Omfang

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.
