This document specifies a method for the determination of the water vapour transmission properties of waterproofing sheets. It is applicable to factory made bitumen, plastic and rubber sheets for roof waterproofing, damp proof sheets, damp proof courses, underlays and vapour control layers.

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 specifies materials and the general aspects of polyethylene (PE) pressure piping systems (mains and service pipes) for buried or above ground applications, intended for the conveyance of:

water intended for human consumption,

raw water prior to treatment,

drains and sewers under pressure,

vacuum sewer systems,

water for irrigation,

water for other purposes, with the exception of industrial applications.

The intended use includes sea outfalls, laid in water and pipes suspended below bridges.

NOTE 1:

Attention is drawn to Clause 6 of this document for PE components for the conveyance of water intended for human consumption and raw water prior to treatment. Components manufactured for water for other purposes, drains and sewers, and vacuum sewer systems are possibly not suitable for water supply for human consumption.

PE pipe systems for industrial applications and irrigation with limited pressure exposure are not covered by this document.

NOTE 2:

Industrial application is covered by ISO 15494, irrigation with limited pressure exposure is covered by ISO 8779 (Ed3).

This document also specifies the test parameters for the test methods referred to in this document.

In conjunction with ISO/DIS 4427-2, ISO/DIS 4427-3 and ISO/DIS 4427-5, this document is applicable to PE pipes and fittings, their joints and to joints with components made of PE and other materials, intended to be used under the following conditions:

a) a maximum allowable operating pressure (3.3.2) (PFA) up to and including 25 bar;

b) an operating temperature of 20 °C as the reference design temperature (3.3.3).

For applications operating at constant temperatures greater than 20 °C and up to and including 50 °C, see Annex A.

The ISO 4427 series covers a range of maximum allowable operating pressures and gives requirements concerning colours.

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 guidance or regulations and installation practices or codes.

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 is not applicable to regulating or servicing valves, designed specially to isolate sanitary tapware or other sanitary appliances.

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).

This document specifies application, general construction, performance and material requirements for frost resistant taps for outdoor use (FRT), PN 10. This document is applicable to potable water installations with a static pressure of maximum 1,0 MPa (10 bar) and a distribution temperature of maximum 25 °C (PWC). NOTE See Annex A for a general overview of this document’s organization and test sequence.
