EN 50436-1:2014

This European Standard specifies test methods and performance requirements for breath alcohol con¬trolled alcohol interlocks. It covers alcohol interlocks intended to be used in programmes for drink driving offenders as well as in programmes monitored or controlled in a comparable way. This European Standard is directed at test laboratories and manufacturers of alcohol interlocks. It defines requirements and test procedures for type approval. Several parameters (such as alcohol concentration or breath volume) are specified in this European Standard for the purpose of type testing according to this European Standard only. However, it may be neces¬sary 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. This European Standard does not apply to –alcohol interlocks intended for general preventive use (see EN 50436-2), –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.
