scope:

This standard specifies methods for quantifying the effects of vehicle body motions on ride comfort for passengers and vehicle assessment with respect to ride comfort. The effect considered is:- discomfort, associated with relatively low levels of acceleration and roll velocity. Other effects, not included in the standard, are associated with higher acceleration levels:- health risk effect: physical damage and psychological deterioration. The standard applies to passengers travelling in railway vehicles on railway lines, including main, secondary and suburban lines. This standard could be used as a guide for other railway vehicles, for example locomotives, metros, trams, etc. The standard applies to passengers in good health. This standard applies to measurements of motions. It also applies to simulated motions.
