This Standard 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.
NOTE 2 For lighting chains fitted with lampholders of the push-in type, the appropriate requirements of this Standard apply.
NOTE 3 In some countries, the term "strings" is used instead of "chains".
NOTE 4 For lighting chains with non-standardised lamps (e.g. lamps of the push-in type) the lamps are regarded as a part of the lighting chain and consequently included in the testing (and thereby in the certificate, if any).
NOTE 5 The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.
IEC 60598-2-20 : 2010 Luminaires – Part 2-20 : Particular requirements – Lighting chains (MOD)
In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/IEC Guide 21-1.
