5 Foreword This document (EN :2003) has been prepared by Technical Committee CEN/TC 169 Light and lighting, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 2004, and conflicting national standards shall be withdrawn at the latest by May This document EN has been worked out by the Joint Working Group of CEN/TC 169 Light and lighting and CEN/TC 226 Road Equipment, the secretariat of which is held by AFNOR. Annexes A and B are informative. This document includes a Bibliography. This standard, EN Road Lighting, consists of three parts. This document is; Part 2: Performance requirements The other parts of EN are: Part 3: Calculation of performance Part 4: Methods of measuring lighting performance According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and the United Kingdom. 3
6 Introduction 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 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 aiming at harmonization of requirements where possible. However, some lighting classes and subclasses reflect particular situations and national approaches based on traditional, climatic or other conditions. The ME classes are intended for drivers of motorized vehicles for user on traffic routes, and in some countries also residential roads, allowing medium to high driving speeds. The CE classes are also intended for drivers of motorized vehicles, but for use on conflict areas such as shopping streets, road intersections of some complexity, roundabouts and queuing areas. These classes have applications also for pedestrians and pedal cyclists. The S and A classes are intended for pedestrians and pedal cyclists for use on footways and cycleways, emergency lanes and other road areas lying separately or along the carriageway of a traffic route, residential roads, pedestrian streets, parking areas, schoolyards etc. The ES classes are intended as an additional class in situations where public lighting is necessary for the identification of persons and objects and in road areas with a higher than normal crime risk. The EV classes are intended as an additional class in situations where vertical surfaces need to be seen in such road areas as toll stations, interchange areas etc. The requirements of the lighting classes reflect the category of road user in question or the type of road area. Thus the ME classes are based on the road surface luminance, while the CE, S and A classes are based on the illumination of the road area. The S and A classes reflect different priorities to the road lighting. The ES classes are based on semi-cylindrical illuminance, while the EV classes are based on the vertical plane illuminance. The ME classes present increasingly stronger requirements in the order ME 6, ME 5, ME 1 forming steps of the lighting level as measured for instance in illuminance. The other classes are arranged in the same way, and so that their steps interlock. Environmental aspects of road lighting are considered in clause 7 in terms of day time appearance, night time appearance and light emitted in directions, where it is neither necessary nor desirable. The purpose is to point to matters that can be included in tender specifications or similar, when relevant. Installed intensity classes for the restriction of disability glare and control of obtrusive light G.1, G.2, G.3, G.4, G.5 and G.6 are introduced in the informative annex A. The use of G classes is mentioned in clause 5 for conflict areas and in clause 7 on appearance and environmental aspects. Installed glare index classes for the restriction of discomfort glare D.0, D.1, D.2, D.3, D.4, D.5 and D.6 are introduced in the informative annex A as well. These classes are intended mainly for road areas lighted for the benefit of pedestrians and pedal cyclists. Local lighting of pedestrian crossings is considered in the informative annex B. The intention of local lighting is to attract the attention of drivers of motorized vehicles to the presence of the pedestrian crossing and to illuminate pedestrians in or at the crossing area. 4
7 1 Scope This part of this European Standard defines, according to photometric requirements, lighting classes for road lighting aiming at the visual needs of road users, and it considers environmental aspects of road lighting. NOTE Installed intensity classes for the restriction of disability glare and control of obtrusive light and installed glare index classes for the restriction of discomfort glare are defined in annex A. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments). EN , Road lighting Part 3: Calculation of performance. EN , Road lighting Part 4: Methods of measuring lighting performance. 3 Terms and definitions For the purposes of this European Standard, the following terms and definitions apply. 3.1 average road surface luminance (of a carriageway of a road) ( L ) luminance of the road surface averaged over the carriageway NOTE Unit is candelas per square metre (cd/m 2 ). 3.2 longitudinal uniformity (of road surface luminance of a driving lane) ratio of the lowest to the highest road surface luminance found in a line in the centre along a driving lane 3.3 longitudinal uniformity (of road surface luminance of a carriageway) (U I ) lowest of the longitudinal uniformities of the driving lanes of the carriageway 3.4 threshold increment (TI) measure of the loss of visibility caused by the disability glare of the luminaires of a road lighting installation 3.5 surround ratio (of illumination of a carriageway of a road) (SR) average illuminance on strips just outside the edges of the carriageway in proportion to the average illuminance on strips just inside the edges 5
