Common use of Measurement methods Clause in Contracts

Measurement methods. 1.1. During photometric measurements, stray reflections shall be avoided by appropriate masking. 1.2. In case the results of measurements should be challenged, measurements shall be carried out in such a way as to meet the following requirements: 1.2.1. The distance of measurement shall be such that the law of the inverse of the square of the distance is applicable; 1.2.2. The measuring equipment shall be such that the angular aperture of the receiver viewed from the reference centre of the lamp is comprised between 10 angular minutes and one degree; 1.2.3. The intensity requirement for a particular direction of observation shall be deemed to be satisfied if that requirement is met in a direction deviating by not more than one-quarter of a degree from the direction of observation. 1.3. In the case where the device may be installed on the vehicle in more than one or in a field of different positions the photometric measurements shall be repeated for each position or for the extreme positions of the field of the reference axis specified by the manufacturer.
