scope:

This European Standard specifies methods for quantifying the effects of car 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 scope of the standard is limited to public railway services; the standard includes railway vehicles designed for carrying passengers travelling on railway lines, including secondary and suburban lines. However, this standard can 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, but can also be used for simulations.
