For the purposes of this part, the following d

23、efinitions apply: 3.1 short wave infra-red emitter an emitter which radiates mainly in the short wave infra-red, i.e.having a maximum emission at the wavelength equal to or less than24m and for which light production is not of direct interest 3.2 bulb reflector infra-red lamp an infra-red emitter co

24、mprising a tungsten filament enclosed in a hermetically sealed bulb containing an inert gas and in which part of the bulb is shaped and metallized so as to direct radiation 3.3 short wave tubular infra-red emitter an infra-red emitter for operation at high temperature comprising a linear filament en

25、closed in a hermetically sealed infra-red transmitting tube which may contain an inert or predominantly inert gas with the linear tungsten filament held parallel to the axis of the tube 3.4 rated wattage the wattage marked on the emitter 3.5 rated voltage the voltage for which the emitter is designe

26、d 3.6 rated voltage range the interval between the highest and lowest voltages specified and indicated on the emitter by the manufacturer 3.7 design voltage the voltage at which the objective characteristics are obtained NOTE 1If there is only one rated voltage, the design voltage is the rated volta

27、ge. NOTE 2If the emitter is marked with a dual rated voltage (rated voltage range), the design voltage is to be the mean value of the rated voltage range.EN60240-1:1994 4 BSI 11-1999 3.8 maximum permissible cap and bulb temperatures temperature on cap and bulb of the infra-red emitter which should n

28、ot be exceeded when operated under any service condition. For measurement see IEC598 3.9 maximum permissible pinch temperature temperature of the pinch which should not be exceeded when operated under any service condition. For measurement, see IEC682 4 Marking The following information shall be mar

29、ked on the emitter: a) Mark of origin (this may take the form of a trade mark, the manufacturers name, or the name of the responsible supplier), and manufacturers type reference. b) Rated wattage. c) Rated voltage or rated voltage range. d) For bulb reflector infra-red lamps only, the marking IR (in

30、fra-red): IR1 for low-temperature service; IR2 for high-temperature service; IR3 for very high-temperature service (see note2 to the Table in5.1). For bulb reflector infra-red lamps, the maximum cap temperature shall be quoted in the manufacturers catalogue.EN60240-1:1994 BSI 11-1999 5 5 Characteris

The requirement for

35、emitters is that they can be mounted on pins fixed at a nominal dimension L 3 . The holders should be floating over1mm minimum to allow for the difference in expansion between the emitter and the material of the oven structure. 3)Maximum diameter of holder pins is4,5mm.
