IEC 61347-1:2015+A1:2017 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.
This publication is to be read in conjunction with the IEC 61347-2 series. THIS CONSOLIDATED VERSION CONSISTS OF THE THIRD EDITION (2015) AND ITS AMENDMENT 1 (2017). THEREFORE, NO NEED TO ORDER AMENDMENT IN ADDITION TO THIS PUBLICATION.
