IEC 60432-3 pdf download 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.

1.3 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 1 2 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
