IEC 61326: EMC Testing of Laboratory Equipment
Standard Overview
IEC 61326 (EN 61326) is an international EMC standard developed to regulate the electromagnetic compatibility (EMC) of electrical devices, specifically laboratory equipment. IEC 61326 applies to equipment developed for test and measurement and used in control or laboratory applications. The standard lists requirements for EMC testing, which include radiated susceptibility, conducted susceptibility, radiated emissions and conducted emissions tests. EN 61326 is an equivalent standard that applies to the European Union. IEC 61326 is divided into several parts:
Buy Standard
- IEC 61326-1 | General testing requirements
- IEC 61326-2-1 | Requirements specific to sensitive test equipment in EMC unprotected testing
- IEC 61326-2-2 | Requirements for monitoring equipment utilized in low-voltage distribution systems
- IEC 61326-2-3 | Requirements for transducers with remote or integrated signal conditioning
- IEC 61326-2-4 | Requirements for insulation monitoring devices per IEC 61557-8 and insulation fault location per IEC 61557-9
- IEC 61326-2-5 | Requirements for field devices with IEC 61784-1, CP 3/2 compliant field devices
- IEC 61326-3-1 | Immunity requirements for functional safety; limited to equipment designed for safety functions in industrial applications as specified by IEC 61508 with SIL 1-3
