Division 4.3.5 Brake adhesion demand limits

For speeds between 50 and 200 km/h, the maximum adhesion coefficient demand during braking shall be no more than 0,15. For speeds above 200 km/h, the adhesion coefficient demand declines linearly to 0,10 at 350 km/h.

A train in full service condition and a normal passenger load shall be used to verify these values.
