HBES/BACS covers any combination of HBES and/or BACS devices including their separate connected/detachable devices linked together via one or more networks Part of this series applies to HBES/BACS devices and defines the environmental conditions for these devices Scope This European Standard provides the environmental conditions for all devices connected to HBES/BACS This European Standard is applicable (but not limited) to - operator stations and other human system interface devices, - devices for management functions, - control devices, automation stations and application specific controllers, - field devices and their interfaces, - cabling and interconnection of devices, - dedicated devices for engineering and commissioning tools for HBES/BACS The standard defines the general requirements for devices operating in weather protected and nonweather protected locations, ship environments, portable use and also for storage and transport Normative references The following
