IEC 61326-1 sets out requirements for immunity and emissions regarding electromagnetic compatibility (EMC) for electrical equipment. It applies to equipment that uses a power supply or battery with less than 1,000 volts AC or 1,500 volts DC, or from the circuit being measured. Which equipment does IEC 61326-1 cover? A range of equipment and computing devices, such as measurement and testing equipment, control systems, laboratory equipment and other accessories.
The equipment should be able to operate without significant degradation in typical electromagnetic environments – professional, industrial, and educational settings, and in both industrial and non-industrial locations. The standard specifies three different types of electromagnetic environments and the required levels of immunity.
– basic electromagnetic environment,
– industrial electromagnetic environment,
– controlled electromagnetic environment.
However, it does not cover special risks, such as lightning strikes, circuit breaking, or high levels of electromagnetic radiation in close proximity. The text of the international standard has been approved in Europe as EN IEC 61326-1:2021 without any changes and it supersedes the standard EN 61326-1:2013.
