Geležinkelio taikmenys. Aplinkos poveikis įrenginiams

This document intends to define environmental conditions within Europe. This document does not specify the test requirements for equipment. The scope of this document covers the definitions and ranges of the following parameters: altitude, temperature, pressure, humidity, air movement, rain, snow, hail, ice, lightning, electromagnetic compatibility, solar radiation, pollution, vibrations and shocks, environmental conditions in tunnels. The scope of this document is to define environmental conditions in railway environment in order to cover the design and the use/service of the following: — equipment for rolling stock and on-board equipment (mechanical, electromechanical, electrical, electronic); — fixed electrical installations for traction power supply and equipment essential to operate a railway; — equipment and any portable equipment for signalling and telecommunications systems (including test, measure, monitoring equipment, etc.). The defined environmental conditions, including the values herein specified, are considered as normal and do not concern extreme conditions or natural disasters (e.g earthquake, nuclear radiation). This document does not apply to cranes, mining vehicles, cable cars, escalators, lifts, fire protection, lighting in tunnels and on platforms, ticket machines, ventilation systems, installations in underground mines, suspended cable cars and funicular railways. The effects of vandalism on the equipment are not considered in this document. Microclimates surrounding components and passenger effects on the equipment and equipment effects on the passengers are not considered in this document.

Geležinkelio taikmenys. Infrastruktūra. Bėgių atnaujinimas, taikant elektrinį lankinį suvirinimą

This document specifies restoration by electric arc welding and is limited to the head of the rails only. This document describes the approval systems for consumables and procedures used in manual metal arc and flux cored metal deposit rail repair welding. This document includes the quality-related tasks and responsibilities of personnel involved in the electric arc repair welding of rails. This document applies to plain rail and switches and crossings manufactured from new Vignole railway rails R200, R220, R260, R260Mn, and R350HT grades rails of 27 kg/m and above as contained in EN 13674-1, EN 13674-2 and EN 13674-4. The permitted welding processes are limited to Electric Arc (EA) in accordance with EN ISO 4063 and are by description Process No 111: SMAW (Shielded Metal Arc Welding) and Process No 114: FCAW (Flux Cored Arc Welding). This document can be applied in situ, at line side or at out of track locations. The flash welded leg ends of austenitic manganese steel crossings are included in this document, except when located within 500 mm of manganese crossings. Where repairs are required within 500 mm, refer to EN 16725.

Geležinkelio taikmenys. Bėgių kelias. Gelžbetoniniai pabėgiai su padėklais

This European Standard is applicable to concrete sleepers or bearers with Under Sleeper Pads (USP) physically bonded to concrete used in ballast track and define the test procedures and their evaluation criteria. This standard provides particular information in the following areas: - test methods, test arrangements and evaluation criteria of Under Sleeper Pads; - test methods, test arrangements and evaluation criteria of concrete sleepers and bearers with Under Sleeper Pads; - data supplied by the purchaser and by the supplier; - definition of general process of design approval tests; - definition of routine tests. This standard defines the specific test procedures for design approval tests, routine tests and tests concerning the determination of relevant properties of Under Sleeper Pad with or without concrete sleepers and bearers: - fatigue tests; - tests of capability for stacked stocking of concrete sleepers or bearers fitted with USP; - pull-out test; - severe environmental condition test. This standard also sets out procedures for testing fitness for purpose and provides information on quality monitoring as part of quality assurance procedures. This standard does not, however, contain requirements pertaining to the properties of Under Sleeper Pads. It is the responsibility of the purchaser to define these requirements

Geležinkelio taikmenys. Geležinkelio transporto priemonių ženklinimas. 2 dalis. Išorinis keleivinių vagonų, savaeigių riedmenų, lokomotyvų ir bėgių kelio tiesimo bei techninės priežiūros mašinų ženklinimas

This document specifies the external markings on heavy rail vehicles including heavy rail railbound construction and maintenance machines but except freight wagons relating to their technical and operational characteristics. This document specifies the characteristics of these markings, the requirements pertaining to their presentation, their shape and position on a rail vehicle and their meaning. Some markings are accompanied with note(s) where appropriate. Service markings relating to passenger information are not addressed by this document. The document is applicable to all heavy rail coaches, motive power units, locomotives and railbound construction and maintenance machines operating within the European Union, the European Free Trade Association Member States and States which are member of OTIF (Intergovernmental Organisation for International Carriage by Rail).

Geležinkelio taikmenys. Ryšių, signalizavimo ir duomenų apdorojimo sistemos. Su sauga susiję ryšiai, naudojami perdavimo sistemose

This document is applicable to safety-related electronic systems using for digital communication purposes a transmission system which was not necessarily designed for safety-related applications. For transmission systems where the risk of unauthorized access is not tolerable, the document defines the interface to the applicable cybersecurity standards. Both safety-related equipment and non-safety-related equipment can be connected to the transmission system. This document gives the specific requirements needed to achieve safety-related communication between safety-related equipment connected to the transmission system, while the general system requirements including allocation of safety requirements and content of the safety case are defined in EN 50129. This document is not applicable to existing systems, which had already been accepted prior to the release of this document. However, so far as reasonably practicable, it is applicable to modifications and extensions to existing systems, subsystems and equipment. This document does not specify – the transmission system, – equipment connected to the transmission system, – solutions (e.g. for interoperability), – which kind of data are safety-related and which are not. A safety-related equipment connected through an open transmission system can be subjected to many different IT security threats, against which an overall program is defined, encompassing management, technical and operational aspects.
