Introduction
The purpose of remote alcohol monitoring devices is to monitor the compliance of persons subject to
mandatory or voluntary programmes focused on monitoring alcohol consumption.
The purpose of EN 50980-1 is to specify essential performance requirements and to provide the
respective test methods for available technologies. The technology of remote alcohol monitoring
devices continues to evolve, and further innovations can be expected. These could be considered in
new parts or revisions of this European Standard.
1 Scope
This document specifies performance requirements and test methods for remote alcohol monitoring
devices that use breath alcohol testing technology. It covers remote alcohol monitoring devices having
a mouthpiece and which are intended to be used by participants in programmes designed to monitor
alcohol consumption.
This document is directed at test laboratories and manufacturers of remote alcohol monitoring devices.
It defines requirements and test procedures for type testing.
Several parameter settings (such as alcohol concentration, breath volume or units of measurement)
are specified in this document 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 parameter settings differently when the remote alcohol monitoring devices are in use.
