1. Capacity of energy storage devices (Energy reservoirs)

1.1.General requirements
1.1.1.Vehicles on which the operation of the braking system depends on the use of compressed air shall be fitted with reservoirs of a capacity meeting the requirements laid down in points 1.2 and 1.3.
1.1.2.However, the reservoirs shall not be required to be of a prescribed capacity if the braking system is such that in the absence of any energy reserve it is possible with the service braking system control device to achieve a braking performance at least equal to that prescribed for the secondary braking system.
1.1.3.When verifying compliance with the requirements laid down in points 1.2 and 1.3 the brakes shall be adjusted as closely as possible.
1.2.Vehicles of category T
1.2.1.The air brake reservoirs of vehicles shall be so designed that after eight full-stroke actuations of the service braking system control device, the pressure remaining in the air brake reservoir shall be not less than the pressure required to obtain the specified secondary braking performance.
1.2.2.During the test, the following requirements shall be satisfied:
1.2.2.1.

The initial pressure in the reservoirs shall be that indicated by the manufacturer. This pressure shall be such as to enable the prescribed performance for the service braking system to be achieved. The initial pressure shall be stated in the information document.

1.2.2.2.

The reservoir or reservoirs shall not be replenished; in addition, the reservoir or reservoirs of auxiliary equipment shall be isolated.

1.2.2.3.

In the case of vehicles authorised to tow a vehicle, the supply line shall be blocked off and a reservoir of 0,5 litre capacity shall be connected to the control line. The pressure in this reservoir shall be exhausted before each actuation of the brakes. After the test referred to in point 1.2.1 the pressure in the control line shall not be less than one half of the pressure obtained at the first brake application.

1.3.Vehicles of categories R and S
1.3.1.Reservoirs fitted to towed vehicles shall be such that after eight full-stroke actuations of the tractor's service braking system, the pressure supplied to the operating parts using it does not fall below a level equivalent to one-half of the figure obtained at the first brake application and without actuating either the automatic or the parking braking system of the towed vehicle.
1.3.2.During the test, the following requirements shall be satisfied:
1.3.2.1.

The pressure in the reservoirs at the beginning of the test shall be 850 kPa.

1.3.2.2.

The supply line shall be blocked off; in addition, the auxiliary equipment reservoirs shall be isolated.

1.3.2.3.

The reservoir shall not be replenished during the test.

1.3.2.4.

At each brake application, the pressure in the control line shall be 750 kPa.

1.3.2.5.

At each brake application, the digital demand value in the electric control line shall be corresponding to a pneumatic pressure of 750 kPa.
