Division 5.3.5

The braking force distribution of the service braking system shall be by design such that during braking with the service brake system on surfaces with different coefficients of friction of split-μ 0,2/0,8 a minimum deceleration can be achieved that is at least 55 % of the mean fully deceleration dm of the service braking system prescribed for the respective vehicle class (see point 6.3). This can be proven by calculations; in this case the rolling resistance shall not be taken into consideration.
