This document (EN 13201-2:2015) 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 document defines quality characteristics which are specified as lighting classes for road lighting aiming at the visual needs of road users, and it considers environmental aspects of road lighting. A lighting class is defined by a set of photometric requirements aiming at the visual needs of certain road users in certain types of road areas and environment. The needs can vary at different periods during the night and also in different seasons of the year, thus the recommendations may vary during these periods. The purpose of introducing lighting classes is to make it easier to develop and use road lighting products and services in CEN member countries. The lighting classes have been defined with consideration of road lighting standards in these countries and the lighting classes defined in CIE 115:2010 (2nd Edition) aiming at harmonization of requirements where possible. However, specific circumstances concerned with the road layout, use and national approaches based on traditional, climatic or other conditions could require different values of the uniformities. Not all the classes describe in this standard should be applied in a given country.
