This part of IEC 61326 covers all equipment within the scope of IEC 61326-1, but is limited to
systems and equipment for industrial applications within a specified electromagnetic
environment and intended to perform safety functions as defined in IEC 61508 with SIL 1-3.
The electromagnetic environments encompassed by this product family standard are
industrial, both indoor and outdoor, and based on the requirements of the process industry,
specifically chemical/petrochemical/pharmaceutical manufacturing plants using the mitigation
measures given in Annex C. The difference between the electromagnetic environment
covered by this standard compared to the general industrial environment (see IEC 61326-3-1)
is due to the mitigation measures employed against electromagnetic phenomena leading to a
specified electromagnetic environment with test values that have been proven in practice.
The environment of industrial application with a specified electromagnetic environment
typically includes the following characteristics:
industrial area with limited access;
limited use of mobile transmitters;
dedicated cables for power supply and control, signal or communication lines;
separation between power supply and control, signal or communication cables;
factory building mostly consisting of metal construction;
overvoltage/lightning protection by appropriate measures (for example, metal construction of the building or use of protection devices);
pipe heating systems driven by a.c. main power;
no high-voltage substation close to sensitive areas;
presence of CISPR 11 Group 2 ISM equipment using ISM frequencies only with low power;
competent staff;
periodical maintenance of equipment and systems;
mounting and installation guidelines for equipment and systems.
Equipment and systems considered as proven-in-use according to IEC 61508 or prior use
according to IEC 61511 are excluded from the scope of IEC 61326-3-2.
Fire alarm systems and security alarm systems intended for protection of buildings are
excluded from the scope of IEC 61326-3-2.
