IEC 60940:2026 pdf download,Application of capacitors, resistors, inductors and complete filter units for electromagnetic interference suppression – General rules and safety requirements.
IEC 60940:2026 lays out general rules and safety requirements for applying EMI (electromagnetic interference) suppression parts in equipment connected to AC mains or other supplies (up to specified voltage and frequency limits). It covers how to use capacitors, resistors, inductors, and complete passive filter units so that a tolerable level of risk is achieved in the intended use and in reasonably foreseeable misuse. The standard is aimed at ensuring safety when these components are integrated into product designs—particularly considering electrical hazards such as insulation/withstand issues and related effects (e.g., fault conditions) and also practical aspects of mounting and integration. It provides risk-reduction-oriented guidance so that technical designers, manufacturers, and those drafting product safety standards can apply consistent safety measures when selecting and combining EMI suppression components into circuits and systems.
