data memory, even if the handset is disconnected. These events are at least the following: breath samples and test results, blocking and unblocking, vehicle motor start or running and stop and/or vehicle motion, missing de
40、livery of a breath sample during a retest, detachment and reattachment of handset, connections and disconnections of supply voltage, manipulation or circumvention attempts, overriding and bypassing. Data shall be stored in such a way, that it will not be lost due to unintended data corruption or low
41、 vehicle battery voltage. It shall be possible to download the data and to evaluate the data. 4.7 Retests The alcohol interlock shall be capable of requesting retests by visual and/or audible signals at random time intervals. NOTE National regulations may restrict the use of visual signals. 4.8 Earl
42、y recall The alcohol interlock shall be capable of requesting an earlier service in case of certain events (for example failed initial test, failed or missed retest, overriding, bypassing). 4.9 Readiness The alcohol interlock shall provide a visual and/or audible indication when it is ready for a br
43、eath test. A breath test shall only be accepted after a ready indication. 4.10 Tampering The alcohol interlock shall be designed and built such that, when installed in a vehicle, according to the manufacturers instructions, it cannot be put out of service or be rendered ineffective or destroyed, wit
44、hout visible changes to the alcohol interlock or its installation. 4.11 Electromagnetic compatibility The alcohol interlock shall fulfil the relevant technical requirements of the European Directive 95/54/EC or the European Directive 2004/104/EC with regard to electromagnetic compatibility (EMC).
