DESCRIPTION

Breath alcohol test devices other than single use devices. Requirements and test methods

BS EN 15964:2011

Breath alcohol test devices are widely used in Europe in professional applications like law enforcement,
promotion of traffic safety and work safety. Test results may lead to severe consequences for everybody
involved. Therefore, the test results need to be reliable and acceptable.
This document contains a description of the minimum technical requirements to be met for compliance testing
of multi-use breath alcohol test devices. It contains also details concerning the compliance testing and
performance requirements of breath alcohol test devices as a prerequisite for approval 1).
References may also be made to sections of this document for lot-by-lot testing.
Any appropriate technology capable of providing the functionality required in this document may be used.
Breath alcohol test devices considered in this standard use mouthpieces for sampling the breath specimens.

1 Scope
This European Standard applies to breath alcohol test devices which measure the concentration of alcohol
contained in an exhaled breath sample intended to be used for screening or preliminary testing. This standard
specifies requirements for basic safety and performance, test methods and requirements for marking, labelling
and operating instructions.
This standard gives guidelines for type approval procedure consisting of a number of technical performance
tests, but excluding in vivo tests, that are carried out on devices supplied by the manufacturers.
In vivo tests, which are designed to test the ability of the device to work with real subjects, may be arranged in
compliance with national requirements.
This standard is not applicable to devices covered by OIML R 126:1998 (Evidential breath analyzers) or single
use testers.
Devices are designed for law enforcement
