Defines requirements for lighting chains fitted with series, parallel or a combination of series/parallel connected light sources for use either indoors or outdoors on supply voltages not exceeding 250 V.

This part of IEC60598 specifies requirements for lighting chains fitted with series, parallel or a combination of series/parallel connected light sources for use either indoors or outdoors on supply voltages not exceeding 250V. For combinations where rope lights (also known as sealed lighting chains) are included, see IEC60598‑2‑21 . Lighting chains provided with fixed or detachable attachments e.g. ornamental or decorative, are considered to be covered by this standard. For lighting chains fitted with lampholders of the push-in type, the appropriate requirements of this standard applies. NOTE1 A Christmas tree lighting 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. 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. NOTE2 For products where the lighting chain is permanently fixed to a frame or pre-lit Christmas tree the relevant clauses of IEC60598‑2‑4 and/or IEC60598‑2‑7 can also apply. NOTE3 In some countries the term \'strings\' is used instead of \'chains\'. NOTE4 Candlestick luminaries are tested according to IEC60598‑2‑4 .
