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

manufacturer's installation and operations literature which accompanies the product; - the product information contained in the manufacturer's catalogue and other product marketing material-information; - the description, definitions, product literature and usage as presented in electronic format on the manufacturer's (or supplier's) website on the World Wide Web/Internet 3.2 weather protected locations: controlled conditions locations that are enclosed, and where direct weather influences are totally excluded In addition, temperature is controlled by heating or cooling to maintain the required conditions, especially where these are very different from those of the open-air climate Humidity is not controlled Vibration and shock are insignificant These locations may be in rural and some urban areas with low industrial activities and moderate traffic There is no particular risk of biological attack due to mould growth, animals, etc EXAMPLES: - normal living or working areas, for example living rooms, and rooms for general use such as theatres, restaurants, offices, shops, workshops for electronic assembly and products; BS BS EN EN 50491-2:2010+A1:2015
