Alcohol interlocks - Test methods and performance requirements -- Part 1: Instruments for drink-driving-offender programs

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 drink 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 only. However, it may be necessary according to national regulations to set these parameters differently for use of the alcohol interlocks.

3.4 blocked state state in which the vehicle motor cannot be started 3.5 unblocked state state in which the vehicle motor can be started 3.6 breath alcohol concentration limit limit value below which the vehicle motor may be started. A breath test 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 after 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 driver’s ability to restart the vehicle motor after a stall situation. 3.10 bypass starting the vehicle motor without providing an accepted breath test result below the concentration limit or without engaging the override function 3.11 override method of unblocking the start of the vehicle motor without providing an accepted breath test result below the concentration limit by use of a code or a key (electronic or 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 interlock 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 shall 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. SIST EN 50436-1:2006



EN 50436-1:2005 – 6 –
The restart 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 circuitry of the vehicle (lead cross-sections, contact safety, etc.) shall not be adversely affected by the alcohol interlock installed according to the manufacturer’s instructions. 4.5 Mouthpiece The alcohol interlock shall have an exchangeable mouthpiece. 4.6 Data memory, download and evaluation The alcohol 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 delivery 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 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 Early 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 breath 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 manufacturer‘s instructions, it cannot be put out of service or be rendered ineffective or destroyed, without 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).
