Overview
IEC 61326-2-6:2012 is an international standard published by the International Electrotechnical Commission (IEC) that defines the electromagnetic compatibility (EMC) requirements specific to in vitro diagnostic (IVD) medical equipment. This standard outlines minimum immunity and emission criteria to ensure that IVD devices operate safely and effectively within their electromagnetic environment. It accounts for the unique operational characteristics and environments of IVD medical equipment, providing essential guidelines to manufacturers, testing laboratories, and regulatory bodies.
As a part of the IEC 61326 series, this document complements IEC 61326-1:2012, which sets general EMC requirements for electrical equipment used in measurement, control, and laboratory applications. IEC 61326-2-6:2012 is a technical revision of the first edition from 2005 and integrates updated requirements aligned with the latest industry practices.
