Sectional Specification: Electromechanical all-or-nothing relays (including relays for severe environmental conditions)
This sectional specification applies to electro-mechanical all-or-nothing telays of assessed quality. It selects from the generic specification CECC 16 000 the appropriate methods of the tests to be used in detail specifications derived from this specification, and contains basic test schedules to be used in the preparation of such specifications. Detailed test schedules are contained in the blank detailspecifications supplementary to this specification.

Railway applications - Fixed installations - D.C. switchgear - Part 5: Surge arresters and low-voltage limiters for specific use in d.c. systems
Clauses 1, 2, 3 and 4 of this European Standard cover particular requirements for surge arresters (following named arresters) for specific use in fixed installations of d.c. traction systems. These are surge arresters consisting of one or more non-linear resistors which may be in series with single or multiple spark gaps

Railway applications - Testing for the acceptance of running characteristics of railway vehicles - Freight wagons - Testing of running safety under longitudinal compressive forces
This European Standard defines the acceptance process to be followed by vehicles that are operated in trains capable of generating high longitudinal forces and that are susceptible, as a result of their design, to derailment as a result of being subjected to these forces. This European Standard applies to the following types of freight wagons equipped with standard ends as defined in this EN: - single wagons; - permanently coupled units with side buffers and screw couplers between the vehicles; - permanently coupled units with diagonal buffers with screw couplers between the vehicles; - articulated units with three 2-axle bogies; - low-floor wagons with eight or more axles (e.g. rolling road wagon 1)). The following vehicles are not currently in the scope of this European Standard: - wagons which are not subjected to extensive Longitudinal compressive forces due to their operational environment (as train composition, braking regime, track layout); - wagons with automatic couplers 2); wagons with 3-axle bogies 3); - permanently coupled units with a bar coupler between the vehicles 4); - articulated wagons with more than three 2-axle bogies.

Railway Applications - Fixed Installations - D.C. surge arresters and voltage limiting devices - Part 2: Voltage limiting devices
This European Standard applies to Voltage Limiting Devices (VLDs) to be applied in d.c. traction systems in order to comply with protective provisions against electric shock from d.c., and mixed a.c. - d.c. voltages, in accordance with EN 50122, taking into account stray current provisions. VLDs operate in a way as to connect the track return circuit of d.c. railway systems to earthing system or conductive parts within the overhead contact line zone or current collector zone in order to: 1) prevent impermissible touch voltages caused by train traffic or short circuits; and/or 2) prevent impermissible touch voltages by reducing the fault circuit impedance and thus causing tripping of the circuit breaker by overcurrent.

Electronic railway equipment - Train backbone - Part 2-5: Ethernet Train Backbone
This part of IEC 61375 series of International Standards defines Ethernet Train Backbone (ETB) requirements to fulfil open train data communication system based on Ethernet technology. Respect of this standard ensure interoperability between local consist subnets whatever consist network technology (see IEC 61375-1 for more details). All consist network definitions shall take in account this current part to preserve interoperability. This standard may be additionally applicable to closed trains and multiple unit trains when so agreed between purchaser and supplier.
