and undulations, such as dips and large cracks, are unsuitable.

       4.2.2. The road test surface has a nominal [3]/ peak braking coefficient (PBC) of 0.9, unless otherwise specified, when measured using either:

       4.2.2.1. The American Society for Testing and Materials (ASTM) E1136 standard reference test tyre, in accordance with ASTM Method E1337‑90, at a speed of 40 mph; or

       4.2.2.2. The k-test method specified in Appendix 2 to Annex 6 of this Regulation.

       4.2.3. The test surface has a consistent slope between level and 1 per cent.

       4.3. Vehicle conditions

       4.3.1. The ESC system is enabled for all testing.

       4.3.2. Vehicle mass.  The vehicle is loaded with the fuel tank filled to at least 90 per cent of capacity, and a total interior load of 168 kg comprised of the test driver, approximately 59 kg of test equipment (automated steering machine, data acquisition system and the power supply for the steering machine), and ballast as required to make up for any shortfall in the weight of test drivers and test equipment.  Where required, ballast shall be placed on the floor behind the passenger front seat or if necessary in the front passenger foot well area.  All ballast shall be secured in a way that prevents it from becoming dislodged during testing.

       4.3.3. Tyres.  The tyres are inflated to the vehicle manufacturer's recommended cold inflation pressure(s) e.g. as specified on the vehicle's placard or the tyre inflation pressure label.  Tubes may be installed to prevent tyre de-beading.

       4.3.4. Outriggers.  Outriggers may be used for testing if deemed necessary for test drivers' safety.  In this case, the following applies for vehicles with a Static Stability Factor (SSF) ≤ 1.25:

       4.3.4.1. Vehicles with a mass in running order under 1,588 kg shall be equipped with "lightweight" outriggers.  Lightweight outriggers shall be designed with a maximum mass of 27 kg and a maximum roll moment of inertia of 27 kg∙m2.

       4.3.4.2. Vehicles with a mass in running order between 1,588 kg and 2,722 kg shall be equipped with "standard" outriggers.  Standard outriggers shall be designed with a maximum mass of 32 kg and a maximum roll moment of inertia of 35.9 kg∙m2.

       4.3.4.3. Vehicles with a mass in running order equal to or greater than 2,722 kg shall be equipped with "heavy" outriggers.  Heavy outriggers shall be designed with a maximum mass of 39 kg and a maximum roll moment of inertia of 40.7 kg∙m2.

       4.3.5. Automated steering machine.  A steering robot programmed to execute the required steering pattern shall be used in paragraphs 5.5.2., 5.5.3., 5.6. and 5.9.  The steering machine shall be capable of supplying steering torques between 40 to 60 Nm.  The steering machine shall be able to apply these torques
