7、SI BS EN 60925:1991 ii BSI 11 July 2002 National foreword This British Standard has been prepared by Technical Subcommittee CPL/34/3 (formerly LGL/21). It is the English language version of EN 60925 “D.C. supplied electronic ballasts for tubular fluorescent lamps Performance requirements”, including
8、 amendments A1:1996 and A2:2001, which endorses IEC 60925:1989 “D.C. supplied electronic ballasts for tubular fluorescent lamps Performance requirements”, including amendments A1:1996 and A2:2001, published by the International Electrotechnical Commission (IEC). This British Standard supersedes BS 5
9、717 which is withdrawn. The foreword and preface of IEC 60925:1989 which do not form part of the text of EN 60925 have been included in National appendix NA. Annexes designated “normative” are part of the body of the standard. Annexes designated “informative” are given for information only. In this
10、standard, Annex ZA is normative. National appendix NA, National appendix NB and National appendix NC are designated “informative”. From 1 January 1997, all IEC publications have the number 60000 added to the old number. For instance, IEC 27-1 has been renumbered as IEC 60027-1. For a period of time
11、during the change over from one numbering system to the other, publications may contain identifiers from both systems.

General performance requirements 1 Scope This standard specifies general performance requirements for electronic ballasts for
37、 use on d.c. supplies having rated voltages not exceeding 250 V, associated with fluorescent lamps complying with IEC Publication 60081. It shall be read in conjunction with IEC Publication 60924. Performance requirements for electronic ballasts for general, public transport and aircraft lighting ar
38、e specified in Sections 2, Section 3 and Section 4 of this standard. NOTE 1In order to obtain satisfactory performance of fluorescent lamps with d.c. supplied electronic ballasts, it is necessary that certain features of their designs be properly co-ordinated. It is essential, therefore, that specif
39、ications for them be written in terms of measurement made against some common base-line of reference, which must be reasonably permanent and reproducible. NOTE 2These conditions may be fulfilled by reference ballasts. Moreover, the testing of ballasts for fluorescent lamps will, in general, be made
40、with reference lamps and, in particular, by comparing results obtained on such lamps with ballasts to be tested and with a reference ballast as specified in IEC Publication 60921. 2 Definitions 2.1 starting aid either a conductive strip affixed to the outer surface of a lamp, or a conductive plate w
41、hich is spaced an appropriate distance from a lamp. A starting aid can only be effective when it has an adequate potential difference from one end of the lamp 2.2 ballast lumen factor the ratio of the light output of the lamp when the ballast under test is operated at its design voltage, compared wi
42、th the light output of the same lamp operated with the appropriate reference ballast supplied at its rated voltage and frequency 2.3 reference ballast a special inductive-type ballast designed for the purpose of providing comparison standards for use in testing ballasts, and for the selection of ref
43、erence lamps. It is essentially characterized by a stable voltage-to-current ratio, which is relatively uninfluenced by variations in current, temperature and the magnetic surroundings (see Appendix B) 2.4 symmetrical inverter a definition is under consideration 2.5 asymmetrical inverter a definitio
44、n is under consideration 3 General note on tests Tests shall be made under the conditions specified in Appendix A. All ballasts specified in this standard shall comply with the requirements of IEC Publication 60924. Conformity with IEC 61547 may be declared by the manufacturer and need not form part
45、 of third party approval to this standard. 4 Marking Non-mandatory information which may be made available by the manufacturer: a) Ballast lumen factor. b) Rated output frequency (at the design voltage, with and without the lamp operating). c) Limits of the ambient temperature range within which the
46、 ballast will operate suitably at the declared rated voltage range. Licensed Copy: sheffieldun sheffieldun, na, Fri Nov 10 15:08:37 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 60925:1991 6 BSI 11 July 2002 5 Starting It may be expected that ballasts complying with this standard, when associated wi
47、th lamps which comply with IEC Publication 60081, will provide satisfactory starting (not hot restarting) of the lamp with an air temperature immediately around the lamp of between 10?C and 35 ?C at the minimum of the rated voltage range; and operation between 10?C and 50?C at other voltages within
48、the rated voltage range. The lamp electrical characteristics, on the lamp data sheets in IEC Publication 60081, apply to lamps operated with a reference ballast at its rated voltage, in an ambient temperature of 25?C. Ballasts shall provide reliable starting of the appropriate lamps over the limits
49、of the ambient temperature range declared by the manufacturer. Compliance is checked by the tests of clauses 6 and 7 unless evidence of satisfactory lamp life can be given by the manufacturer. 6 Open-circuit voltage at terminations of lamp A ballast when operated at any voltage within its rated voltage range shall provide an open-circuit voltage at the lamp terminations such that: a) the minimum r.m.s. voltage across the lamp is at least that shown in the third column of Table 1; b) the peak voltage across the lamp does not exceed that show
