NBN EN 50436-1:2006

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.
