Alcohol interlocks - Test methods and performance requirements - Part 1: Instruments for drink-driving-offender programs
This European Standard specifies test methods and performance requirements for breath alcohol con¬trolled alcohol interlocks. It covers alcohol interlocks intended to be used in programmes for drink driving offenders as well as in programmes monitored or controlled in a comparable way. This European Standard is directed at test laboratories and manufacturers of alcohol interlocks. It defines requirements and test procedures for type approval. Several parameters (such as alcohol concentration or breath volume) are specified in this European Standard for the purpose of type testing according to this European Standard only. However, it may be neces¬sary due 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 Standard also applies to alcohol interlocks integrated into other control systems of the vehicle. This European Standard does not apply to – alcohol interlocks intended for general preventive use (see EN 50436-2), – instruments measuring the alcohol concentration in the ambient air in the vehicle, – alcohol interlocks not having a mouthpiece, – methods of installation and connections to the vehicle.
Alkohol-Interlocks - Prüfverfahren und Anforderungen an das Betriebsverhalten - Teil 1: Geräte für Programme mit Trunkenheitsfahrern
Diese Europäische Norm legt Prüfverfahren und Anforderungen an das Betriebsverhalten für atemalkohol¬gesteuerte Alkohol-Interlocks fest. Sie behandelt Alkohol-Interlocks, die für den Einsatz in Programmen für Trunkenheitsfahrer als auch in Programmen, die in ähnlicher Weise überwacht oder beaufsichtigt werden, vorgesehen sind. Diese Europäische Norm richtet sich an Prüflaboratorien und Hersteller von Alkohol-Interlocks. Sie legt Anforderungen und Prüfverfahren für die Typprüfung fest. Einzelne Parameter (wie zum Beispiel Alkoholkonzentration oder Atemvolumen) sind in dieser Europäischen Norm nur für den Zweck der Typprüfung nach dieser Europäischen Norm festgelegt. Möglicherweise ist es jedoch notwendig, auf Grund von nationalen Vorschriften oder abhängig von Benutzerwünschen die Werte dieser Parameter für den Einsatz der Alkohol-Interlocks abweichend festzulegen. Diese Europäische Norm gilt auch für Alkohol-Interlocks, die in andere Steuersysteme des Fahrzeugs integriert sind, als auch für mit dem Alkohol-Interlock verbundene Zusatzgeräte. Diese Europäische Norm gilt nicht für – Alkohol-Interlocks, die für den allgemein-präventiven Einsatz vorgesehen sind (siehe EN 50436-2), – Geräte, die die Alkoholkonzentration in der Innenraumluft des Fahrzeugs messen, – Alkohol-Interlocks, die kein Mundstück besitzen, – Installationsverfahren und Verbindungen zum Fahrzeug.

Introduction
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. EN 50436 series specifies test
methods and essential performance requirements for alcohol interlocks and gives guidance for
decision makers, purchasers and users.
The content and requirements of this part of EN 50436 are based on the experience and necessities of
drink driving offender programmes in different countries over several decades. Therefore, alcohol
interlocks used in programmes for drink driving offenders should comply with this European Standard.
Alcohol interlocks for general preventive use are the subject of EN 50436-2. General preventive use,
which concerns a much larger number of drivers and vehicles, applies to both professional and private
drivers of motor vehicles.
The purpose of EN 50436 series is to specify essential performance requirements and to provide the
respective test methods for available technologies. The technology of alcohol interlocks continues to
evolve, and further innovations can be expected. These could be considered in new parts or revisions
of this European Standard.

4.5 Mouthpiece
The alcohol interlock shall have an exchangeable mouthpiece.
4.6 Readiness
The alcohol interlock shall provide a visual and/or audible indication when it is ready for a breath test.
A breath test shall only be accepted after a ready indication.
4.7 Data memory, download and evaluation
The alcohol interlock shall be capable of recording events with date and time in a data memory, even if
the handset is disconnected. These events are at least the following:
– breath samples,
– test results,
– 11 – EN 50436-1:2014 (E)
– blocking and not-blocking,
– information about the use of the vehicle, such as motor start and stop, vehicle motion or
distance driven,
– missed retest,
– overriding and bypassing,
– handset exchange,
– connections and disconnections of supply voltage,
– changing of parameters and adjustments,
– results of calibration, verification and/or readjustment.

interlocks that are combined with other vehicle systems or integrated into them.
Data shall be stored in such a way that it will not be lost or corrupted.
It shall be possible to download and evaluate the data. Downloading and reading of the data shall only
be possible by authorised access.
NOTE 2 There may be national regulations on data storage, transmission, access and evaluation.
NOTE 3 It is foreseen that an additional part of this series of European Standards for alcohol interlocks will be
developed concerning data encryption and data protection.
4.8 Retests
The alcohol interlock shall be capable of requesting retests by visual and/or audible signals at
adjustable random time intervals.
NOTE National regulations may restrict the use of visual or audible signals.
When requesting a retest, the alcohol interlock shall remain in the not-blocking state as long as the
motor is running or the restart period is not expired.
4.9 Recall
The alcohol interlock shall be capable of requesting an earlier service if certain events occur (for
example failed initial test, failed or missed retest, overriding, bypassing).
4.10 Override function
An override function is permissible.
It shall be possible to enable or to disable the parameter permitting the override function.
It shall be indicated when the alcohol interlock is in the override mode. It shall be possible to end the

Tests of different parts of the alcohol interlock may be performed separately, as to be agreed between
the manufacturer and the testing laboratory.
4.12 Communication integrity
If the handset of the alcohol interlock is detachable or if the handset and the control unit communicate
through wireless communication, the communication between the handset and the control unit shall be
encoded in a secure method so that it is difficult to compromise the communication integrity and to
bring the alcohol interlock into a not-blocking state.
NOTE It is foreseen that an additional part of this series of European Standards for alcohol interlocks will be
developed concerning data encryption and data protection.
4.13 Wireless communication
If the handset and the control unit of the alcohol interlock transmit signals between each other by
wireless communication, the alcohol interlock shall go into a not-blocking state not later than 30 s after
delivery and analysis of an accepted breath sample with a breath alcohol concentration below the limit
value.
The maximum distance for the wireless communication between the handset and the control unit
under free field conditions shall be 50 m.
4.14 Basic functionality
Basic functionality of the user guidance includes all means necessary to lead the user through the
measuring procedure and to perform an accepted measurement. This includes all indications to signal
each step of the procedure and the correct interpretation of the result. At least the following shall be
indicated:
– warm-up time;
– test requested;
– test accepted;
– test not accepted;
– test passed;
– test failed;
– test to be repeated;
– restart period.
The indication may be audible and/or visible and/or a text display.
5 General test methods
5.1 Samples
All the tests shall be carried out on two alcohol interlocks. However, at the discretion of the test
laboratory additional samples may be used if this is not considered to affect the results of the other
tests.
Integrated batteries may be replaced or recharged before individual tests unless otherwise stated.
Accessory devices of the alcohol interlock authorised by the manufacturer as being part of the alcohol
interlock system and which are intended to be used in the vehicle during operation shall be tested
according to this European Standard. For example cameras or GPS systems generating data related
to event data of the alcohol interlock, as well as accessory devices handling or transferring data for a
– 13 – EN 50436-1:2014 (E)
drink-driving-offender programme are to be tested. For example GPS or fleet management systems
only receiving data from the alcohol interlock are not to be tested.
NOTE National regulations may define which accessory devices have to be type tested.
All the tests shall be carried out on two samples of each accessory device. However, at the discretion
of the test laboratory additional samples may be used if this is not considered to affect the results of
the other tests.
5.2 Preparation of alcohol interlock before testing
The alcohol interlock shall be calibrated and adjustments shall be carried out, if needed, at the
beginning of the test procedure and before the long-term stability test (see Clause 14) by the
manufacturer or according to his instructions to obtain correct indications.
If the calibration interval given by the manufacturer expires during the test procedure, the alcohol
interlock may be readjusted after the expiry, if necessary, with the exception of the durability tests (see
Clause 8) and the long-term stability test (see Clause 14).
With the exception of the tests for manipulation and circumvention (see Clause 12), the measures
against manipulation and circumvention may be de-activated for the tests.
5.3 Sequence of tests
5.3.1 Alcohol interlock
The alcohol interlocks shall be tested according to the respective test procedures in the following
sequence: electrical tests (Clause 6), calibration curve (Clause 7), durability tests (Clause 8).
The sequence of the remaining tests may be agreed between the test laboratory and the manufacturer.
The tests according to Clauses 10 to 13 may be performed with two additional alcohol interlocks in
parallel.
The long-term stability test of Clause 14 may be performed with two additional alcohol interlocks in
parallel.
5.3.2 Accessory devices
The following tests shall be performed with the accessory devices:
– tampering (4.3), to be tested together with the alcohol interlock,
– data memory, download and evaluation (4.7), where applicable,
– electrical tests (Clause 6) to be tested together with the alcohol interlock,
– durability (Clause 8), with drop test (8.4) applicable only for accessory devices intended to be
removable by the user,
– environmental tests (Clause 9) without pressure test (9.6), to be tested together with the alcohol
interlock.
After having passed the tests according to 5.3.2 the accessory devices shall perform as specified by
the manufacturer.
5.4 Normal conditions for tests
All tests shall be performed with the alcohol interlock connected to the power supply voltage and
power-on under the following normal conditions, unless otherwise stated:
– voltage: as specified by the manufacturer (nominal operating voltage ± 5 %) or with sufficiently
charged integrated batteries;
– ambient temperature: T = 23 °C ± 5 °C;
– ambient pressure: 98 kPa ± 20 kPa;
– test gases:
dry gases, temperature 23 °C ± 5 °C, or
wet gases, temperature 34 °C ± 2 °C with temperature of the water bath known + 0,1 °C;
– test gas flow: 0,25 l/s ± 0,05 l/s;
– uncertainty of test gas concentration: ± 0,01 mg/l;
– test gas volume: 1,5 l ± 10 %.
5.5 Functional test
As stated in the respective clauses, tests shall be performed according to one of the following three
test types.
The limit value at or above which the alcohol interlock is blocking shall be adjusted to 0,25 mg/l for
these tests.
NOTE The limit value of 0,25 mg/l is chosen to facilitate the test procedures and to differentiate between the
influence of disturbances and the uncertainty of the measurement results. Because the test of the calibration
curve is additionally performed at different concentrations and the related requirements have to be fulfilled, the
test results of a type testing according to this European Standard are also applicable to alcohol interlocks having
a different limit value in the range of 0,09 mg/l up to 0,4 mg/l.
Test type 1
Test gas with an alcohol concentration of 0,30 mg/l shall be applied to the alcohol interlock
successively ten times in intervals of at least 3 min. The alcohol interlock shall remain in a

with functional status A as defined in ISO 16750-1.
6.3 Excess supply voltage
a) An alcohol interlock with 12 V nominal operating voltage shall be subjected at 65 °C ambient
temperature to an excess supply voltage of 18 V for 60 min according to ISO 16750-2:2010,
4.3.1.1.
An alcohol interlock with 12 V nominal operating voltage shall be subjected at room temperature to
an excess supply voltage of 24 V for (60 + 6) s according to ISO 16750-2:2010, 4.3.1.2.
The alcohol interlock shall after the test fulfil functional status C as defined in ISO 16750-1 when
tested according to 6.10.
b) An alcohol interlock with 24 V nominal operating voltage shall be subjected at 65 °C ambient
temperature to an excess supply voltage of 36 V for 60 min according to ISO 16750-2:2010, 4.3.2.
The alcohol interlock shall after the test fulfil functional status C as defined in ISO 16750-1 when
tested according to 6.10.
6.4 Short-circuit
a) The alcohol interlock shall be tested for the short circuit protection of signal circuits according to
ISO 16750-2:2010, 4.10.2 with the following test conditions:
– alcohol interlocks with 12 V nominal operating voltage: U = 16 V,
Smax
– alcohol interlocks with 24 V nominal operating voltage: U = 32 V.
Smax
The alcohol interlock shall after the test fulfil functional status C as defined in ISO 16750-1 when
tested according to 6.10.
Communication lines such as RS-232, USB or Ethernet are not be considered to be signal circuits
and are not to be included in this test.
b) The alcohol interlock shall be tested for the short circuit protection of load circuits according to
ISO 16750-2:2010, 4.10.3.
The alcohol interlock shall after the test fulfil the relevant functional status as required in
ISO 16750-2:2010, 4.10.3 when tested according to 6.10.
6.5 Reversed polarity
An alcohol interlock with power supply from the vehicle battery shall be tested according to
ISO 16750-2:2010, 4.7.2.3.
If the alcohol interlock has integrated exchangeable batteries, the batteries shall be inserted with
reversed polarity for a duration of 60 s.
After the test and after replacing all blown fuse links, the alcohol interlock shall fulfil functional status C
as defined in ISO 16750-1 when tested according to 6.10.
6.6 Low-power-consumption state
The current in low-power-consumption state (sleep mode of the instrument) shall not exceed 5 mA at
12 V and at 24 V for the alcohol interlock. For short periods of time the current may be higher.
NOTE The limit of 5 mA is high in respect of extending the battery life of a standing vehicle. However, this limit
is necessitated by requirements of detecting bypassing, short warm-up time, internal clock, monitoring power
disconnection or exchange of handset, among others, together with the state of the technology. Additionally, for
the standard capacity of present-day vehicle batteries it is a reasonable compromise.
