This document classifies floor gullies for use inside buildings, gives guidance for places of installation and specifies requirements for the construction, design, performance and marking of factory made gullies for buildings, irrespective of the material, for use in drainage systems requiring a trap with combined mechanical closure and water seal (referred to as floor gullies). Note: Floor gullies with combined mechanical closure and water seal are not covered by Part 1, Part 6, Part 7. These products are intended to be installed where: - the building does not exceed a ground-floor and three floors above.

This document classifies floor gullies for use inside buildings, gives guidance for places of installation and specifies requirements for the construction, design, performance and marking of factory made gullies for buildings, irrespective of the material, for use in drainage systems requiring a trap with a depth of water seal of less than 50 mm (referred to as floor gullies). Note: Floor gullies with a depth water seal of less than 50 mm are not covered by Part 1, Part 7, Part 8. These products are intended to be installed only where: - space limitation will not accommodate a gully with a 50 mm water seal; - the building does not exceed a ground-floor and three floors above; - at least two sanitary appliances are installed in addition to the gully but with only one toilet on the same branch (connection pipe); - or secondary or branch ventilation is installed according to clauses 4.3.2 or 4.3.4 of EN 12056-2.

This document specifies the field of application, the dimensional, the physico-chemical, the design, the hydraulic, the mechanical, and the acoustic characteristics of controllable backflow preventers with reduced pressure zone Family B Type A. This document covers controllable backflow preventers of Family B Type A, with reduced pressure zones, intended to prevent pollution of potable water by backflow, caused by backsiphonage or by backpressure. It is applicable to controllable backflow preventers in denominations DN 6 up to DN 250. It covers controllable backflow preventers of PN 10 that are capable of working without modification or adjustment: - at any pressure, up to 1 MPa (10 bar); - with any pressure variation, up to 1 MPa (10 bar); - in permanent duty at a limited temperature of 65 °C and for maximum 1 h at 90 °C. It specifies also the test methods and requirements for verifying their characteristics, the marking and the presentation at delivery.

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 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 document specifies the test gases, test pressures and categories of appliances relative to the use of gaseous fuels of the first, second and third families. It serves as a reference document in the specific standards for appliances that fall within the scope of the Council Directive on the approximation of the laws of Member States concerning gas appliances 2009/142/EC. The standard makes recommendations for the use of the gases and pressures to be applied for the tests. The full procedure will be given in the corresponding appliance standards. NOTE The test gases and the test pressures specified in this standard are in principle intended to be used with all the appliances in order to establish conformity with the corresponding standards. However, the use of some test gases and test pressures may not be appropriate in the following cases: - appliances with nominal heat input greater than 300 kW; - appliances constructed on site; - appliances in which the final design is influenced by the user; - appliances constructed for use with high supply pressures (notably direct use of the saturated vapour pressure). In these cases, the specific appliance standards may specify other test conditions in order to establish compliance with their requirements.
