Alcohol interlocks - Test methods and performance requirements -- Part 2: Instruments having a mouthpiece and measuring breath alcohol for general preventive use
This European Standard specifies test methods and performance requirements for breath alcohol controlled alcohol interlocks having a mouthpiece. It covers alcohol interlocks intended for general preventive use. This European Standard is mainly directed to test laboratories and manufacturers for alcohol interlocks. It defines requirements and test procedures for type approval. Several parameters (as for example alcohol concentration or breath volume) are specified in this European Standard for the purpose of type testing according to this standard only. However, it may be necessary according to national regulations or depending on user requests to set the values of the prescribed parameters differently for use of the alcohol interlocks.
Alkohol-Interlocks - Prüfverfahren und Anforderungen an das Betriebsverhalten -- Teil 2: Geräte mit Mundstück zur Messung des Atemalkohols für den allgemein-präventiven Einsatz
Diese Europäische Norm legt Prüfverfahren und Anforderungen an das Betriebsverhalten für atemalkoholgesteuerte Alkohol-Interlocks fest, die ein Mundstück besitzen. Sie behandelt Alkohol-Interlocks, die für den allgemeinpräventiven Einsatz vorgesehen sind. Diese Europäische Norm richtet sich hauptsächlich an Prüflaboratorien und Hersteller von Alkohol-Interlocks. Sie legt Anforderungen und Prüfverfahren für die Typzulassung fest. Einzelne Parameter (wie zum Beispiel Alkoholkonzentration oder Atemvolumen) sind in dieser Europäischen Norm nur für den Zweck der Baumusterprüfung nach dieser 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 Systeme des Fahrzeugs integriert sind. Diese Europäische Norm gilt nicht für – Alkohol-Interlocks, die hauptsächlich für den Einsatz in Verkehrssicherheits-Programmen für Trunkenheitsfahrer vorgesehen sind (siehe EN 50436-1), – Geräte, die die Alkoholkonzentration in der Innenraumluft des Fahrzeugs messen, – Alkohol-Interlocks, die kein Mundstück besitzen.

Introduction
The main purpose of alcohol interlocks is to prevent persons with blood alcohol concentrations exceeding
a set limit value from driving a vehicle. The general preventive use, being the object of this standard, is
complementary to the use according to the standard EN 50436-1 directed towards programs for drink-
driving offenders to enhance traffic safety. The general preventive use concerns a much larger number of
drivers and vehicles. The primary target is to hinder a casually intoxicated person with temporarily
impaired judgement from driving a vehicle. It applies both to professional and private drivers, and it
applies to all vehicles in which careless driving could be hazardous.
Alcohol interlocks should not represent a significant impediment to the normal use of a vehicle.
The purpose of this European Standard is to specify essential performance requirements and to provide
the respective test methods for presently available technologies. The technology of alcohol interlocks is
rapidly evolving, and further innovations can be expected. These could be considered in future
amendments or new parts of this European Standard.
Furthermore, it should be recognised that the purpose of alcohol interlocks may to some degree violate
the privacy. There is thus good reason to apply a principle of caution when defining requirements and test
methods for alcohol interlocks.

1 Scope
This European Standard specifies test methods and performance requirements for breath alcohol
controlled alcohol interlocks having a mouthpiece. It covers alcohol interlocks intended for general
preventive use.
This European Standard is mainly directed to test laboratories and manufacturers for alcohol interlocks. It
defines requirements and test procedures for type approval.
Several parameters (as for example alcohol concentration or breath volume) are specified in this
European Standard for the purpose of type testing according to this standard only. However, it may be
necessary according to national regulations or depending on user requests to set the values of the
prescribed parameters differently for use of the alcohol interlocks.
This European Standard also applies to alcohol interlocks integrated into other systems of the vehicle.
This European Standard does not apply to
– alcohol interlocks intended to be used mainly in traffic safety programs for drink driving
offenders (see EN 50436-1),
– instruments measuring the alcohol concentration in the ambient air in the vehicle,
– alcohol interlocks not having a mouthpiece.

4 General requirements
4.1 Blocking and unblocking
Unblocking shall be achieved after delivery of an accepted breath sample and its analysis with a breath
alcohol concentration below a limit value.
The alcohol interlock shall be blocking without supplementary action from the driver after switching off the
ignition of the vehicle motor and the following expiration of a restart period.
The restart period has to be at least 1 min.
4.2 Override function
An override function is permissible.
It shall be possible to enable or to disable the override function.
In case the alcohol interlock has an override function, the override function shall be activated. The use of
the override function by the user shall be indicated.
4.3 Influence on the vehicle motor
The alcohol interlock shall not influence a running vehicle motor, even in the case of a missed or a failed
retest.
4.4 Vehicle circuitry (applicable to alcohol interlocks for aftermarket installation only)
The electrical properties of the on-board circuitry of the vehicle (lead cross-sections, contact safety, etc.)
shall not be adversely affected by the alcohol interlock installed according to the manufacturer’s
instructions.
4.5 Concentration limit
The nominal breath-alcohol-concentration limit of the alcohol interlock shall be at least 0,09 mg/l.
4.6 Mouthpiece
The alcohol interlock shall have an exchangeable mouthpiece.
4.7 Data memory
A data memory in the alcohol interlock is optional.
Examples for events to be recorded are
– test results with a concentration value above the limit value,
– missing delivery of a breath sample during a retest,
– manipulation or circumvention attempts,
– overriding and bypassing,
– detachment and reattachment of handset,
– connections and disconnections of supply voltage.
If the alcohol interlock records one or several of these events, the correct recording with date and time
shall be tested.
Data shall be stored in such a way, that it will not be lost due to unintended data corruption or low vehicle
battery voltage.
NOTE There may be national regulations on data storage and evaluation.

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 an unblocked state.
4.15 Wireless communication
