适用范围：The scope of IEC 61326-1 applies to this part of IEC 61326 but is limited to systems andequipment for industrial applications within a specified electromagnetic environment andintended to perform safety functions as defined in IEC 61508 with SIL 1-3.The electromagnetic environments encompassed by this product family standard areindustrial, both indoor and outdoor, as they can be found in industrial applications with anelectromagnetic environment having specified characteristics (for example, process industry).The difference between the electromagnetic environment covered by this standard comparedto the general industrial environment (see IEC 61326-3-1) is due to the mitigation measuresemployed against electromagnetic phenomena leading to a specified electromagneticenvironment.The environment of industrial application with a specified electromagnetic environmenttypically includes the following characteristics:– industrial area with limited access;– limited use of mobile transmitter;– 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 constructionof the building or use of protection devices);– pipe heating systems driven by a.c. main power may be present;– no high-voltage substation close to sensitive areas;– presence of CISPR 11 Group 2 ISM equipment using ISM frequencies only with lowpower;– competent staff;– periodical maintenance of equipment and systems;– mounting and installation guidelines for equipment and systems.A more detailed description of the above-mentioned typical characteristics is given inAnnex B.Equipment and systems considered as “proven-in-use” according to IEC 61508 or IEC 61511are excluded from the scope of IEC 61326-3-2.Fire alarm systems and security alarm systems intended for protection of buildings areexcluded from the scope of IEC 61326-3-2.
