This European Standard specifies requirements for the design@ construction and operation of platform barrier systems positioned at the edge of a station platform immediately adjacent to rail or other guided vehicles in stations and boarding points for passenger services and includes: ?? requirements for the fixed structure and fixed parts along the platform; ?? physical requirements for the movable doors and gates normally used by passengers; ?? requirements for emergency doors; ?? requirements for driver access doors; ?? requirements for platform extremity doors; ?? requirements for management of safety risks that are particular to barrier systems. This European Standard also gives requirements for the integration of barriers with the overall rail system including: ?? synchronization of vehicle and platform barrier doors or gates; ?? audible and visible alerts; ?? integrity of control systems; ?? testing of the barrier installation; ?? operational performance; ?? requirements relating to other interfacing sub-systems@ notably signalling and vehicles. For barrier systems set back from the platform edge@ which are used to control access to trains or for crowd management@ relevant sections of the document can be used as guidance. This European Standard applies to all actors involved in the implementation and system integration of a platform barrier system@ including owners@ designers@ installers and operators. This European Standard does not cover barrier systems using bars@ ropes@ etc. or which operate in a vertical direction. Nevertheless@ compliance with relevant clauses from this document can be used in developing safety justifications for these alternative types of barrier system. This European Standard applies to light rail services@ e.g. metro and tramway systems and heavy rail services as requested by a project specification. It applies to small systems@ working in conjunction with a single vehicle@ or with larger systems working with a complete train. This European Standard applies to platform barrier systems used at sub-surface stations@ enclosed surface stations (e.g. those enclosed for the purposes of providing an air-conditioned environment for waiting passengers)@ and those fully in the open-air. This European Standard does not cover normative requirements relating to fire performance or fire requirements arising from use of platform barrier systems as fire barriers.
