12、 was prepared by the Joint Standards Australia/Standards New ZealandCommittee LG/7, Emergency Lighting in Buildings, to supersede AS/NZS 2293.1:1995Emergency lighting for buildings, Part 1: System design, installation and operation.The Standard sets out requirements for the design, installation and

13、operation of emergencyevacuation lighting systems for buildings. The objective of these requirements is to ensurethe provision of visual conditions that will alleviate panic and facilitate safe evacuation ofthe building occupants should this be necessary in the event of failure of the normallighting

14、.The objective of this edition is to introduce a number of necessary changes, particularlythose sought by the Australian Building Codes Board, with a view to the Standard beingin a form that is suitable for reference in the Building Code of Australia.Attention is drawn to the need for emergency evac

15、uation lighting systems to be regularlymaintained. In this regard it should be noted that AS/NZS 2293.2* specifies the periodicinspection and maintenance checks that should be carried out to ensure that emergencyevacuation lighting systems will continue to function effectively.For direct lighting sy

16、stems, two alternative methods are specified for deriving the requiredspacings for emergency luminaires, viz.(a) A set of rules involving the classification of emergency luminaires according totheir light output distribution (see AS/NZS 2293.3*) coupled with requirementsrelating the luminaire mounti

17、ng height and maximum spacing (see Clauses 5.3.2.2and 5.3.2.3, and Tables 5.1 to 5.5).(b) Calculations of the illuminance at floor level conducted in a specified manner(see Clause 5.3.2.4).There are differences in the way in which the methods described in Items (a) and (b) arespecified for separate

18、application in Australia and New Zealand, as explained below.For Australian purposes, the spacing rules continue to be based on illuminancecalculations in which only the luminous flux that reaches the floor directly from theemergency luminaires is taken into account.For New Zealand purposes, similar

19、 spacing rules apply to those for use in Australiaexcept that a separate luminaire classification is calculated for each room or space that isto be provided with emergency lighting. For illuminance calculations, the luminous fluxthat reaches the floor both directly and indirectly (by reflection from

20、 room surfaces) istaken into account.The above differences arise in part from different regulatory positions in Australia andNew Zealand. In particular, the different requirements arise from the following:(i) In New Zealand The underlying basis for the requirements is the provision of anilluminance

21、of not less than 1 lx at any point, as required by the New ZealandBuilding Code. Both the direct and inter-reflected luminous flux components aretaken into account.(ii) In Australia The underlying basis for the requirements is the provision of anilluminance not less than 0.2 lx at the mid-point betw

22、een adjacent luminaires. Onlythe direct component of luminous flux is taken into account.* AS/NZS2293 Emergency evacuation lighting for buildings2293.2 Part 2: Inspection and maintenance2293.3 Part 3: Emergency luminaires and exit signsAccessed by ISONET - CHINA STATE BUREAU OF TECHNICAL SUPERVIS on

23、 14 Feb 2006 AVAILABLE SUPERSEDED3 AS/NZS 2293.1:1998The differences between the New Zealand and Australian positions are, in practice, not aslarge as they appear. For a number of practical reasons, emergency lighting systemsdesigned in accordance with the Australian spacing rules (i.e. Tables 5.1 t

24、o 5.5) have, bymeasurement, been observed to provide illuminances comparable to those required by theNew Zealand Building Code.Differences also exist with respect to the installation of exit signs. For Australia, therequirements of Clause 5.6 are similar to those of AS 2293.11987 but with somechange

25、s. For New Zealand, Clause 5.7 requires compliance with Approved Document F8of the New Zealand Building Code.The abovementioned differences will be given further attention in a future revision of theStandard, having regard to any developments with respect to internationalrecommendations covering thi

26、s subject.The terms normative and informative have been used in this Standard to define theapplication of the appendix to which they apply. A normative appendix is an integralpart of a Standard, whereas an informative appendix is only for information andguidance. Copyright STANDARDS AUSTRALIA/ STAND

40、RDThe term emergency lighting is commonly used to refer to the following types oflighting systems, one or more of which may be provided in a building to guard against thepossible loss of the normal lighting:(a) Standby lighting Standby lighting systems generally provide relatively highlighting level

41、s, which will permit normal activities to continue.(b) Safety lighting Safety lighting systems are intended to ensure the safety of workersin proximity to hazardous equipment or processes.(c) Evacuation or escape lighting Evacuation or escape lighting systems are intendedto provide visual conditions

42、 that will permit the safe evacuation of people frombuildings.This Standard is concerned only with emergency evacuation or escape lighting. Theemergency lighting required by this Standard may be provided either by central systems*or single-point systems*, or by a combination of the two. Both systems

43、 have particularadvantages and disadvantages; consequently, no recommendation is made as to whichshould be employed.Attention is drawn to the fact that the reflectance of the main interior surfaces (especiallywalls and other vertical surfaces) will significantly influence the visual conditionsprovid

44、ed by an emergency lighting installation. It is therefore recommended that thecolour of these surfaces be as light in tone as practicable.It is recognized that the presence of smoke will have a detrimental effect on the visualconditions provided by emergency lighting. The Committee is of the view th

45、at there is nopractical way of ensuring that the lighting system will continue to be effective undersmoke conditions, and that dependence must be placed on other measures such as buildingconstruction and ventilation to keep escape paths as free as possible from smoke.There are developing techniques

46、(e.g. wayfinding systems) that, when applied to escaperoutes in addition to conventional emergency evacuation lighting, can enhance the visualguidance afforded during an emergency involving loss of the normal lighting. Thesetechniques are not covered in this Standard.The nature of an emergency light

47、ing system is such that one can never predict when itmay be called upon to function. Consequently, although it is important that the system iscorrectly installed and initially operates satisfactorily, it is equally important that regularinspection and maintenance procedures are instituted to ensure

48、that the system will be in astate of readiness for operation at all times. The necessary procedures are set out inAS/NZS 2293.2, Emergency evacuation lighting for buildings , Part 2: Inspection andmaintenance.* See relevant definitions in Clause 1.3.Accessed by ISONET - CHINA STATE BUREAU OF TECHNIC
