BS EN 13201-4:2003

BS EN 13201-4:2003 specifies the procedures for making photometric and related measurements of road lighting installations, and gives advice on the use and selection of luminance meters and illuminance meters.

It aims to establish conventions and procedures for lighting measurements of road lighting installations.

The conventions for observer position and location of measurement points are those adopted in BS EN 13201-3. Conditions which may lead to inaccuracies are identified and precautions are given to minimize these.

A format for the presentation of measurements is also provided.
