24、mperature rise of the lamp cap is, in practice, very dependent on the mounting of the lamp and the condition of the cap. For this reason, it has been necessary to define a method of measurement based on the use of a standard test lampholder. The temperature rise %t smeasured on the standard test lam

25、pholder is taken as the lamp cap temperature rise for the purpose of this standard. Compared with the measurement of the temperature rise of the bare lamp cap, the measurement of the temperature rise of a standard test lampholder has the following advantages: a better approximation to actual operati

26、ng conditions; improved reproducibility, as there is less influence from lamp cap material, finish and surface conditions (which also have little influence on actual operating conditions); levelling (or averaging) of the temperatures of various parts of the cap, giving a better overall picture of th

27、e heat transferred from the lamp to the luminaire; reduced duration of measurements, as the thermocouple is fixed permanently to the test lampholder. 1 General 1.1 Scope This International Standard describes the standard method of measurement of lamp cap temperature rise which is to be used when tes

28、ting tungsten filament or discharge lamps for compliance with the limits. Temperature-rise limits for particular lamp types are, for example, listed in IEC60432. It covers the method of test and the specifications for test lampholders for lamps fitted with various sizes of ES and BC caps. This metho

29、d has been used widely for incandescent lamps but its application is not limited to that kind of lamp. 1.2 Normative reference The following normative document contains provisions which, through reference in this text, constitutes provisions of this International Standard. At the time of publication

30、, the edition indicated was valid. All normative documents are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent edition of the normative document indicated below. Members of IEC and ISO maint

31、ain registers of currently valid International Standards. IEC60432, Safety specification for incandescent lamps. 2 Definitions For the purposes of this International Standard, the following definitions apply: 2.1 temperature rise of cap surface temperature rise of a standard test lampholder fitted t

32、o the lamp cap, when measured under conditions specified in this standard 2.2 equilibrium temperature (t m ) steady-state temperature of a standard test lampholder reached after a sufficient lamp burning time NOTEThe measuring accuracy should be 1 C. 3 General conditions for measurements 3.1 Ageing

33、and stabilizing For these measurements, no previous ageing of the lamp is required. Sufficient stability of the lamp is achieved during the time necessary to reach the equilibrium temperature in the test enclosure. 3.2 Supply voltage a) For lamps intended to be connected directly to the supply, meas

34、urement shall be made at rated voltage, the supply voltage being maintained constant within 0,5%. b) For lamps intended to be connected to the supply through a ballast, measurements shall be made at the rated voltage of the ballast, the supply voltage being maintained constant within 0,5%. Measureme

35、nts shall be made using a reference ballast or a production ballast which at the calibration current has an impedance within1% of the reference ballast. If the lamp is marked with a voltage range the test procedure of IEC60432 shall apply, unless a different procedure is called for in another public

36、ation. 3.3 Ambient and reference temperatures The reference temperature for defining cap temperature rise is25 C. However, it is possible for the measurements to be made at an ambient temperature (t amb ) within the range of15 C to40 C unless otherwise specified in the relevant lamp data sheet; that

37、 is, the temperature within the test enclosure, during the measurement cycle, shall remain within this range for the results to be meaningful. A special test enclosure, described in4.1, is used to maintain the ambient temperature at a sufficiently constant value.EN60360:1998 4 BSI 02-2000 If the tem

38、perature in the test enclosure differs from25 C, the value %t mmeasured shall be converted to a temperature rise relevant to an ambient of25 C in accordance with the following formula: where NOTEThe above formula is valid for any ambient temperature between15 C and40 C. 4 Test requirements Temperatu

39、re measurements shall be made in a draught-free test enclosure. 4.1 Test enclosure The draught-proof enclosure is rectangular, with a double skin on the top and on at least three sides, and with a solid base. The double skins are of perforated metal, spaced apart approximately150mm, with regular per

40、forations of1mm to2mm diameter, occupying about40% of the whole area of each skin. The internal surfaces are painted with a matt paint. The dimensions of the enclosure shall be such that the ambient temperature within the test enclosure will not exceed40 C while the test is being run. To achieve thi

41、s condition, the three principal internal dimensions shall be preferably at least900mm. There should be a clearance of at least200mm between any part of the lamp and the inside of the enclosure. Alternative constructions for draught-proof enclosures are suitable if it is established that similar tes

42、t results are obtained. NOTEFor production surveillance conditions, a smaller enclosure of500mm 500mm 500mm may be used, providing the internal ambient temperature does not exceed40 C during temperature measurement, the lamp being mounted in the centre of the enclosure. The internal ambient temperat

43、ure shall be measured with a thermometer screened from direct radiation from the test lamp. The thermometer is to be placed level with the lamp about halfway between the lamp and the wall. 4.2 Suspension methods The standard measurement position shall be cap-up unless another burning position is spe

44、cified for the relevant lamp. The suspension of the lamp shall not affect the convection around the lamp in any adverse manner. 4.2.1 Cap-up The test-lamp, assembled in the test lampholder as described in clause8, shall be suspended from the top of the enclosure directly by the supply leads. 4.2.2 C

45、ap-down This position requires a special bulb supporting system attached to the enclosure. This shall consist of three equally spaced points which are intended to support the bulb of the test lamp, assembled in the test lampholder as described in clause8, in the transition area between the major bul

46、b diameter and the neck. a) The support points shall be at least5mm away from the cap. b) The material of the support points shall be a suitable thermal insulating material. c) The area of a point that contacts the lamp bulb should be kept as small as possible to minimize heat loss errors. d) For ca

47、p-down suspension of tubular lamps, spring loading of the contact points will be necessary to provide a holding force. 5 Test lampholders 5.1 General construction Test lampholders consisting of a metallic sleeve fitted with a thermocouple have been standardized for lamps provided with various types

48、of caps. The various test lampholders shall be as specified in the relevant figures. Each test lampholder shall have a permanently attached stranded flexible wire which in the case of ES caps and single contact bayonet caps serve as one of the supply leads. A thermocouple shall be permanently attach

49、ed to the lampholder sleeve (see7.3). In addition, a spring wire shall be used around the outside of the sleeve to assure good physical contact between the sleeve and the cap of the lamp. Figure 1 shows the general construction features and assembled position of a lampholder for an ES cap. Figure 2 shows supplementary information. 5.2 Test lampholder sleeve material specification 5.2.1 Composition NOTEExamples of the above material may be found in the following standards: Germany, DIN17750, Werkst
