EN 55032 Class A Conducted Emission Overview
EN 55032 (harmonized under the EU EMC Directive and aligned with CISPR 32) details the electromagnetic emission requirements for Multimedia Equipment (MME). Conducted Emission (CE) testing on AC mains ports measures the RF disturbance voltage fed back onto the power grid to ensure the protection of public power distribution systems.
Note on EN 55022 / CISPR 22: EN 55032 / CISPR 32 has officially superseded the legacy standards EN 55022 and CISPR 22. However, the conducted emission limit requirements on AC mains power ports remain completely identical between the standards, meaning the limits presented here apply equally for evaluations under EN 55022 / CISPR 22.
Class A Equipment: Designed for use in commercial, industrial or business environments. Class A limits are less stringent compared to Class B because commercial and industrial electrical environments are expected to tolerate larger ambient electromagnetic noise. Devices passing Class A limits but failing Class B cannot be marketed for residential use and must carry appropriate warnings.
