10、PL/34/9. Optical fibre systems can provide a viable alternative solution for emergency lighting applications where the traditional electric lamp systems described in BS 5266 : Part 1 are either impractical, unsuitable or costly, for example, in explosive atmospheres, low level applications, inaccess
11、ible positions or small systems. This standard has been prepared with the specific aim of providing for interchangeability to: a) allow an emergency lighting system to be designed for an application using component parts from many different manufacturers; b) allow component parts to be upgraded to k
12、eep pace with technological advances or to be changed to accord with aesthetic requirements; c) allow the potential long life of an optical fibre system to be realized (optical fibres are virtually ageless and only the light source is liable to deteriorate with age). To avoid the introduction of new
13、 test procedures use is made of established test procedures in other British Standards wherever they are considered applicable. This standard is complementary to BS 5266 : Part 4 which provides specific guidance on design, installation and maintenance of optical fibre emergency lighting systems addi
14、tional to the general guidance and recommendations given on electric lamp emergency lighting systems in BS 5266 : Part 1. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance wi
15、th a British Standard does not itself confer immunity from legal obligations.

BSI 07-1999 1 BS 5266 : Part 5 : 1999 1 Scope This Part of BS 5266 specif
16、ies requirements for optical fibres, lightguides, connectors, emission end mounting arrangements and light sources to be used in optical fibre emergency lighting systems. Constructional and performance requirements are given, including performance under fire conditions. The standard is applicable to
17、 the component parts of an emergency lighting system using optical fibre lightguides to distribute light from a light source to one or more lighting positions remote to that light source. The standard specifies the use of optical fibres with end illumination and end emission. It is not applicable to
18、 optical fibres with end illumination and side wall emission. NOTE. This Part is to be used in conjunction with BS 5266 : Part 1 and BS 5266 : Part 4. 2 References 2.1 Normative references This Part of BS 5266 incorporates, by dated or undated reference, provisions from other publications. These nor
19、mative references are made at the appropriate places in the text and the cited publications are listed on page 12. For dated references only, the cited edition applies; any subsequent amendments to or revisions of any of the cited publications apply to this Part of BS 5266 only when incorporated in
20、the reference by amendment or revision. For undated references, the latest edition of the cited publication applies, together with any amendments. 2.2 Informative references This Part of BS 5266 refers to other publications that provide information or guidance. Editions of these publications current
21、 at the time of issue of this standard are listed on the inside back cover, but reference should be made to the latest editions. 3 Definitions For the purposes of this Part of BS 5266 the definitions given in BS 5266 : Part 1 : 1988 and BS 5266 : Part 4 : 1999 apply. 4 General NOTE. The components s
22、pecified in this Part of BS 5266 are suitable for systems to be used in air. Where component parts are to be used in any other environment, for example in an explosive atmosphere, their suitability for use in that particular environment should be checked with the manufacturer. 4.1 Working life The m
23、anufacturer shall assign a recommended working life to each component part of an optical fibre system, or assembly of such parts to allow the purchaser to plan and make provision for future replacement. The assigned working life shall be qualified by recommended maintenance where this is necessary t
24、o achieve or optimize the working life. NOTE 1. For innovative materials the results of accelerated ageing tests may be used to establish the potential working life. NOTE 2. The manufacturer should state the basis upon which the recommended working life has been established. NOTE 3. In the case of l
