31、equirements for ballasts for tubular fluorescent lamps. It should be read in conjunction with IEC 61347-2-8, with which all ballasts covered by the present standard should comply. Unless otherwise stated on the lamp data sheet mentioned in IEC 60081 and IEC 60901, it may be expected that ballasts wh

32、ich comply with this standard, when associated with lamps complying with IEC 60081 or IEC 60901, and, where appropriate, operated with a starter complying with IEC 60155 or starting devices complying with IEC 60927, will ensure satisfactory starting of the lamps at an air temperature immediately aro

33、und the lamps between 10 C and 35 C and for voltages between 92 % and 106 % of rated supply voltage, and also proper operation between 10 C and 50 C at rated supply voltage. The compatibility of lamps and ballasts is evaluated with the use of special inductive ballasts called “reference ballasts” ha

34、ving particular characteristics which are stable and reproducible. These ballasts are used when testing commercial ballasts and when selecting reference lamps. Moreover, the testing of ballasts presents particular difficulties, which require a proper definition of testing methods. Such tests will ge

35、nerally be made with reference lamps and, in particular, by comparing the results obtained when such lamps are operated on a reference ballast with the results obtained when the same lamps are operated on the ballast being tested. NOTE Requirements are also included for all those features of referen

36、ce ballast construction and performance which are considered necessary to ensure accurate and reproducible results when testing ballasts, particularly with regard to the selection of reference lamps. For checking the lamp power and current of lamps operated without a starter, this standard specifies

37、 a measurement in a reference ballast circuit that makes no provision for separate power sources to heat the cathodes during lamp operation. Although the influence on the ballast specification is small, it has nevertheless been deemed useful for some pre-heated low-voltage cathode lamps, operated wi

38、thout a starter, to include provision for two alternative methods of measurement of lamp power and current: a) measurement of lamp power and current without additional cathode heating; b) measurement of lamp power and current with additional cathode heating. The test method to be adopted for apprais

39、al should be stated by the manufacturer. Two alternative circuits are specified for the measurement of impedance at audio frequencies. The less complex circuit could be used when there is no doubt about the inductive character of the impedance. If there is any doubt, the other circuit should be be u

40、sed. Page 5EN 60921:2004BALLASTS FOR TUBULAR FLUORESCENT LAMPS PERFORMANCE REQUIREMENTS 1 Scope This standard specifies performance requirements for ballasts, excluding resistance types, for use on a.c. supplies up to 1 000 V at 50 Hz or 60 Hz, associated with tubular fluorescent lamps with pre-heat

41、ed cathodes operated with or without a starter or starting device and having rated wattages, dimensions and characteristics as specified in IEC 60081 and 60901. It applies to complete ballasts and their component parts such as resistors, transformers and capacitors. A.C. supplied electronic ballasts

42、 for tubular fluorescent lamps for high frequency operation specified in IEC 61347-2-3 are excluded from the scope of this standard. NOTE In some regions there are laws on EMC for luminaires. The controlgear also contributes to this EMC behaviour. See Bibliography for further references. 2 Normative

46、 tests 4.1 Tests according to this specification are type tests. NOTE The requirements and tolerances permitted by this standard are based on testing of a type test sample submitted by the manufacturer for that purpose. In principle this type test sample should consist of units having characteristic

47、s typical of the manufacturers production and be as close to the production centre point values as possible. It may be expected with the tolerances given in the standard that products manufactured in accordance with the type test sample will comply with the standard for the majority of the productio

48、n. Due to the production spread, it is inevitable, however, that there may sometimes be ballasts outside the specified tolerances. For guidance of sampling plans and procedures for inspection by attributes, see IEC 60410. 4.2 The tests shall be carried out in the order of the clauses, unless otherwi

49、se specified. 4.3 One specimen shall be submitted to all tests. 4.4 In general all tests are made on each type of ballast or, where a range of similar ballasts is involved, for each rated wattage in the range or on a representative selection from the range as agreed with the manufacturer. 4.5 The tests shall be made under the conditions specified in Annex A. 4.6 All ballasts specified in this standard shall comply with the requirements of IEC 61347-2-8. 5 Marking The following inf
