IEC 61326-1 Electrical Equipment for Measurement, Control and Laboratory Use - EMC Requirements - Part 1: General Requirements

The IEC 61326-1 standard published by the International Electrotechnical Commission (IEC) describes immunity and emission requirements regarding electromagnetic compatibility (EMC) for electrical equipment operating from a supply or battery or measured circuit of less than 1000 Volt alternating current or 1500 Volt direct current. Equipment intended for professional, industrial process, industrial production and educational use is within the scope of this standard.

This standard includes measurement and test equipment, control devices, and equipment and computing devices for laboratory use and accessories intended for use with these in industrial and non-industrial locations.

Limiting unwanted electromagnetic emissions ensures that no other equipment installed in the vicinity is unduly affected by that equipment. However, the equipment must operate without undue disturbance in an electromagnetic environment typical for the locations it is intended to be operated in. In this context, three different electromagnetic environment types and immunity levels are specified in the IEC 61326-1 standard. Meanwhile, special risks such as nearby or direct lightning strikes, circuit interruptions or exceptionally high electromagnetic radiation at close range are excluded.

The following equipment falls within the scope of this standard:

• Electrical measuring and testing equipment. These devices are equipment that measures, displays or records, by electrical means, one or more electrical or non-electrical quantities, as well as non-measurement equipment such as signal generators, measurement standards, power supplies, and converters.
• Electrical control equipment. This equipment is equipment that controls one or more output quantities to certain values, where each value is determined by manual settings, local or remote programming, or by one or more input variables.
• Electrical laboratory equipment. This equipment is equipment used to prepare or analyze materials or to measure, specify or monitor physical quantities.

Among the numerous test, measurement, analysis and evaluation studies it has given for businesses in various sectors, our organization, with its trained and expert staff and advanced technological equipment, aims to meet the EMC requirements of electrical equipment for measurement, control and laboratory use within the scope of IEC 61326-1 standard. It also provides testing services.
