Geležinkelio taikmenys. Infrastruktūra. Bėgių kelio tiesimo ir techninės priežiūros mašinos. 3 dalis. Bendrieji saugos reikalavimai

This document applies to railbound machines and other vehicles - referred to as machines - working exclusively on the railway (utilizing friction adhesion between the rail and rail wheels) but including machines that in working position are partly supported on the ballast or the formation and used for construction, maintenance and inspection of track, structures, infrastructure and fixed electric traction equipment. This document applies to machines that are intended to operate signalling and control systems. NOTE 1 Other rail mounted railway maintenance and infrastructure inspection machines are dealt with in other European Standards, see Technical Report CEN/TR 17498:2020. This document specifies the significant hazards, hazardous situations and events common to rail bound machines and arising due their use on railways when they are used as intended or under conditions of misuse which are reasonably foreseeable, see Clause 4. This document specifies the common hazards, in normal circumstances, during running, assembly and installation, commissioning, use (including setting, programming, and process changeover), operation, cleaning, fault finding, maintenance and de-commissioning of the machines. Additional safety measures can be required by exceptional circumstances, such as extreme ambient temperatures highly corrosive or contaminating environment; e.g. due to the presence of chemicals, and potentially explosive atmospheres. NOTE 2 This document covers the essential health and safety requirements connected to the use of railbound machines as outlined in the Machinery Directive. This document does not apply to the following: - requirements for quality of the work or performance of the machine; - use of separate equipment temporarily mounted on machines; - operation subject to special rules, e.g. potentially explosive atmospheres; - hazards due to natural causes, e.g. earthquake, lightning, flooding; - working methods; - operation in severe working conditions requiring special measures, e.g. corrosive environments, contaminating environments, strong magnetic fields; - hazards occurring when used to handle suspended loads which may swing freely; - autonomous mobile machines. NOTE 3 Autonomous mobile machines are referred to as ‘autonomous mobile machinery’ in the Machinery Regulations 3.1.1 c).

Geležinkelio taikmenys. Infrastruktūra. Bėgių kelio tiesimo ir techninės priežiūros mašinos. 1 dalis. Važiavimo techniniai reikalavimai

This document defines the specific technical railway requirements for running of machines and other vehicles used for construction, maintenance and inspection of track, structures, track formation and fixed electric traction equipment. Special national conditions applicable to specific member states are shown in Annex B. This document applies to all railbound machines and other vehicles - referred to as machines - running exclusively on the railway (utilizing adhesion between the rail and wheels) and used for construction, maintenance and inspection of track, structures, infrastructure and fixed electric traction equipment. This document applies to machines that are intended to operate signalling and control systems. NOTE Other rail mounted railway maintenance and infrastructure inspection machines are dealt with in other European Standards, see Technical Report CEN/TR 17498:2020. This document is written for 1 435 mm nominal track gauge; special requirements can apply for running on infrastructures with narrow gauge or broad gauge lines, urban railways, railways utilizing other than adhesion between the rail and wheels and road-rail machines which are not included in this standard. This document covers the railway specific requirements for movements of the machine as a train and movements to reach work sites. This document applies to equipment and systems which are operational on machines in running mode.

Geležinkelio taikmenys. Aerodinamika. 4 dalis. Aerodinamikos atvirame geležinkelio kelyje reikalavimai ir vertinimo procedūros

This document establishes requirements, test procedures, assessment methods and acceptance criteria for operating rolling stock in open track. For pressure variations and slipstream effects beside the track, requirements and assessment methods are provided. For running resistance, assessment methods are addressed in this document. Load cases on infrastructure components due to train-induced pressure variations and slipstream effects are addressed in this document. For ballasted track test set-ups for ballast projection assessment are proposed. The requirements only apply to rolling stock of the heavy rail system with maximum train speeds above 160 km/h and not to other rail systems. The document is applicable to all rolling stock and infrastructure in open air with nominal track gauges of 1 435 mm to 1 668 mm inclusive.

Plastikai. Termoplastinių medžiagų bandinių liejimas slegiant. 5 dalis. Standartinių bandinių paruošimas anizotropijai tirti (ISO/DIS 294-5:2024)

ISO 294-5:2017 specifies a mould (designated the type F ISO mould) for the injection moulding of plates with a preferred size of 80 mm × 120 mm and a minimum size of 80 mm × ≥90 mm and with a preferred thickness of 2 mm for single-point and multi-point data acquisition. It has been found to provide the maximum anisotropic properties, with only a slight sensitivity to the rate of injection. Whenever possible, a two cavity mould is intended to be used. For the design of plastic parts, this will provide upper and lower bounds for the tensile properties. Matching the plate thickness to a given part thickness is not a suitable criterion because of the effect of mould filling rate and part geometry on anisotropy. Investigation of the anisotropy of materials is a special procedure intended to provide guidance in the design of mouldings for end-use applications and is not intended as a quality control tool. In the injection moulding of thermoplastic materials, the flow of molten polymer can influence the orientation of fillers such as fibreglass or the orientation of polymer chains, resulting in anisotropic behaviour. For the purposes of ISO 294-5:2017, the flow direction is defined as the direction from the gate to the far end of the mould cavity and the cross direction as the direction perpendicular to the flow direction. The type F mould is not intended to replace the type D mould used to determine the moulding shrinkage of thermoplastics.

This document specifies safety and hygiene requirements for the design and manufacture of rotary rack ovens which can be used with one or more mobile racks. These ovens are intended for professional use in the food industry and workshops (bakeries, pastry-making, etc.) for the batch baking of foodstuffs containing flour, water and other ingredients and/or additives. This document applies to ovens used only for food products except for those containing volatile flammable ingredients (volatile organic compound, e.g. alcohol, oil, …). This document applies to ovens where the steam is generated by an evaporation process of drinking water on hot surfaces. The following machines are excluded: - experimental and testing machines under development by the manufacturer; - machines for non-professional uses. NOTE Due to the fact that rotary rack ovens are intended for professional uses, EN 60335-1 and EN 60335-2-42 are not applicable. This document covers the technical safety requirements for the transport, installation, operation, cleaning and maintenance of these machines (see EN ISO 12100:2010, Clause 6). This document deals with all significant hazards, hazardous situations and events relevant to rotary rack ovens when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see informative Annex C). The following hazards are not covered by this document: - hazards from the use of gaseous fuel by gas appliances; - hazards arising from electromagnetic compatibility issues; - hazards from the use of trays made of or coated by silicone; - hazards due to dismantling, disabling and scrapping. This document does not deal with noise emitted by the machine. This document is not applicable to rotary rack ovens which were manufactured before the date of its publication as an EN.
