Division 6.2.1

Towed vehicles equipped with an anti-lock braking system shall be deemed acceptable when the condition ε ≥ 0,75 is satisfied, where ε represents the adhesion utilised, as defined in point 2 of Appendix 2. This condition shall be verified with the vehicle unladen, on a straight and level road with a surface having a good coefficient of adhesion.

If the coefficient of adhesion of the test track is too high, preventing the anti-lock braking system from cycling then the test may be carried out on a surface with a lower coefficient of adhesion.

In the case of trailers fitted with a brake load sensing device the pressure setting may be increased to ensure full cycling.
