IEC 61000-6-2: Immunity Testing of Industrial Equipment

IEC 61000-6-2 is an international EMC test standard for the radiated and conducted immunity of electrical and electronic devices designed for industrial environments. IEC 61000-6-2 immunity requirements pertain to instruments that operate in the 0 Hz to 400 GHz range. Immunity tests covered by IEC 61000-6-2 include transient, continuous, conducted and radiated disturbances as well as electrostatic discharge (ESD) testing. Testing only needs to be performed on industrial equipment at the bandwidths in which requirements exist. IEC 61000-6-2 applies to all the following equipment categories:

1. Devices for which there are no dedicated product/product-family EMC immunity standards.
2. Devices intended to operate in industrial environments.
3. Devices dedicated to operation in a plant involved in installation feeding manufacturing or similar processes.
4. Devices that are battery operated and developed for industrial use.

Industrial locations, discussed often in the standard, are defined by the following qualities:

• Meet CISPR 11 definition of an ISM apparatus—industrial, scientific or medical.
• Frequent switching of inductive or capacitive loads.
• High magnetic fields and currents.
