Overview
EN 1794-2:2024/prA1, published by the European Committee for Standardization (CEN), specifies methods and criteria for assessing the general safety and environmental performance of road traffic noise reducing devices under typical roadside conditions. This standard complements the acoustic requirements by focusing on non-acoustic aspects, including environmental impact and user safety, to ensure that roadside noise barriers and similar devices provide holistic performance in real-world applications.
This document, developed under CEN/TC 226 "Road equipment," is intended for use by manufacturers, designers, engineers, and regulatory authorities involved in the planning, installation, and maintenance of road noise reduction solutions throughout Europe.
Key Topics
The standard covers critical non-acoustic characteristics of noise reducing devices, ensuring that such devices are not only effective in noise abatement but also safe and environmentally sound for long-term roadside deployment. The main areas addressed include:
- General Safety Characteristics
- Structural integrity under typical roadside conditions
- Prevention of hazards for road users and maintenance personnel
- Environmental Performance
- Material sustainability and ecological impact
- Resistance to weathering and pollution
- Avoidance of negative effects on flora, fauna, and water runoff
- Test Methods
- Standardized procedures for evaluating safety and environmental features
- Clear criteria for pass/fail or classification
- Documentation and Classification
- Guidance on result reporting and classification of devices based on assessed characteristics
- Amendments for improved clarity and consistency (e.g., updated annex sub-clauses)
These areas are systematically addressed in the annexes (A-F) of the standard, providing a modular and detailed approach to each non-acoustic aspect.
Applications
EN 1794-2:2024/prA1 is essential for all stakeholders involved in noise reduction along roadways, including:
- Manufacturers and Suppliers
- Designing and producing barriers or devices that adhere to current European non-acoustic requirements
- Infrastructure Planners and Civil Engineers
- Specifying appropriate noise reducing devices for highway and urban roadside projects
- Ensuring long-term project sustainability and public safety
- Regulatory and Public Authorities
- Assessing compliance of installed devices with non-acoustic safety and environmental regulations
- Promoting environmentally responsible infrastructure investment
By applying this standard, organizations improve the quality, durability, and acceptability of road noise mitigation solutions, minimize environmental impact, and protect road users.
