IEC 60432-3-2005 pdf – Incandescent lamps – Safety specifications – Part 3: Tungsten-halogen lamps (non-vehicle).
1 General 1.1 Scope This part of IEC 60432 specifies the safety requirements for single-capped and double-capped tungsten halogen lamps, having rated voltages of up to 250 V, used for the following applications: • Projection (including cinematograph and still projection) • Photographic (including studio) • Floodlighting • Special purpose • General purpose • Stage lighting This International Standard does not apply to general purpose single-capped tungsten halogen lamps, covered by IEC 60432-2, that are used as replacement for conventional tungsten filament lamps. 1.2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60050-845:1987, International Electrotechnical Vocabulary (IEV) – Chapter 845: Lighting IEC 60061-1, Lamp caps and holders together with gauges for the control of interchangeability and safety – Part 1: Lamp caps IEC 60061-3, Lamp caps and holders together with gauges for the control of interchangeability and safety – Part 3: Gauges IEC 60061-4, Lamp caps and holders together with gauges for the control of interchangeability and safety – Part 4: Guidelines and general information IEC 60357, Tungsten halogen lamps (non-vehicle) 1.3 Definitions For the purpose of this International Standard, the definitions given in IEC 60050(845), as well as the following apply:
1.3.1 tungsten halogen lamp gas-filled lamp containing halogens or halogen compounds, the filament being of tungsten 1.3.2 single-capped tungsten halogen lamp tungsten halogen lamp having a single cap or base 1.3.3 double-capped tungsten halogen lamp tungsten halogen lamp having a cap or base on each end of the lamp 1.3.4 extra low voltage tungsten halogen lamp tungsten halogen lamp with a rated voltage lower than 50 V NOTE Abbreviated: ELV tungsten halogen lamp 1.3.5 extra low voltage low-pressure tungsten halogen lamp tungsten halogen lamp with a gas pressure below a certain value and a rated voltage less than or equal to 12 V 1.3.6 self-shielded tungsten halogen lamp tungsten halogen lamp for which the luminaire needs no protective shield NOTE Abbreviated: self-shielded lamp. Examples of self-shielded tungsten halogen lamps are:  ELV tungsten halogen lamps with integral outer envelope;  ELV low-pressure tungsten halogen lamps;  mains voltage tungsten halogen lamps which conform to IEC 60432-2;  mains voltage tungsten halogen lamps which conform to the relevant clauses of this standard. 1.3.7 outer envelope transparent or translucent enclosure containing a tungsten halogen light source NOTE The enclosure can also consist of a reflector with integral front cover 1.3.8 rated voltage voltage or voltage range specified in this standard or assigned by the manufacturer or responsible vendor NOTE If lamps are marked with a voltage range, they are appropriate for use on any supply voltage within that range. 1.3.9 test voltage rated voltage unless otherwise specified NOTE If lamps are marked with a voltage range, the test voltage is the mean of the voltage range, unless otherwise specified.
1.3.10 rated wattage wattage specified in this standard or assigned by the manufacturer or responsible vendor 1.3.11 rated current current specified in this standard or assigned by the manufacturer or responsible vendor 1.3.12 test current rated current unless otherwise specified 1.3.13 specific effective radiant UV power effective power of the UV radiation of a lamp related to its luminous flux Unit: mW/klm For a reflector lamp, this is the effective irradiance of the UV radiation related to the illuminance. Unit: mW/(m 2 ·klx) NOTE The effective power (or irradiance) of the UV radiation is obtained by weighting the spectral power distribution of the lamp with the action spectrum published by the American Conference of Governmental Industrial Hygienists (ACGIH), which is endorsed by the World Health Organization (WHO) and recommended by the International Radiation Protection Association (IRPA).
