Controlgear for electric light sources - Safety - Part 1: General requirements
IEC 61347-1:2024 specifies general safety requirements for controlgear for electric light sources for use on DC supplies up to 1 500 V or AC supplies up to 1 000 V at 50 Hz or 60 Hz.This fourth edition cancels and replaces the third edition published in 2015 and Amendment 1:2017. This edition constitutes a technical revision.This edition includes the following significant technical changes with respect to the previous edition:a) complete review of document structure, including but not limited to what is individually described under items b) to s);b) removal of requirements for electromagnetic controlgear;c) addition of more specific requirements for control circuit insulation and corresponding marking;d) merging of thermal test requirements for transformers into a new Clause 16;e) clarification of specifications for the moisture resistance test;f) update of the normative reference to standards of the transformer series IEC 61558;g) correction of the normative reference for PCB testing with respect to flames and fire;h) update of further normative references where appropriate;i) allowance of an alternative DC electric strength test;j) addition of specific provisions for the use of bridging capacitors;k) update of fire hazard testing requirements;l) introduction of requirements for PELV applications;m) clearance distances now generally based on peak instead of RMS voltage values;n) introduction of a new type of protected emergency lighting controlgear;o) review and clarification of touch current and voltage requirements;p) clarification of the test sequence for independent controlgear with respect to the application of the IEC 60598 series versus the IEC 61347 series;q) introduction of reduced touch voltages and currents for interrupted DC voltage applications or pulse width modulation (PWM);r) changes concerning the recommendations for electric strength routine testing;s) merging of requirements for safety isolating controlgear from former Annex L into the main body of the document;t) introduction of Annex N intended to address touch current measurement;u) introduction of Annex O intended to provide information on document reorganization.

e) clarification of specifications for the moisture resistance test;
f) update of the normative reference to standards of the transformer series IEC 61558;
g) correction of the normative reference for PCB testing with respect to flames and fire;
h) update of further normative references where appropriate;
i) allowance of an alternative DC electric strength test;
j) addition of specific provisions for the use of bridging capacitors;
k) update of fire hazard testing requirements;
l) introduction of requirements for PELV applications;
m) clearance distances now generally based on peak instead of RMS voltage values;
n) introduction of a new type of protected emergency lighting controlgear;
o) review and clarification of touch current and voltage requirements;
p) clarification of the test sequence for independent controlgear with respect to the application of the IEC 60598 series versus the IEC 61347 series;
q) introduction of reduced touch voltages and currents for interrupted DC voltage applications or pulse width modulation (PWM);
r) changes concerning the recommendations for electric strength routine testing;

Lamp controlgear - Part 1: General and safety requirements
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.
