DIN EN 50436-2:2014-09

The 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. 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 specifies 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 du 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 Stand also applies to alcohol interlocks integrated into other control systems of the vehicle as well as to accessory devices connected to the alcohol interlock. The responsible committee is Subcommittee DKE/UK 966.2 "Atemalkohol-Messung" ("Alcohol interlocks") of the DKE (German Commission for Electrical, Electronic and Informational Technologies) at DIN and VDE.
