purpose of alcohol interlocks is to enhance traffic safety by preventing persons with alcohol concentrations exceeding a set limit value from driving a motor vehicle EN 50436 series specifies test methods and essential performance requirements for alcohol interlocks and gives guidance for decision makers, purchasers and users The content and requirements of EN 50436-1 are based on the experience and necessities of drink driving offender programmes in different countries over several decades Therefore, alcohol interlocks used in programmes for drink driving offenders should comply with the above European Standard Part is the principal document in EN 50436 series Alcohol interlocks for general preventive use are the subject of this part of EN 50436 General preventive use, which concerns a much larger number of drivers and vehicles, applies to both professional and private drivers of motor vehicles The purpose of EN 50436 series is to specify essential performance requirements and to provide the respective test methods for available technologies The technology of alcohol interlocks continues to evolve, and further innovations can be expected These could be considered in new parts or revisions of this European Standard BS EN 50436-2:2014+A1:2015 EN 50436-2:2014+A1:2015 (E) –6– Scope This European Standard specifies test methods and performance requirements for breath alcohol controlled alcohol interlocks having a mouthpiece It covers alcohol interlocks intended for general preventive use This European Standard is directed at test laboratories and manufacturers of alcohol interlocks It defines requirements and test procedures for type testing Several parameters (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 due to national regulations or depending on user requests to set the values of the prescribed parameters differently when the alcohol interlocks are in use This European Standard also applies to alcohol interlocks integrated into other control systems of the vehicle as well as to accessory devices connected to the alcohol interlock This European Standard does not apply to – alcohol interlocks intended for use in traffic safety programmes for drink driving offenders (see EN 50436-1), – instruments measuring the alcohol concentration in the ambient air in the vehicle, – alcohol interlocks not having a mouthpiece, – methods of installation and connections to the vehicle Normative references This clause of EN 50436-1 is applicable excepted as follows: st Add the following after the paragraph: EN 50436-1, Alcohol interlocks - Test methods and performance requirements -

Data memory, download and evaluation A data memory in the alcohol interlock is optional Examples of events which may be recorded are – breath samples, – test results, – blocking and not-blocking, – information about the use of the vehicle, such as motor start and stop, vehicle motion or distance driven, – missed retest, – overriding and bypassing, – handset exchange, – connections and disconnections of supply voltage, – changing of parameters and adjustments, – results of calibration, verification and/or readjustment NOTE For a full list of events see EN 50436-1:2014, Annex A If the alcohol interlock has a data memory, – events shall be recorded with date and time, even if the handset is disconnected, – data shall be stored in such a way that it will not be lost or corrupted, – it shall be possible to download and evaluate the data; downloading and reading of the data shall only be possible by authorised access, – it shall be possible to switch off the record of personal use data NOTE The data memory in the alcohol interlock includes both technical diagnostic and personal use data NOTE There may be national regulations on data storage, transmission and evaluation NOTE It is foreseen that an additional part of this series of European Standards for alcohol interlocks will be developed concerning data encryption and data protection 4.8 Retests The capability of the alcohol interlock to request retests by visual and/or audible signals at adjustable random time intervals is optional NOTE National regulations may restrict the use of visual or audible signals When requesting a retest, the alcohol interlock shall remain in the not-blocking state as long as the motor is running or the restart period has not expired BS EN 50436-2:2014+A1:2015 EN
