| BSI | 2020 | 114 |
This European Standard specifies measurement conditions and procedures for measuring the photometric quality parameters of road lighting installations, i.e. the quantities that quantify their performances in accordance with EN 13201-2 lighting classes. Parameters used for quantifying the energy performance of road lighting installations are not considered. A methodology to evaluate the road lighting performances considering tolerances in the design parameters is described in the informative Annex A.
