It shall be such as to enable the prescribed service-braking performance to be achieved and shall correspond to a vacuum not exceeding 90 % of the maximum vacuum furnished by the energy source.F1The initial energy level shall be stated in the information folder.

2. 1.2.2.2.

   The reservoir(s) shall not be fed; in addition, any reservoir(s) for auxiliary equipment shall be isolated.

3. 1.2.2.3.
