Common use of Measurement conditions Clause in Contracts

Measurement conditions. 3.1. If a visual inspection of the dipped-beam pattern on the screen or a photometric method is used, measurement shall be carried out in a dark environment (for example, a dark room) of sufficient area to allow the vehicle and the screen to be placed as shown in Figure 1. Headlamp centres of reference shall be at a distance vfrom the screen of at least 10 m. 3.2. The ground on which measurements are made shall be as flat and horizontal as possible, so that the reproducibility of measurements of dipped-beam inclination can be assured with an accuracy of ∀ 0.5 mrad (" 0.05 per cent inclination). 3.3. If a screen is used, its marking, position and orientation in relation to the ground and to the median longitudinal plane of the vehicle, shall be such that the reproducibility of the measurement of the dipped-beam inclination can be assured with an accuracy of ∀0.5 mrad (∀0.05 per cent inclination). 3.4. During measurements, the ambient temperature shall be between 10 and 30 °C.
