The IEC published Edition 4.0 of IEC 61326-2-6 on 18 June 2025; it applies to the basic safety and essential performance of in-vitro diagnostic (IVD) medical electrical equipment in the presence of electromagnetic disturbances.
The main technical change is a revision of test levels and documentation requirements for immunity and emissions (i.e., updated EMC test levels and reporting expectations). Manufacturers of IVD medical devices should treat this as a substantive update to how EMC performance is demonstrated and recorded.
