Road traffic noise reduction devices. Non-acoustic performances. Part 2: Methods for determining general safety and environmental characteristics

This technical specification outlines a specific methodology for evaluating the non-acoustic performance characteristics of devices designed to reduce road traffic noise. Focusing exclusively on the second part of the series, it establishes comprehensive procedures for assessing general safety requirements and environmental properties. The document provides a structured framework for testing, ensuring that such noise control installations meet baseline safety standards and function effectively within their intended outdoor settings without causing secondary environmental impacts. It details the necessary conditions for sample preparation, test setups, and measurement protocols to guarantee consistency and reliability across different evaluation scenarios. By defining these technical criteria, the standard facilitates the harmonization of assessment practices, allowing for the systematic verification of device durability, installation integrity, and material behavior under varying environmental stressors. The approach prioritizes objective data collection to support regulatory compliance and quality assurance processes within the domain of traffic noise mitigation infrastructure.
