33、 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 which comply with this standard, when associated with la

34、mps 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 around the lamps between 10 C and 35 C and for voltages b

35、etween 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” having particular characteristics which are stable and r

36、eproducible. 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 generally be made with reference lamps and, in particula

37、r, 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 reference ballast construction and performance which are cons

38、idered 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 a measurement in a reference ballast circuit that mak

39、es 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 without a starter, to include provision for two alternat

40、ive 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 appraisal should be stated by the manufacturer. Two alternati

41、ve 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 used. Page 5EN 60921:2004Licensed Copy: Wang Bin, na, T

NOTE The requirements and tolerances permitted by this standard are based on testing of a type test sample

49、submitted by the manufacturer for that purpose. In principle this type test sample should consist of units having characteristics 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 production.
