This European Standard deals with mechanical rail joints for flat bottom rails 46 kg/m and over.

The scope of this standard is:

— to establish requirements for insulated and non-insulated rail joints, for stressed rail (continuous welded rail, CWR) and unstressed rail (jointed track);

— to define mechanical and electrical requirements for type approval and for acceptance of insulated rail joints which are manufactured in a factory (prefab construction) as well as assembled on-site (site construction).

This standard specifies the minimum requirements. Special applications as for instance tram systems may require different demands in certain paragraphs and should be agreed between customer and supplier.

The scope also excludes expansion joints (it is covered in EN 13232-8), and special joints in switch constructions

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.

This document specifies the minimum ergonomic and structural integrity requirements for steps and handrails used by staff to access the following heavy rail vehicles:

— passenger vehicles;

— vans;

— locomotives;

— power units of rolling stock;

— passenger-rated car carriers.

This document defines the required spaces necessary for shunter handrails and shunter’s stand and gives references for the required spaces necessary for handling of screw couplings with side buffers. For staff access, it defines footsteps, handrails and their dimensions and free spaces. To fulfil the requirements for loads which are applied by the staff, it defines dimensions and requirements for materials or design loads.

This document also defines the general requirements of steps and handrail for access to external equipment, for example windscreens, wipers or external lights.

This document defines the general terms and basic requests for adhesive bonding and sealing work as well as the requirements placed on adhesive users (hereafter called user-companies) and represents the state of the art for organizing adhesive bonding and sealing processes in the railway industry.

This document applies for adhesive bonding and sealing adherends for:

— the development of rail vehicles and its components (pre-production),

— production of rail vehicles and its components (in-production),

— the maintenance incl. repair of rail vehicles and its components (post-production), and

— the quality assurance of production, inspection, maintenance incl. repair of rail vehicles and its components.

This document is valid for every adhesively bonded joint in railway vehicles and its components independent of the material of the adherend. It is also valid for all kinds of adhesives independent of their solidification mechanism, their strength and their deformation properties.

This document is not valid for:

— screw retention by the usage of adhesives, if a pure screw assembly of the same design is sufficient for the purpose,

— hybrid joints, if the expected function is given exclusively by another joining technology e.g. welding, screwing, riveting,

— production of vulcanizates which do not lead to adhesively bonded joints,

— production of plywood,

— production of fibre reinforced plastic composites (FRP-composites),

— production of laminated sheet glass (LSG),

— pure encapsulating of electronic parts, and

— single-sided adhesive decorative films.

This document gives rules for improving the safety of existing escalators and moving walks with the aim of reaching an equivalent level of safety to that of a newly installed escalator and moving walk by the application of today’s state of the art for safety.

NOTE Due to situations such as the existing machine or building designs, it may not be possible in all cases to reach today’s state of the art for safety. Nevertheless the objective is to improve the level of safety wherever possible.

This document includes the improvement of safety of existing escalators and moving walks for:

a) users;

b) maintenance and inspection personnel;

c) persons outside the escalator or moving walk (but in its immediate vicinity);

d) authorized persons.

This document is not applicable to:

a) safety during transport, installation, repairs and dismantling of escalators and moving walks;

b) spiral escalators;

c) accelerating moving walks.

However, this document can usefully be taken as a reference basis.
