Incandescent Lamps - Safety Specifications - Part 2: Tungsten Halogen Lamps for Domestic and Similar General Lighting Purposes

This part of IEC 60432 specifies the safety and the related interchangeability requirements of tungsten halogen lamps for general lighting service. It covers those tungsten halogen lamps that are used as direct replacements for conventional tungsten filament lamps as well as new tungsten halogen lamps which have no correspondence in IEC 60432-1, but for which the safety and interchangeability requirements are treated by this standard in conjunction with IEC 60432-1. These tungsten halogen lamps have the following characteristics:
- rated wattage up to and including 250 W;
- rated voltage of 50 V to 250 V inclusive;
- caps B15d, B22d, E12, E14, E17, E26, E26d, E26/50x39, E27 or E27/51x39.
Lamps complying with this standard are self-shielded, but need not be marked with a special symbol. As they are direct replacements for conventional tungsten filament lamps, there will be no corresponding luminaire marking.
NOTE 1 There is no implication that a tungsten halogen lamp used as a substitute for an incandescent tungsten filament lamp would use the same bulb shape as the original incandescent lamp.
NOTE 2 There are two variations of E26 caps which are not fully compatible: E26/24 caps used in North America and E26/25 caps used in Japan.
NOTE 3 Self-shielded lamps are lamps for which the luminaire needs no protective shield.
