25、luence of heat conducted through the lamp cap as well as of convection. For a description of the origin and philosophy of this standard seeAnnex A. Where H.T.S. lamps are not available, an alternative heat test source (A.H.T.S.) lamp may be used. A guideline for the selection and preparation of such

26、 lamps is given in Annex B of IEC598-1. Some consideration has been given to radiation test sources (R.T.S.) in Annex A. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard.

Experience has shown that the influence of the wattage tolerance on the temperature measured at the bifurcation point of the luminaire is1,5 times greater than that of the cap temperature rise tolerance. This allows a w

39、idening of the cap temperature rise tolerance thus enabling a greater number of lamps to be selected as H.T.S. The area enclosed by A, B, C, D, E and F has been chosen to allow for the tolerance spread of cap temperature rise to be greater than the spread of wattage tolerance. Figure 1 Tolerances on

40、 wattage and lamp cap temperature riseEN60634:1995 BSI 01-2000 5 Annex A (normative) Survey of the origin and development of heat test source lamps A.1 Introduction Luminaires for incandescent lamps must satisfy various safety requirements. Two of the most important requirements are that the user mu

41、st be safeguarded against accidental contact with live parts and against fire hazard. This necessitates stringent limits with regard to temperatures that arise during operation (seeIEC598-1). The temperature limits applicable to the materials used in the luminaire shall not be exceeded in order to p

42、revent premature ageing, melting or shrinking of parts providing protection against electric contact or parts holding current-carrying parts in position. To check this, it is necessary that luminaires should be submitted to thermal tests during type testing. For such tests, two types of test lamps a

43、re generally necessary, namely: heat test source (H.T.S.) lamps, to check primarily the effect of heat conducted through the lamp cap on the lampholder and its wiring; radiation test source (R.T.S.) lamps, in order to check the effect of radiated energy on the temperature of other parts of the lumin

44、aire. For this purpose, a commercial lamp of the relevant bulb finish and shape, dimensions, cap and rated voltage should be taken. It is essential that the bulb is clean and free of extraneous markings, coating and the like. It is also necessary to give some consideration to the filament configurat

45、ion for LV(100V130V) G.L.S. lamps since some designs use axial, while others use transverse or wreath filaments, which could produce different temperature patterns in luminaires. In the case of reflectors or bowl-mirror lamps, these can also be used as R.T.S. lamps, but in a version where the non-re

46、flector part is clear (if such a version is available commercially). Radiation test source (R.T.S.) lamps do not need to have controlled %t s . A.2 Basic rules for the H.T.S. system The H.T.S. and the corresponding temperature measurement of luminaires are based on the following fundamental rules. 1

47、) H.T.S. lamps are basically defined by rated wattage, dimensions, type of cap and cap temperature rise. 2) The method of measuring the lamp cap temperature rise %t s(sleeve method) specified in IEC360. 3) Maximum average cap temperature rises have been specified in IEC432 for incandescent productio

48、n lamps of various rated wattages. 4) For such rated wattages H.T.S. lamps are intended to represent the lamps having the highest permissible average cap temperature rises for the relevant rating. 5) Luminaires shall be marked with the maximum rated wattage of the lamp(s) to be used. A.3 General con

49、siderations 1) The basis of the CEE/IEC1963 “Gentlemens agreement” was that existing good practice for lamps should not have to be modified as a consequence of the new requirements. This basis still holds good today. 2) The CEE/IEC1963 agreement was laid down in detail only for pear-shaped lamps for mains supply with E27 caps in the following ratings:60W,100W,150W,200W and300W. Subsequently, values were derived for lamps with the ratings60W,100W and150W but capped with B22. 3) Lamps other than those mentioned in item2) are subject
