Introduction to ECE R39
ECE R39 establishes requirements for vehicle speedometers and speed measurement equipment. The purpose of this regulation is to ensure that vehicle speed information is displayed accurately, reliably, and clearly to the driver. Compliance with these requirements plays an important role in improving road safety and supporting compliance with speed regulations.
Vehicle Speedometer Requirements
The ECE R39 standard defines technical requirements for the design, construction, installation, and performance of speedometers. Speedometers must provide accurate speed information and maintain reliable operation under various operating conditions. In addition, display readability and measurement accuracy must comply with the requirements specified in the regulation.
Testing and Evaluation Procedures
To verify compliance with ECE R39, a series of specialized tests and evaluations are conducted. These assessments include speed measurement accuracy verification, performance evaluation under different operating conditions, display accuracy checks, and compliance verification with regulatory requirements. The objective is to ensure accurate and dependable performance throughout the vehicle's service life.
The Role of ECE R39 in Vehicle Safety
Compliance with ECE R39 helps vehicle manufacturers and equipment suppliers develop products that meet international requirements. Accurate and reliable speedometers improve driver awareness of vehicle speed and help reduce risks associated with speeding or incorrect speed information.
