Overview

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. The EN 50436 series specifies test methods and essential performance requirements for alcohol interlocks and gives guidance for authorities, decision makers, purchasers and users. Alcohol interlocks are often intended for aftermarket installation. For this purpose, they are connected to the electric and control circuits of the vehicle. This installation of an alcohol interlock should not interfere with the proper performance of the vehicle, should not impair the safety and security of the vehicle and should be as straightforward as possible. Additionally, the installation costs should be low in relation to the total cost of the alcohol interlock. This European Standard defines the content and the layout of an installation document providing necessary and useful information about the aftermarket installation of an alcohol interlock into a vehicle. It details the type of the vehicle, connection schematics, accessibility instructions and recommendations to avoid safety risks. This document is mostly intended for vehicle manufacturers and manufacturers of alcohol interlocks. The contents and layout ensures that the information document is easy to use for installers in different countries and can be available in paper or electronic format. This European Standard is applicable both to alcohol interlocks for drunk driving programs (as in EN 50436-1) and to alcohol interlocks for general preventive use (as in EN 50436-2). 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.
