This document is applicable to efficient particulate air filters (EPA), high efficiency particulate air filters (HEPA) and ultra-low penetration air filters (ULPA) used in the field of ventilation and air conditioning and for technical processes, e.g. for applications in clean room technology or pharmaceutical industry. This document establishes a procedure for the determination of the efficiency on the basis of a particle counting method using a liquid (or alternatively a solid) test aerosol and allows a standardized classification of these filters in terms of their efficiency, both local and integral efficiency. This document is based on particle counting methods which actually cover most needs of different applications.

This document specifies definitions, principles of construction, requirements and methods for testing the performance of UV devices (240 nm to 290 nm nominal) for potable water installations according to EN 806-2 which are permanently connected to the building’s supply. Devices described by this document can be installed at the point of entry (POE), within the water distribution system inside the building or at the point of use (POU). Additionally, the devices described in this document can be used in mobile or temporary potable water installations, where the system is not permanently connected to a water supply. UV devices in the sense of this document are UV bactericidal treatment devices or UV disinfection devices for one of three specified water qualities, determined by the observed UV transmittance. Devices can be standalone, integrated into a larger appliance or part of multi-staged treatment process. The document relates solely to the performance of the UV reactor.

This document is applicable to metallic stop valves for use with water intended for human consumption. This document specifies: — requirements for the design of stop valves; — mechanical, hydraulic and acoustic requirements; — test methods; — marking requirements. This document is applicable to metallic stop valves, dimensions DN 10 to DN 100, for potable water installation in buildings for PN10 or PN16 and a distribution temperature of 65 °C. This document is applicable to stop valves in combination with accessories in the same body.

This document specifies dimensions, materials and performance requirements, including methods of test, for hydraulic safety groups, of nominal sizes from DN 15 to DN 25, having working pressures from 0,1 MPa (1 bar) to 1,0 MPa (10 bar). Hydraulic safety groups are intended for fitting to the potable water supply of storage water heaters, having a maximum storage temperature of 95 °C. Hydraulic safety groups limit the pressure in hot water heaters, prevent the backflow of water into the main circuit and prevent the discharged water to get into contact with the water in the water heater. Hydraulic safety groups do not control the temperature. They ensure the hydraulic safety of water heaters if the mechanical resistance of the water heater remains at least equal to the rating pressure. NOTE The use of the device specified in this document does not override the need to use controls (e.g. thermostats and cut-outs) which act directly on the power sources of water heaters (for more information see Annex A).

This document specifies, dimensions, materials and performance requirements (including methods of test) for expansion groups, of nominal sizes from DN 15 to DN 25, having working pressures from 0,1 MPa (1 bar) to 1,0 MPa (10 bar). Expansion groups are fitted to the cold potable water supply only for expansion purposes, e.g. of storage water heaters, having a maximum distribution temperature of 95 °C. Expansion groups limit pressure in the water heater to which they are fitted, that is produced by thermal expansion of the water, prevent the backflow of water into the supply pipe and prevent the discharged water to get into contact with the water in the water heater. Expansion groups do not control temperature and alone do not constitute the protection required for storage water heaters. NOTE The use of the device specified in this document does not override the need to use controls (e.g. thermostats and thermal cut-outs) which act directly on the power sources of water heaters (for more information see Annex A).

This document specifies dimensions, materials and performance requirements, including methods of test, for pressure safety valves, of nominal sizes from DN 15 to DN 40, having working pressures from 0,1 MPa (1 bar) to 1,0 MPa (10 bar). Pressure safety valves are intended for fitting to the potable water supply of storage water heaters, having a maximum storage temperature of 95 °C. Pressure safety valves limit the pressure in hot water heaters. Pressure safety valves do not control the temperature and alone do not constitute the protection required for storage water heaters. They are not intended to act as expansion valves under normal conditions. NOTE The use of the device specified in this document does not override the need to use controls (e.g. thermostats and cut-outs) which act directly on the power sources of water heaters (for more information see Annex A).

This document specifies dimensions, materials and performance requirements (including methods of test) for expansion valves, of nominal sizes from DN 15 to DN 50, having working pressures ) from 0,1 MPa (1 bar) to 1,0 MPa (10 bar). Expansion valves are intended for fitting to the cold potable water supply of storage water heaters, having a maximum distribution temperature of 95 °C, for all energy sources. Expansion valves do not control the temperature and alone do not constitute the protection required for storage water heaters. Expansion valves limit pressure, in the water heaters to what they are fitted, that is produced by thermal expansion of the water. NOTE The use of the device specified in this document does not override the need to use controls (e.g. thermostats and cut-outs) which act directly on the power sources of water heaters (for more information see Annex A).

In these cases, this document can be used as a basis with further measures as required from risk assessment; - the provision of evacuation aids to assist when the evacuation lift is unavailable; - lifts with partially enclosed wells; - lifts installed in new or existing buildings, which are not included in fire resisting building structure. 1.3 This document does not define the use of other than the highest deck of a multi deck lift for firefighting operations. 1.4 The significant hazards covered by this document are listed in Annex H. 1.5 The following significant hazards are out of the scope of this document: - fire or smoke in the firefighters lift well, safe areas, machinery spaces or car; - ingress of water to the lift well during firefighting operations; - insufficient or incorrectly located firefighters lifts; - insufficient firefighters lift capacity; - inability of users to understand the use of the lift in firefighting operations; - entrapment in waiting area (safe area) due to absence of lift service or adjacent stairs; - structural collapse or failure of building services (including public supply network, lighting, ventilation) before the firefighting using lifts has been completed; - presence of harmful gases, potentially explosive atmosphere, extreme climate conditions, transport of dangerous goods; - unavailability of the firefighters lift. This document is not applicable to firefighters lifts manufactured before the date of its publication.

This document specifies a method for determining the fire resistance of vertical and horizontal ventilation ducts including ancillary items such as access panels, attenuators, compensators and control dampers, which are integral part of the tested ducts. The test examines the behaviour of ducts exposed to fire from the outside (duct A) and fire inside the duct (duct B). This document is used in conjunction with EN 1363-1. Annex A provides general guidance and gives background information. This document is not applicable to: a) ducts whose fire resistance depends on the fire resistance performance of a ceiling or wall (where ducts are located in cavities enclosed by fire-resistant shafts or ceilings); b) ducts containing fire dampers at points where they pass through fire separations; c) one, two or three sided ducts; d) fixing of suspension devices (e.g. anchors) to floors or walls.
