This document (EN 13201-5:2015) has been prepared at Joint Working Group CEN/TC 169/WG 12 of CEN/TC 169 "Light and lighting", the secretariat of which is held by DIN, and CEN/TC 226 "Road equipment", the secretariat of which is held by AFNOR (France). The responsible German committee is Working Committee NA 058-00-11 AA "FNL/FGSV 3.02 Außenbeleuchtung" ("FNL/FGSV 3.02 Exterior lightning)") at DIN Standards Committee Lightning Technology (FNL). This part of the European Standard specifies the conventions and mathematical procedures to be adopted in calculating the photometric performance of road lighting installations designed in accordance with the parameters described in EN 13201-2 to ensure that every lighting calculation is based on the same mathematical principles. The calculation methods presented allow for the calculation of the quality characteristics of road lighting according to agreed procedures, so that the results that come from different planners have a uniform basis. The design procedure of a lighting installation also requires the knowledge of the parameters involved in the described model, their tolerances and variability. These aspects are not considered in this part of EN 13201 but a procedure to analyse their contribution in the expected results is suggested in EN 13201-4 and it can also be used in the design phase.
