when the ASE becomes locked minus 5 km/h.
 2  If the dimensional characteristics of the vehicle imply an overturning risk, the manufacturer shall provide to the Technical Service behaviour simulation data demonstrating a lower maximum safe speed for conducting the test. Then the Technical Service will choose this test speed.
 3  If, due to the configuration of the test site, the values of the radii cannot be observed, the tests may be carried out on tracks with other radii, (maximum variation:  25 per cent) provided that the speed is varied to obtain the transverse acceleration resulting from the radius and speed indicated in the table for the particular category of vehicle.

 The failure shall be introduced when the specified test speed has been reached. The test shall include driving in a clockwise direction, and in a counter-clockwise direction.
2.2.1.2. Transient test
2.2.1.2.1. Until uniform test procedures have been agreed, the vehicle manufacturer shall provide the Technical Services with their test procedures and results for transient behaviour of the vehicle in the case of failure.
2.3. Warning signals in case of failure.
2.3.1. Except for parts of ASE not considered susceptible to breakdown as specified in paragraph 5.3.1.1. of this Regulation, the following failure of ASE shall be clearly brought to the attention of the driver.
2.3.1.1. A general cut-off of the ASE electrical or hydraulic control.
2.3.1.2. Failure of the ASE energy supply.
2.3.1.3. A break in the external wiring of the electrical control if fitted.

Annex 5
       Provisions for trailers having hydraulic steering transmissions
1. General provisions
 Vehicles fitted with hydraulic steering transmission, in addition to the requirements given in the body of this Regulation shall also comply with the provisions of this annex.
2. Specific provisions
2.1. Performance of hydraulic lines and hose assemblies.
2.1.1. The hydraulic lines of hydraulic transmission shall be capable of a burst pressure at least four times the maximum normal service pressure (T) specified by the vehicle manufacturer. Hose assemblies shall comply with ISO Standards 1402:1994, 6605:1986 and 7751:1991.
2.2. In systems dependent on an energy supply;
2.2.1. The energy supply shall be protected from excess pressure by a pressure limiting valve which operates at the pressure T.
2.3. Protection of steering transmission;
2.3.1. The steering transmission shall be protected from excess pressure by a pressure limiting valve which operates at between 1.1 T and 2.2 T. The operating pressure of the pressure limiting valve shall be of a value that is compatible with the operating characteristics of the steering system installed on the vehicle. This shall be confirmed by the vehicle manufacturer at the time of type approval.
