  "text": "The tow vehicle or the tyre test vehicle shall have the capability of maintaining the specified speed of 65 ± 2 km/h even under the maximum braking forces.\nThe trailer or the tyre test vehicle shall be equipped with one place where the tyre can be fitted for measurement purposes hereafter called ‘ test position ’ and the following accessories:\n(i) equipment to activate brakes in the test position;\n(ii) a water tank to store sufficient water to supply the road surface wetting system, unless external watering is used;\n(iii) recording equipment to record signals from transducers installed at the test position and to monitor water application rate if the self-watering option is used.\nThe maximum variation of toe-settings and camber angle for the test position shall be within ± 0,5 ° with maximum vertical load. Suspension arms and bushings shall have sufficient rigidity necessary to minimise free play and ensure compliance under application of maximum braking forces. The suspension system shall provide adequate load-carrying capacity and be of such a design as to isolate suspension resonance.\nThe test position shall be equipped with a typical or special automotive brake system which can apply sufficient braking torque to produce the maximum value of braking test wheel longitudinal force at the conditions specified.\nThe brake application system shall be able to control the time interval between initial brake application and peak longitudinal force as specified in section 4.2.7.1.\nThe trailer or the tyre test vehicle shall be designed to accommodate the range of candidate tyre sizes to be tested.\nThe trailer or the tyre test vehicle shall have provisions for adjustment of vertical load as specified in section 4.2.5.2.",
