IEC 61347-1:2007

This part of IEC 61347 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 standard also covers lamp controlgear for lamps which are not yet standardized. Tests dealt with in this standard are type tests. Requirements for testing individual lamp controlgear during production are not included. This part 1 is to be used in conjunction with the appropriate part 2, which contains clauses to supplement or modify the corresponding clauses in part 1, to provide the relevant requirements for each type of product. This first edition of IEC 61347-1, together with parts 1 to 9 of IEC 61347-2, cancels and replaces IEC 60920, IEC 60922, IEC 60924, IEC 60926, IEC 60928 and IEC 61046, and constitute a minor revision. The relationship between the parts that make up IEC 61347-2 and the IEC standards they replace is detailed as follows: IEC 61347-2-1 replaces IEC 60926 IEC 61347-2-2 replaces IEC 61046 IEC 61347-2-3 replaces IEC 60928 IEC 61347-2-4 replaces IEC 60924, Section 3 IEC 61347-2-5 replaces IEC 60924, Section 4 IEC 61347-2-6 replaces IEC 60924, Section 5 IEC 61347-2-7 replaces IEC 60924, Section 6 IEC 61347-2-8 replaces IEC 60920 IEC 61347-2-9 replaces IEC 60922

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.
