EN 15964:2011 (E) 5 Introduction 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) European standardization does not cover those subjects that clearly belong to the domain of regulation of the Member States unless this is explicitly supported by the national authority (i.e. regulatory measures remain the competence of the various Member States). SIST EN 15964:2011



EN 15964:2011 (E) 6 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. 2 Normative references The following referenced documents are indispensable for the application of this document.

EN 15964:2011 (E) 9 6.2 Maximum permissible error (MPE) The maximum permissible error is +/-0,02 mg/L for alcohol concentrations up to and including 0,20 mg/L. The maximum permissible error is ± 10 % of nominal concentration for alcohol concentration above 0,20 mg/L. 6.3 Measurement range Devices shall be capable of measuring alcohol concentrations in the range 0,00 mg/L to 2,00 mg/L. 6.4 Operating environmental conditions 6.4.1 Temperature The devices shall be capable of use between – 5 °C and 40 °C. If the manufacturer specifies that the device may be operated outside this range, then it shall fulfil the requirements of this standard for these conditions. If the device is operated outside the specified range, then it may indicate that it cannot take a sample. 6.4.2 Humidity The devices shall be capable of use up to 93 % RH. 6.5 Ease of use In normal mode, the device shall not be influenced in its operation by user error. 6.6 Breath sampling method The device shall monitor the continuity of exhalation and the volume given in order to identify an acceptable breath specimen for analysis. The device shall give a signal if the acceptable volume is not achieved and shall terminate the test procedure at that point, after which the device may reset automatically and indicate readiness to accept a further attempt. Manufacturers may at their discretion set a limit for the number of attempts to provide a breath specimen for analysis from any one subject. For a device, the pressure, volume and flowrate required to collect a satisfactory breath specimen shall comply with the following absolute values:  minimum volume = 1,2 L;  minimum flowrate = 0,15 L/s;  maximum pressure = 30 hPa at a flowrate of 0,2 L/s, mouthpiece attached. 6.7 Expression of results 6.7.1 Units of measurement In test mode the units of measurement shall be mg/L or equivalent unit. SIST EN 15964:2011



EN 15964:2011 (E) 10 6.7.2 Rounding In test mode, the device shall display the result of each test to the nearest 0,001 mg/L or equivalent unit. In normal mode, it shall report the result of each test rounded down to the nearest scale interval of 0,01 mg/L or equivalent when in digital format and the appropriate band when in indicating format. 6.7.3 Display The units of measurement shall be displayed in the vicinity of the result. The result of measurement of the alcohol content of the breath specimen may be presented in two ways:  indicating format where the alcohol content of the sample is presented by a system of lights or characters on an alpha-numeric display;  digital format where the alcohol concentration is expressed in a quantitative format. It shall be permissible for a device to indicate zero for values up to and including 0,03 mg/L; It shall be permissible for a device to operate in indicating and digital format simultaneously. It shall not be possible for the display to be converted from indicating format to digital format in normal mode. The display shall permit easy reading of the results in all levels of ambient light. The results and other indications shall be able to be observed for at least one minute or alternatively it shall be possible to recall the result of the last test. However, a new measurement shall be able to be initiated at any time during the display of the result. 6.8 Adjustment The procedure and equipment for adjusting the breath alcohol test device to a reference alcohol mass concentration shall be supplied by the manufacturer. For this purpose, the gas may be dry or wet, provided it can be shown on the device that the results from each are equivalent.
The required period between two successive adjustments shall be at least three months. During this period the results shall remain stable (see 7.4.4). 6.9 Start-up time Within the specified operating temperature range, the device shall be ready to carry out a measurement in less than 3 minutes after switching on. 6.10 Frequency of measurement The maximum allowed time between two measurements shall be:  ≤ 1 min for a concentration ≤ 0,05 mg/L;  ≤ 2 min for a
concentration > 0,05 mg/L and ≤ 0,40 mg/L;  ≤ 3 min for a concentration > 0,40 mg/L and ≤ 2,0 mg/L. SIST EN 15964:2011



EN 15964:2011 (E) 11 6.11 Power supply duration Devices shall have an internal power supply. With batteries fully charged, the breath alcohol test device shall be able to perform at least 75 individual measurements, each from switch on to result displayed within the operating temperature range. 6.12 Data storage When a permanent data memory is provided the downloaded data shall include at least:  serial number of the device;  date and time of the test;  type of test (e.g. normal mode);  measurement result or an indication that the test was not completed;  unit of measurement if applicable. The device shall give a warning if the memory is approaching the limit of its capacity (see also requirements in Clause 9). 6.13 General device functions In addition to the breath alcohol testing requirements, checks shall be made on general device functions to ensure that the device performs in accordance with the manufacturer's information. 7 Metrological characteristics for testing 7.1 General conditions Immediately prior to testing and if appropriate, the device may undergo adjustment to a reference ethanol vapour test gas.
For example, in case of lot by lot testing, the manufacturer shall perform the adjustment.

The tests shall be able to check that the devices comply with the provisions of this document in the different submitted power supply configurations. The effect of each factor shall be determined in turn with all other factors being at their reference level. The effects shall not be combined unless otherwise specified. In performing the tests in this scheme a complete breath test using the standard vapours shall be carried out. Wherever possible, the test shall allow all aspects of the normal operation of the device to be verified. Tests shall be run at the reference point and the extreme points of each condition listed. The power supply used shall be of the type recommended by the manufacturer. The following tests shall be carried out on a device representative of devices intended for use and without any additional protective means. SIST EN 15964:2011



EN 15964:2011 (E) 12 7.2 Test gas characteristics The gas used shall be wet gas unless otherwise stated for a particular test. Wet gas shall be generated at a temperature of (34,0 ± 0,5) °C with a relative humidity of at least 90 %. The carrier gas shall have 5 % of CO2 (volumetric fractions). If the influence of 5 % of CO2 is no more than 0,01 mg/L for a concentration of 0,4 mg/L of ethanol then the carrier gas may be air. If changes of the O2 concentration in the carrier gas are relevant, the constitution of the carrier gas shall reflect the O2 concentration of human breath which may vary between 12 vol % and 21 vol %. The uncertainty of test gas concentration shall be ≤ 1/3 of MPE. The concentration of ethanol in the wet gas is calculated on the basis of the formula detailed in Annex B. 7.3 Reference conditions The reference conditions defined for the tests are as follows:  Temperature: ambient temperature: (22 ± 4) °C;  humid
