IEC 61347-1 Revised

IEC 61347-1:2015 specifies general and safety requirements for lamp controlgear for use on d.c. supplies up to 250 V and/or a.c. supplies up to 1 000 V at 50 Hz or 60 Hz. This third edition cancels and replaces the second edition published in 2007, Amendment 1:2010 and Amendment 2:2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) additional marking requirements;
b) additional requirements for creepage distances and clearances:
- for working voltages with operating frequencies up to 30 kHz;
- for working voltages with higher operating frequencies than 30 kHz;
- for impulse and resonance voltages ignition;
- for basic, supplementary and reinforced insulation;
- for insulation between circuits;
- for coated or potted controlgear;
c) modification of definition of ELV and FELV;
d) modification of schematic drawing, showing the different controlgear classification and insulation requirements;
e) scope extension;
f) new Annex A: test to establish whether a conductive part is a live part which may cause an electric shock;
g) new Annex M: creepage distances and clearances for controlgear where a higher degree of availability (impulse withstand category III) may be requested;
h) new Annex Q: example for Up calculation;
i) new Annex P: creepage distances and clearances and distance through isolation (DTI) for lamp controlgear which are protected against pollution by the use of coating or potting;
j) new Annex R: concept of creepage distances and clearances.
