12、2013 (E) 3 Foreword This document (EN 1838:2013) 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, a

13、t the latest by January 2014, and conflicting national standards shall be withdrawn at the latest by January 2014. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying an

14、y or all such patent rights. This document supersedes EN 1838:1999. Users of this European Standard, prepared in the field of application of Article 153 of the Treaty on the Functioning of the European Union TFEU, should be aware that standards have no formal legal relationship with Directives which

BS EN 1838:2013EN 1838:2013 (E) 4 Introduction Emergency lightin

19、g is provided for use when the supply to the normal lighting fails and is therefore powered from a source independent of that supplying the normal lighting. For the purposes of this standard emergency lighting is regarded as a generic term of which there are a number of specific forms, as shown in F

20、igure 1. Figure 1 Specific forms of emergency lighting The overall objective of emergency escape lighting is to enable safe exit from a location in the event of failure of the normal supply. The objective of each form within this category is as follows. The objective of escape route lighting is to a

21、ssist the safe exit from a location for occupants by providing appropriate visual conditions and direction finding on escape routes and in special locations, and to ensure that fire fighting and safety equipment can be readily located and used. The objective of emergency lighting of escape route saf

22、ety signs is to provide appropriate visual conditions and direction finding to assist escape routes to be readily located and used. The objective of open area (anti-panic) lighting is to reduce the likelihood of panic and to enable safe movement of occupants towards escape routes by providing approp

23、riate visual conditions and direction finding. The flow of light for escape routes or open areas should be downward to the working plane but illumination should also be provided to any obstruction up to 2 m height above that plane. The objective of high risk task area lighting is to contribute to th

24、e safety of people involved in a potentially dangerous process or situation and to assist proper shut down procedures to be carried out for the safety of other occupants of the location. There are techniques that may be used as a supplement and when applied to escape routes in addition to convention

25、al emergency lighting luminaires can enhance their effectiveness in an emergency. These techniques are not included in this standard. Vision varies from person to person, both by the amount of light required to perceive an object clearly and in the time taken to adapt to changes in the illuminance.

26、In general, older people need more light and take a longer time to adapt to low illuminance on a hazard or escape route. Much anxiety and confusion can be alleviated by strategically placed signs indicating the way out of a location. It is very important that exits are clearly signposted and are vis

27、ible, whenever the location is occupied. BS EN 1838:2013EN 1838:2013 (E) 5 1 Scope This European Standard specifies the luminous requirements for emergency escape lighting and standby lighting systems installed in premises or locations where such systems are required. It is principally applicable to

28、 locations where the public or workers have access. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for the application of this document.

39、ensure that emergency escape lighting operates when it is required to meet legal requirements, it shall be installed, tested and maintained in accordance with EN 60598-2-22, EN 50172 and EN 62034. The requirements given in this standard are maintained minimum values and are calculated for the full r

40、ated duration period at the end of the design life of the equipment and the inter-reflected light contribution shall be ignored. The emergency lighting scheme design should be based on worst conditions (e.g. minimum light output, maximum glare limits) of the luminaires during operating life and shou

41、ld be based only on direct light from luminaires. The contributions by room surface inter-reflections should be ignored. However, in lighting systems such as indirect luminaires or uplights (used as an emergency luminaire in maintained mode) where the luminaire works in conjunction with a reflecting

42、 surface, the first reflection (based on the maintained reflectance) may be taken as direct light from the system and subsequent reflections shall be ignored. To provide visibility for evacuation purposes lighting is required in the volume of the space. Signs that are provided at all exits intended

43、to be used in an emergency and along escape routes shall be illuminated to indicate unambiguously the route of escape to a place of safety. In this standard the requirement is fulfilled by mounting the luminaires for lighting and the escape route safety signs at least 2 m above the floor. BS EN 1838

44、:2013EN 1838:2013 (E) 7 Where practical, for ease of seeing, the safety sign should be mounted not higher than 20 above the horizontal view according to the maximum viewing distance of the sign. To ensure that emergency lighting operates when required it shall be installed, tested and maintained in

45、accordance with EN 50172 and if automatic test facilities are installed they shall be in accordance with EN 62034. Where direct sight of an emergency exit is not possible, an illuminated directional sign (or series of signs) shall be provided to assist progression towards the emergency exit. An esca

46、pe lighting luminaire conforming to EN 60598-2-22 shall be sited to provide appropriate illuminance near each exit door and at positions where it is necessary to emphasize potential danger or safety equipment. The positions to be emphasized shall include the following. 4.1.2 Points of emphasis The p

47、oints of emphasis when placing lighting devices are: a) near (see NOTE 1) each exit door intended to be used in an emergency; b) near (see NOTE 1) stairs so that each flight of stairs receives direct light; c) near (see NOTE 1) any other change in level; d) Externally illuminated escape route safety

48、 signs, escape route direction signs and other safety signs needing to be illuminated under emergency lighting conditions; e) at each change of direction (see NOTE 2); f) at each intersection of corridors (see NOTE 2); g) near (see NOTE 1) to each final exit and outside the building to a place of sa

49、fety; h) near (see NOTE 1) each first aid post; so that 5 lx vertical illuminance shall be provided at the first aid box; i) near (see NOTE 1) each piece of fire fighting equipment and call point so that 5 lx vertical illuminance shall be provided at the fire alarm call points, fire fighting equipment and panel. j) near (see NOTE 1) escape equipment provided for the disabled; and k) near (see NOTE 1) disabled refuges and call point. Also to include disabled refuge two way communication systems including disabled toilet alarm call position. NOTE
