MT 60940 - TC 40/MT 60940

IEC 60940:2026 establishes general rules and safety requirements on the application of capacitors, resistors, inductors, and complete filter units for electromagnetic interference suppression which will be connected to an AC mains or other supply (DC or AC) with a nominal voltage not exceeding 1 000 V AC having a nominal frequency not exceeding 400 Hz, or 1 500 V DC.
It facilitates drafters of product safety standards and other stakeholders such as designers, manufacturers, service providers, policy makers and regulators to consider safety aspects for the intended use and the reasonably foreseeable misuse of these components in its products and systems and apply risk reduction measures to achieve a tolerable risk level.
This third edition includes the following significant technical changes with respect to the previous edition:
a) new title to change the document from “guidance” into “general rules and safety requirements;
b) new content added (Clause 5 to Clause 9);
c) the previous edition is partly contained in Clause 4.

IEC 60940:2015 provides guidance applicable to information on application of capacitors, resistors, inductors, and complete filter units for electromagnetic interference suppression. This second edition cancels and replaces the first edition published in 1988. This second edition is a result of maintenance activities related to the previous edition. All changes that have been agreed upon can be categorized as minor revisions.
