IEC 61326:2002 outlines the minimum requirements for immunity and emissions related to electromagnetic compatibility (EMC) for electrical equipment, operating from a supply of less than 1000V AC or 1500V DC or from the circuit being measured. It is intended for professional, industrial-process, and educational use, including equipment and computing devices for measurement, control, laboratory use, and accessories intended for use with the above. Computing devices and assemblies within the scope of information technology equipment (ITE) and complying with applicable ITE EMC standards can be used without additional testing. Where a relevant dedicated EMC standard exists, it shall take precedence over all aspects of this product-family standard. The following equipment is covered in this standard:
a) Electrical measurement and test equipment: This includes equipment that measures, indicates, or records one or more electrical or non-electrical quantities by electrical means, as well as non-measuring equipment such as signal generators, measurement standards, power supplies, and transducers.
b) Electrical control equipment: This includes equipment that controls one or more output quantities to specific values, with each value determined by manual settings, local or remote programming, or one or more input variables. This includes industrial process measurement and control (IPMC) equipment, which consists of devices such as:
- Process controllers and regulators;
- Programmable controllers (PC);
- Power supply units of equipment and systems (centralized or dedicated);
- Analog/digital indicators and recorders;
- Process instrumentation;
- Transducers, positioners, intelligent actuators, etc.
c) Electrical laboratory equipment: This includes equipment that measures, indicates, monitors, or analyzes substances, or is used to prepare materials. This standard is applicable to:
- Equipment for use in industrial locations;
- Equipment for use in laboratories or test and measurement areas with a controlled electromagnetic environment;
- Test and measurement equipment which is portable and powered by battery or from the circuit being measured.
This equipment may also be used in areas other than laboratories.
