EN 50148:1995

Electronic taximeters

This Standard applies to electronic taximeters, hereinafter referred to by the general term taximeters, to be installed on public hire vehicles (taxis or cabs) which, with the aid of electronic devices, calculate and indicate the amount to be paid by the passenger of the taxi. This standard does not apply to taximeters being remotely controlled by external intelligence as far as it concerns the functions described in this standard. This standard does not deal with performance requirements of the taximeter after installation or with the installation itself.

Overview

EN 50148:1995 - Electronic taximeters (published by CLC) is a European standard that defines requirements for electronic taximeters intended for installation in public hire vehicles (taxis/cabs). The standard covers devices that, using electronic systems, calculate and indicate the fare payable by the passenger. It explicitly excludes taximeters that are remotely controlled by external intelligence for the functions described, and it does not address installation procedures or device performance after installation.

Key Topics

Based on the standard’s scope and classification (ICS 03.220.01; 43.040.30), EN 50148 focuses on device-level requirements and factory-level behavior. Key technical topics include:

• Functional scope: definitions of the taximeter’s role in calculating and indicating fares for public hire vehicles.
• Control and indicating devices: expectations for displays, input controls and operator interfaces used by drivers and passengers.
• Device-level integrity: requirements related to how the electronic taximeter performs its core functions independently of vehicle installation.
• Exclusions and interfaces: clarification that remotely controlled devices and installation/performance-in-service are outside this standard’s remit.
• Documentation and marking: requirements for supply documents, identification and basic product information provided by manufacturers.

Note: EN 50148 deals with taximeter device specifications rather than post-installation performance, calibration procedures or vehicle wiring.

Applications

EN 50148 is practical for organizations and professionals involved with taxi equipment and fare systems:

• Manufacturers and designers of electronic taximeters - to ensure devices meet standardized device-level requirements.
• Type-approval and conformity assessment bodies - for evaluating taximeter hardware compliance at the factory level.
• Test laboratories - for device testing against functional and documentation requirements.
• Procurement teams and fleet managers - when specifying compliant taximeter models for purchase.
• Regulators and local authorities - as a reference for device standards (while local fare regulation and installation rules remain separate).

Practical use cases include product development, pre-installation conformity checks, technical procurement specifications, and documentation of device capabilities.

Related Standards

Relevant complementary standards and topics to consider:

• National and regional metrology/fare regulation standards (local accuracy and calibration requirements).
• Standards governing vehicle electrical installations and mounting of equipment (installation and in-service performance).
• Other standards for indicating and control devices and transport equipment (see ICS classifications 03.220.01 and 43.040.30).
