Alcohol interlocks - Test methods and performance requirements - Part 1: Instruments for drink-driving-offender programs

EN 50436-1 specifies test methods and performance requirements for breath alcohol controlled 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 testing. Several parameters (such as 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 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 as well as to accessory devices connected to the alcohol interlock.

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.

Alkoholne zapore - Preskusne metode in zahtevane lastnosti - 1. del: Instrumenti za uporabo v programih proti pijanim voznikom

Standard EN 50436-1 določa preskusne metode in zahtevane lastnosti za alkoholne zapore, ki merijo alkohol v sapi. Obsega alkoholne zapore, ki se uporabljajo v programih za vinjene voznike in v programih, pri katerih spremljanje ali nadzor poteka na primerljiv način. Ta evropski standard je usmerjen v preskuševalne laboratorije in proizvajalce alkoholnih zapor. Določa zahteve in preskusne postopke za tipsko preskušanje. Več parametrov (kot je koncentracija alkohola ali prostornina vdiha) je navedenih v tem evropskem standardu za namen tipskega preskušanja samo v skladu s tem standardom. Vendar je mogoče treba zaradi nacionalnih predpisov ali glede na zahteve uporabnikov drugače nastaviti vrednosti predpisanih parametrov, kadar veljajo alkoholne zapore. Ta evropski standard se uporablja tudi za alkoholne zapore, vgrajene v druge nadzorne sisteme vozila, ter za pomožne naprave, povezane z alkoholno zaporo.

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.

1 Scope

This European Standard specifies test methods and performance requirements for breath alcohol

controlled 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 testing.

Several parameters (such as 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

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 as well as to accessory devices connected to the alcohol interlock.
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.
