Scope
ISO 14837-1
Ground-borne Vibration from Rail Systems
ISO 14837-1 establishes the fundamental framework for measuring and predicting ground-borne vibration generated by railway operations in free-field conditions. This test is essential for assessing environmental impact, particularly for urban and suburban rail networks where vibration transmission to nearby buildings is a concern. Infrastructure operators, urban planners, and environmental consultants rely on this standard to evaluate compliance with local vibration limits and to design mitigation measures. Accredited testing ensures consistent, reproducible vibration assessments that support both regulatory compliance and community health protection.
What it measures
- Vertical vibration acceleration levels (m/sยฒ or dB ref 10โปโถ m/sยฒ)
- Horizontal vibration components
- Vibration frequency content (Hz range)
- Vibration transmission to ground and surrounding structures
- Free-field vibration velocity and displacement
