11、uary 2002 Foreword This British Standard has been prepared by Technical Committee CPL/34/1 and it supersedes BS 469:1960 which is withdrawn. This revision has taken the opportunity of changing the presentation of the information to reflect current international practice by the introduction of lamp d
12、ata sheets in Section 2, and of updating cross-references and drawings. 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 with a British Standard does not of itself confer im
13、munity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages 1 to 18, an inside back cover and a back cover.

General 1 1 Scope This British Standard specifies the requirements for railway signalling lamps and gives the testing procedures required to establish conformity to the requirements, based upon statistic
15、al evaluation against an acceptable non-conformity level. 2 Normative references This British Standard incorporates, by reference, provisions from specific editions of other publications. These normative references are cited at the appropriate points in the text and the publications are listed on pa
16、ge 18. Subsequent amendments to, or revisions of, any of these publications apply to this British Standard only when incorporated in it by updating or revision. 3 Definitions For the purposes of this British Standard the following definitions apply. 3.1 rated value the value specified in the relevan
17、t lamp standard or assigned by the manufacturer or responsible supplier 3.2 double-pole lamp a double-filament lamp in which both filaments are connected permanently in parallel 3.3 triple-pole lamp a double-filament lamp in which one end of each filament is connected to the cap shell and the other
18、ends of the filaments are connected one to each contact plate 3.4 light centre the geometrical centre of the incandescent part of a filament (main or auxiliary) or, in the case of bow filaments, the centre of the enclosing rectangle 3.5 reference plane a plane defined with reference to the cap or ba
19、se and with respect to which the position of certain parts of the lamp are measured 3.6 reference axis an axis defined with reference to the cap or base and with respect to which the position of certain parts of the lamp are measured 3.7 light centre length the distance between the centre of the rec
20、tangle enclosing the luminous filament section or a defined point of the filament and the reference plane 3.8 axial error (lateral deviation) in lamps other than those with offset filaments, the perpendicular distance of the light centre from the axis of the cap 3.9 initial readings the photometric
21、and electrical values measured at the end of the ageing period 3.10 life the total time for which a lamp has been operated before it becomes useless, or, according to specific criteria, is considered to be soBS 469:1995 2 BSI 18 January 2002 Section 1 3.11 batch all the lamps of a single type manufa
22、ctured by a single manufacturer, within the same production time frame and under environmental and production conditions which can be considered to be uniform 3.12 inspection test quantity (ITQ) the sample of lamps required to be inspected for conformity to mechanical and physical requirements 3.13
23、rating test quantity (RTQ) the sample of lamps required to be tested for electrical and photometric values 3.14 life test quantity (LTQ) the sample of lamps required to be tested for conformity to the life requirement 3.15 reference number an identification number defining a type of lamp, with regar
24、d to the particular requirements of this specification 4 Requirements 4.1 General Lamps shall be so designed and constructed that in normal use they present no danger to the user or their surroundings. 4.2 Marking The following information shall be marked on the lamps, and shall remain legible when
25、tested in accordance with A.2.2: a) reference number; b) rated voltage; c) rated wattage; d) trade name or mark of the manufacturer or responsible vendor; e) month and year of manufacture 1) ; f) where specified on the lamp data sheet, the letter “M” shall also appear on the lamp cap adjacent to the
26、 main filament contact plate. Any additional marking shall be such as to allow no confusion with these markings. Where, on some types of lamps, limited space is available for marking, the reference number and month and year of manufacture shall appear on the immediate lamp wrapping or container. 4.3
27、 Dimensions and filament arrangements The dimensions and filament arrangements shall be as specified in the respective lamp data sheets (see Section 2). 4.4 Caps Where applicable, the dimensions of caps of finished lamps shall conform to BS EN 60061-1 or BS 1050. The shell of bayonet caps shall be o
28、f brass or nickel plated brass. Caps shall be so constructed and attached to the bulbs that during the inspection test and on completion of the life test they shall withstand a torsion of either 2.8 Nm in the case of B22 (3-pin) caps, or 1.1 Nm in the case of B15 caps, in both cases when these torsi
29、ons are applied using the holders shown in Figure 1 and Figure 2 respectively. 1) It is permissible to use an abbreviated code.BS 469:1995 BSI 18 January 2002 3 Section 1 4.5 Insulation resistance Except in the case of the triple-pole lamps, the insulation resistance between the contact plates and t
30、he shell of the cap shall be not less than 50 M in the case of B22 (3-pin) caps and 10 M in the case of B15 caps. 4.6 Cap solder The cap solder shall be applied in such quantity as to allow proper engagement of the cap in the lampholder. Contact plates shall be evenly soldered to ensure satisfactory
31、 electrical contact in the appropriate lampholder. If hard solder is used, it shall have a softening point in excess of 290 C. NOTE 1 The use of hard solder should be by agreement between the manufacturer or responsible vendor and the user. NOTE 2 It is not essential that the surface of the contact
32、plate should be completely covered with solder. 4.7 Initial readings The electrical and photometric ratings shall conform to the values given on the relevant data sheets (see Section 2). 4.8 Life The life shall conform to the values given on the relevant data sheets (see Section 2).
