20、he 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 As measured on the standard test lampholder is taken as the lamp cap temperature rise for the purpose of this standard.

21、Compared with the measurement of the temperature rise of the bare lamp cap, the measure- ment of the temperature rise of a standard test lampholder has the following advantages: - a better approximation to actual operating conditions; - improved reproducibility, as there is less influence from lamp

22、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 the heat transferred from the lamp to the luminaire; - reduced duration of mea

23、surements, as the thermocouple is fixed permanently to the test lampholder. Page 6 EN 60360:1998 STANDARD METHOD OF MEASUREMENT OF LAMP CAP TEMPERATURE RISE 1 General 1.1 Scope This International Sandard describes the standard method of measurement of lamp cap temperature rise which is to be used wh

24、en testing tungsten filament or discharge lamps for compliance with the limits. Temperature-rise limits for particular lamp types are, for example, listed in IEC 60432. It covers the method of test and the specifications for test lampholders for lamps fitted with various sizes of ES and BC caps. Thi

25、s method 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 publ

26、ication, the edition indicated was valid. All normative documents are subject to revision, and parties to agreements based on this International Standard are enc?.uraged to investigate the possibility of applying the most recent edition of the normative docgment indicated below. Members of IEC and I

27、S0 maintain registers of currently valid International Standards. IEC 60432: Safety specification for incandescent lamps 2 Definitions For the purposes of this International Sandard, the following definitions apply: 2.1 temperature rise of cap surface temperature rise of a standard test lampholder f

28、itted to the lamp cap, when measured under conditions specified in this standard 2.2 equilibrium temperature (tm) steady-state temperature of a standard test lampholder reached after a sufficient lamp burning time NOTE -The measuring accuracy should be 11 OC. 3 General conditions for measurements 3.

29、1 Ageing 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 enclosu re. Page 6 EN 60360:1998 3.2 Supply voltage a) For lamps intended to be connect

30、ed directly to the supply, measurement shall be made at rated voltage, the supply voltage being maintained constant within 10,5 %. 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 maintaine

31、d constant within t0,5 YO. Measurements shall be made using a reference ballast or a production ballast which at the calibration current has an impedance within 11 % of the reference ballast. If the lamp is marked with a voltage range the test procedure of IEC 60432 shall apply, unless a different p

32、rocedure is called for in another publication. 3.3 Ambient and reference temperatures The reference temperature for defining cap temperature rise is 25 OC. However, it is possible for the measurements to be made at an ambient temperature ( that is, the temperature within the test enclosure, during t

33、he measurement cycle, shall remain within this range for the results to be meaningful. A special test enclosure, described in 4.1, is used to maintain the ambient temperature at a sufficiently constant value. If the temperature in the test enclosure differs from 25 OC, the value At, measured shall b

34、e converted to a temperature rise relevant to an ambient of 25 OC in accordance with the following formula: where Atz5 is the temperature rise corrected to 25 OC; At, is the difference between the final equilibrium temperature and the ambient temperature, temb is the ambient temperature. tm - tarnb;

35、 NOTE - The above formula is valid for any ambient temperature between 15 OC and 40 “C. 4 Test requirements Temperature 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 side

36、s, and with a solid base. The double skins are of perforated metal, spaced apart approximately 150 mm, with regular perforations of 1 mm to 2 mm diameter, occupying about 40 YO of the whole area of each skin. The internal surfaces are painted with a matt paint. The dimensions of the enclosure shall

37、be such that the ambient temperature within the test enclosure will not exceed 40 OC while the test is being run. To achieve this condition, the three principal internal dimensions shall be preferably at least 900 mm. There should be a clearance of at least 200 mm between any part of the lamp and th

38、e inside of the enclosure. Alternative constructions for draught-proof enclosures are suitable if it is established that similar test results are obtained. STD-ES1 BS EN b03bO-ENGL 1119 Lb24bh9 07bb177 123 B Page 7 EN 60360:1998 NOTE - For production surveillance conditions, a smaller enclosure of 5

39、00 mm x 500 mm x 500 mrn may be used, providing the internal ambient temperature does not exceed 40 OC during temperature measurement, the lamp being mounted in the centre of the enclosure. The internal ambient temperature shall be measured with a thermometer screened from direct radiation from the

40、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 specified for the relevant lamp. The suspension of the lamp shall not affect the con

41、vection around the lamp in any adverse manner. 4.2.1 Cap-up The test-lamp, assembled in the test lampholder as described in clause 8, shall be suspended from the top of the enclosure directly by the supply leads. 4.2.2 Cap-down This position requires a special bulb supporting system attached to the

42、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 clause 8, in the transition area between the major bulb diameter and the neck. a) The support points shall be at least 5 mm away from

43、 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 cap-down suspension of tubular lamps, spring loading of the contact points will

44、 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 of caps. The various test lampholders shall be as specified in the relevant f

45、igures. 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 attached to the lampholder sleeve (see 7.3). In addition, a spring wire shall be us

46、ed 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 5.2.1 Composition Nickel: 99 % min. Tes

Vickers hardness: 135 f 15. 5.2.3 Thickness 0,5 mm namely, the boiling point of water and the solidification point of tin, lead and zinc. NOTE - If it is desired to calibrat

49、e the thermocouple after it has been mounted on the sleeve, only the boiling point of water should be used (in order to avoid melting the solder). 8 Assembly of the lamp and the test lampholder in the enclosure The test lampholder shall be pushed up to the rim of the cap of the lamp to be tested. See figure 1 for the typical relationship of the lampholder and lamp. For screw caps, the orientation of the lampholder with respect to the cap is determined by the side solder. Special instructions apply for the assembly of test lampholders on to various skirted caps. a) For t
