prEN IEC 60598-2-20:2026

This part of IEC 60598 specifies requirements for lighting chains with electric light sources for use either indoors or outdoors on supply voltages not exceeding 250 V.
Luminaires provided with fixed or detachable attachments, for example ornamental or decorative, are covered by this document. Lighting chains fitted with lampholders of the push-in type, are covered by this document.
For lighting chains with non-standardized light sources (e.g. lamps of the push-in type) the light sources are regarded as a part of the luminaire and consequently included in the testing.
This document does not apply to rope lights, as specified in IEC 60598-2-21
NOTE 1 In some countries the term "strings" is used instead of "chains".
NOTE 2  Where the term “luminaire” is used within this document it means lighting chains.
