Overview

EN 50436-2:2014/A1:2015 is a European standard developed by the European Committee for Electrotechnical Standardization (CENELEC) under the CLC/BTTF 116-2 working group. This updated standard specifies test methods and performance requirements for alcohol interlock instruments equipped with a mouthpiece that measure breath alcohol concentration for general preventive use. It aims to drive consistency, reliability, and accuracy in devices designed to prevent impaired driving by detecting alcohol levels from breath samples.

This amendment (A1) published in 2015 refines the general test methods detailed in the original 2014 edition, ensuring that alcohol interlock systems and authorized accessory devices-such as cameras or GPS modules linked to event data-meet stringent operational criteria. EN 50436-2:2014/A1:2015 is adopted by CENELEC member states and applies primarily to devices intended for installation and use in vehicles for road safety enhancement.

Key Topics

• Alcohol Interlocks with Mouthpieces: Defines instruments that use disposable or fixed mouthpieces to capture breath samples for alcohol measurement.
• Test Methods: Standardized procedures for verifying device accuracy, reliability, calibration stability, environmental resilience, and data handling.
• Performance Requirements: Minimum criteria for measurement accuracy, response time, sensitivity, and operational safety under typical vehicle conditions.
• Accessory Devices: Guidance on testing integrated devices authorized by the manufacturer, such as GPS and cameras related to alcohol interlock event data.
• Preventive Applications: Focuses on general-use scenarios for alcohol interlocks intended to reduce alcohol-impaired driving incidents.
• Amendment A1 Updates: Modifies clause 5 on general test methods, including requirements for accessory device testing within the alcohol interlock system.

Applications

EN 50436-2:2014/A1:2015 alcohol interlock instruments serve an essential role in automotive safety and public health by enabling:

• Preventive Driver Screening: Devices can be installed in private and commercial vehicles to prevent unsafe operation by intoxicated drivers.
• Fleet Safety Management: Companies managing vehicle fleets utilize these instruments to enforce alcohol-free policies and maintain regulatory compliance.
• Law Enforcement and Public Transport: Authorities use standardized breath alcohol measuring instruments to reduce accident risks in public transportation and controlled driving environments.
• Research and Development: Manufacturers and testing laboratories use this standard to develop, verify, and certify breath alcohol measurement technologies.

The standard supports harmonized product testing which enhances trust in alcohol interlocks across the European Union and facilitates market access for compliant devices.

Related Standards

• EN 50436-1: General requirements for alcohol interlock systems including installation and calibration.
• EN 50436-3: Detailed specifications for alcohol interlocks integrated into ignition systems.
• ISO/IEC 17025: Competence requirements for testing and calibration laboratories assessing breath alcohol instruments.
• European Road Safety Regulations: National and EU directives referencing breath alcohol detection equipment for vehicle safety.

By adhering to EN 50436-2:2014/A1:2015, manufacturers, regulators, and operators contribute to safer road environments through reliable breath alcohol measuring instruments designed for general preventive use. This standard remains critical in advancing technology that mitigates drunk driving risks accurately and consistently.
