Scope
EN 12299
Measurement and Evaluation of Railway Ride Comfort
EN 12299 establishes standardised methods for measuring and evaluating passenger ride comfort in railway vehicles through vibration analysis. The standard defines vibration indices including Nmv (main index), NVA (vertical), and NVD (lateral) to objectively quantify passenger comfort levels during train operation. This test is essential for railway manufacturers and operators to ensure compliance with comfort standards, validate new vehicle designs, and support passenger satisfaction assessments. Accreditation guarantees correct instrumentation setup, accurate measurement procedures, and proper calculation of comfort indices according to European rail requirements.
What it measures
- Main ride comfort index (Nmv)
- Vertical vibration discomfort (NVA)
- Lateral vibration discomfort (NVD)
- Frequency-weighted acceleration
- Overall comfort rating
