This document specifies the requirements for solid wall pipes with smooth internal and external surfaces, extruded from the same formulation throughout the wall, fittings and the system of acrylonitrile-butadiene-styrene (ABS) and acrylonitrile-styrene-acrylester (ASA) piping systems intended for soil and waste discharge applications (low and high temperature):- inside buildings (application area code "B");- for both inside buildings and buried in ground within the building structure (application area code "BD").NOTE 1 The intended use is reflected in the marking of products by "B" or "BD".NOTE 2 Application "B" covers uses above ground inside buildings, or outside buildings fixed onto the wall.NOTE 3 Pipes and fittings of the pipe series S 25 are intended to be used for application area "B" only.NOTE 4 For use buried in ground within the building structure are intended only those components (marked with "BD") with nominal outside diameters equal to or greater than 75 mm.NOTE 5 EN 476 [1] specifies the general requirements for components used in discharge pipes, drains and sewers for gravity systems. Pipes and fittings conforming to this standard fully meet these requirements.This document is also applicable to ABS and ASA pipes, fittings and the system intended for the following purposes:- ventilating part of the pipework in association with discharge applications;- rainwater pipework within the building structure.It also specifies the test parameters for the test method that are referred to.This document covers a range of nominal sizes, a range of pipes and fittings series and gives recommendations concerning colours.NOTE 6 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes.NOTE 7 Pipes, fittings and other components conforming to any of the plastics product standards listed in Annex A can be used with pipes and fittings conforming to this document, provided they conform to the requirements for joint dimensions given in Clause 7 and to the requirements of Table 21.

This document provides a scheme for the assessment of conformity of PE products and assemblies for the rehabilitation of existing pipelines, in accordance with the applicable parts of ISO 11296, ISO 11297, ISO 11298, ISO 11299 and ISO 21225, and intended to be included in the manufacturer's quality plan as part of the quality management system and for the establishment of certification procedures.NOTE In order to help the reader, summary tables of overall scheme requirements are provided in Annex E.

This document specifies the requirements for solid wall pipes with smooth internal and external surfaces, extruded from the same formulation throughout the wall, fittings and the system of chlorinated poly(vinyl chloride) (PVC-C) piping systems intended for soil and waste discharge (low and high temperature) :- inside buildings (application area code "B");- for both inside buildings and buried in ground within the building structure (application area code "BD").NOTE 1 The intended use is reflected in the marking of products by "B" or "BD".NOTE 2 Application "B" covers uses above ground inside buildings, or outside buildings fixed onto the wall.NOTE 3 Pipes and fittings of the pipe series S 25 are intended to be used for application area "B" only.NOTE 4 For use buried in ground within the building structure are intended only those components (marked with "BD") with nominal outside diameters equal to or greater than 75 mm.NOTE 5 EN 476 [1] specifies the general requirements for components used in discharge pipes, drains and sewers for gravity systems. Pipes and fittings conforming to this standard fully meet these requirements.This document is applicable to PVC-C pipes and fittings, their joints and to joints with components of other plastics and non-plastics materials intended to be used for the following purposes:- ventilating part of the pipework in association with discharge applications;- rainwater pipework within the building structure.It also specifies the test parameters for the test methods that are referred to.This document covers a range of nominal sizes, a range of pipe series and gives recommendations concerning colours.NOTE 6 It is the responsibility of the purchaser or specifier to make the appropriate selection from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices codes.NOTE 7 Pipes, fitting and other components conforming to any of the plastics product standards listed Annex A can be used with pipes and fittings conforming to this document, provided they conform to the requirements for joint dimensions given in Clause 7 and to the requirements of Table 21.

This European Standard is applicable to the lines with standard track gauge (1435°mm) and wider track gauges of the heavy rail system and the vehicles that are operated on these lines, except portable trolleys as defined by EN 13977 and maintenance vehicles (e.g. rail mounted plant, cranes) in their working or travelling modes (see EN 14033-2).This European Standard describes methods of classification of existing and new lines of the heavy rail system and the categorisation of rail vehicles.This European Standard gives guidance to a reliable and established management of the interface between rail vehicles and the heavy rail network and does not impose any requirements on either vehicles or infrastructure.The application of this European standard enables to ensure the static route compatibility between a rail vehicle and the heavy rail network with respect to the vertical load carrying capacity.It contains requirements relevant to:- classification of the vertical load carrying capacity of lines of the heavy rail network;- allocation of rail vehicles to line categories (categorisation);- determination of payload limits of freight wagons.Out of the scope of this European standard are- assessments of compatibility based on the parameter axle load alone;- compatibility checks for cases where an additional dynamic analysis is required (for example according to EN 1991-2:2003, 6.4.4);- requirements relating to the maximum total mass or maximum length of a train;- the system used in Great Britain, where all lines and vehicles are classified in accordance with the RA (Route Availability) System. A guide to the equivalent categories in accordance with this European Standard is given in Annex M;- the publication of line categories.The requirements of this European Standard do not replace any regulations related to running behaviour of vehicles described by the assessment quantities for running safety, track loading and ride characteristics (see EN 14363).

This document specifies the minimum requirements for the protection of helium cryostats against excessive pressure, including the specific risks associated with cryostats for superconducting magnets and cryostats for superconducting radio-frequency cavities, coldboxes of helium refrigerators and liquefiers as well as helium distribution systems including valve boxes. It includes risk assessment, protection concepts, dimensioning of pressure relief devices, types of pressure relief devices, substance release and operation of helium cryostats.In order to fulfil the aim of this document, the characteristics of pressure relief devices are taken into account.

This document specifies the properties of piping system components made from glass-reinforced thermosetting plastics (GRP) based on unsaturated polyester resin (UP). It is suited for all types of water supply, drainage and sewerage with or without pressure. Types of water supply include, but are not limited to, raw water, irrigation, cooling water, potable water, salt water, sea water, penstocks in power plants, processing plants and other water-based applications. This document is applicable to GRP UP piping systems, with flexible or rigid joints with or without end thrust load-bearing capability, primarily intended for use in direct buried installations.
