not the International Standard IEC 240-1:1992 could be accepted without textual changes, has shown that no common modifications were necessary for acceptance as a European Standard The reference document was submitted to the CENELEC members for formal vote and was approved by CENELEC as EN 60240-1 on March 1994 The following dates were fixed: — latest date of publication of an identical national standard (dop) 1995-03-15 — latest date of withdrawal of conflicting national standards (dow) 1995-03-15 For products which have complied with the relevant national standard before 1995-03-15, as shown by the manufacturer or by a certification body, this previous standard may continue to apply for production until 2000-03-15 Annexes designated “normative” are part of the body of the standard In this standard, Annex ZA is normative © BSI 11-1999 EN 60240-1:1994 Scope This part of IEC 240 refers to short wave infra-red emitters for industrial heating purposes falling into two categories: a) Bulb reflector infra-red lamps b) Tubular emitters Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of IEC 240 At the time of publication, the editions indicated were valid All normative documents are subject to revision, and parties to agreements based on this part of IEC 240 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below Members of IEC and ISO maintain registers of currently valid International Standards IEC 50(841):1983, International Electrotechnical Vocabulary (IEV) — Chapter 841: Industrial electroheating IEC 61, Lamp caps and holders together with gauges for the control of interchangeability and safety IEC 598, Luminaires IEC 682:1980, Standard method of measuring the pinch temperature of quartz-tungsten-halogen lamps Definitions For definitions of fundamental and general terms in the electroheat field, refer to IEC 50 (841) For the purposes of this part, the following definitions 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 than 4m and for which light production is not of direct interest 3.2 bulb reflector infra-red lamp an infra-red emitter comprising 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 enclosed 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 designed 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 If there is only one rated voltage, the design voltage is the rated voltage NOTE If 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 © BSI 11-1999 EN 60240-1:1994 3.8 maximum permissible cap and bulb temperatures temperature on cap and bulb of the infra-red emitter which should not be exceeded when operated under any service condition For measurement see IEC 598 3.9 maximum permissible pinch temperature temperature of the pinch which should not be exceeded when operated under any service condition For measurement, see IEC 682 Marking The following information shall be marked on the emitter: a) Mark of origin (this may take the form of a trade mark, the manufacturer’s name, or the name of the responsible supplier), and manufacturer’s type reference b) Rated wattage c) Rated voltage or rated voltage range d) For bulb reflector infra-red lamps only, the marking IR (infra-red): — IR for low-temperature service; — IR for high-temperature service; — IR for very high-temperature service (see note to the Table in 5.1) For bulb reflector infra-red lamps, the maximum cap temperature shall be quoted in the manufacturer’s catalogue © BSI 11-1999 EN 60240-1:1994 Characteristics of emitters 5.1 Bulb reflector infra-red lamps Rated wattage
