Luminaires Part 2-20: Particular requirements Lighting chains

Scope

This section of IEC 60598-2 specifies requirements for lighting chains fitted with series- or parallel- or a combination of series/parallel-connected incandescent lamps for use either indoors or outdoors on supply voltages not exceeding 250 V.
NOTE 1 A Christmas tree chain is an example of a lighting chain fitted with series or series/parallel connected lamps. A chain for illuminating ski-tracks or promenades is an example of a lighting chain fitted with parallel connected lamps.$
A chain for illuminating ski-tracks or promenades is an example of a lighting chain fitted with parallel connected lamps.
NOTE 2 For lighting chains fitted with lampholders of the push-in type, the appropriate requirements of this section apply.
NOTE 3 In some countries the term “strings” is used instead of “chains”.
#NOTE 4 For lighting chains with non-standardized lamps (e.g. lamps of the push-in type) the lamps are regarded as part of the lighting chain and consequently included in the testing (and thereby in the test certificate, if any).
