       PHOTOMETRIC MEASUREMENTS

       1. When photometric measurements are taken, stray reflexions shall be avoided by appropriate masking.

       2. In the event that the results of measurements are challenged, measurements shall be taken in such a way as to meet the following requirements:

       2.1. the distance of measurement shall be such that the law of the inverse of the square of the distance is applicable;

       2.2. the measuring equipment shall be such that the angle subtended by the receiver from the reference centre of the light is between 10' and 1 degrees;

       2.3. the intensity requirement for a particular direction of observation shall be satisfied if the required intensity is obtained in a direction deviating by not more than one-quarter of a degree from the direction of observation.

       3. If visual examination of a light appears to reveal substantial local variations of intensity, a check shall be made to ensure that, outside the axes, no intensity measured within the rhombus defined
