CEN/TC 164/WG 13 - Water conditioning equipment inside buildings

This European Standard specifies definitions, principles of construction (but not dimensions) and design, requirements on performance and operation as well as methods for testing the performance of adjustable chemical dosing systems for conditioning water intended for human consumption inside buildings (see [1]) which are permanently connected to the mains supply.
The concentration in the treated water of the active chemical(s) as well as of any other ingredient or minor component (including possible contaminants) should not exceed the parametric values laid down in the existing legislation in the Member States for the water intended for the human consumption, as implemented by the national authorities.

This document specifies definitions, principles of construction, requirements and methods for testing the performance of UV devices for drinking water installations inside buildings which are permanently connected to the mains supply at the point of entry into a building or within the water distribution system inside the building.
UV devices in the sense of this standard are UV bactericidal treatment devices or UV disinfection devices.

This European Standard specifies requirements relating to the construction, performance and methods of testing for active media filters for drinking water installations inside buildings, with a maximum working pressure of at least 1 000 kPa and a maximum working temperature of less than 30 °C. It only concerns units, which are permanently connected to the mains supply at the point of entry or point of use.
This standard applies only to filter systems comprising a housing and filter media tested together.
It includes capsule type units where both the element and its outer housing are disposable.
NOTE   Products intended for use in water supply systems are to comply, when existing, with national regulations and testing arrangements that ensure fitness for contact with drinking water. The Member States relevant regulators and the EC Commission agreed on the principle of a future unique European Acceptance Scheme (EAS) which would provide a common testing and approval arrangement at European level.
If and when the EAS is adopted, European Standards on products will be amended by the addition of an Annex Z/EAS under Mandate M/136 which will contain formal references to the testing, certification and product marking requirements of the EAS. Until the EAS comes into force, the current national regulations remain applicable.

This European Standard specifies definitions, principles of construction (but not dimensions) and design, requirements on performance and operation as well as methods for testing the performance of chemical pre-set dosing systems for conditioning water intended for human consumption inside buildings (see [7]) which are permanently connected to the mains supply

This document specifies requirements relating to the construction, performance and methods of testing for mechanical filters for the removal of suspended matter in drinking water installations inside buildings. It applies to filters with a filtration rating from 1 µm up to less than 80 µm and which are intended for use in systems with a minimum pressure rating of PN 6, connections between DN 15 and DN 100 and service temperature of less than 30 °C.
This document is applicable to back-washable filters, integral filters and those designed for replaceable cartridges. It only concerns units that are permanently connected to the mains supply at point of entry or point of use.
Part 1 of this standard (EN 13443-1) is a separate document and deals with filters with a particle rating between
80 µm and 150 µm.

This European Standard specifies requirements relating to the construction and mode of operation and relevant methods of testing of automatic, salt-regenerated, cation exchange softeners for drinking water installations inside buildings which are permanently connected to the mains supply.
Until EAS comes into force, the current national regulations remain applicable.
NOTE   Products intended for use in water supply systems should comply, when existing, with national regulations and testing arrangements that ensure fitness for contact with drinking water. The Member States relevant regulators and the EC Commission agreed on the principle of a future unique European Acceptance Scheme (EAS) which would provide a common testing and approval arrangement at European level.
If and when the EAS is adopted, European Standards on products will be amended by the addition of an Annex Z/EAS under Mandate M/136 which will contain formal references to the testing, certification and product marking requirements of the EAS.

This European Standard specifies requirements relating to the construction and mode of operation and relevant methods for testing automatic, salt-regenerated, anion exchange nitrate removal devices for drinking water installations inside buildings, which are permanently connected to the mains supply.

Part 1 of this European standard applies to mechanical filters for drinking water installations inside buildings, of nominal size from DN 15 to DN 100, minimum nominal pressure PN10, particle rating of 80 to 150 µm, and minimum design temperature of 30°C. It specifies requirements relating to the construction and mode of operation of filters and describes relevant methods of testing. It only concerns units which are permanently connected to the mains supply at the point of entry into the building.

This European Standard specifies requirements relating to the construction, performance and methods of testing for membrane separation systems with a particle rating below 1 m, namely microfiltration (MF), ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO) for drinking water installations inside buildings, intended to remove from the drinking water marginal concentrations of suspended and colloidal solids, microorganisms, organic molecules and/or to reduce the dissolved solids concentration and applies to systems with a minimum pressure of PN 10, connections between DN 15 and DN 100 and a maximum working temperature of at least 30 °C.
This European Standard applies to membrane separation systems, whose elements may be partly or entirely cleanable or disposable in accordance with the type of system. It only concerns units which are permanently connected to the mains supply at the point-of-entry or the point-of-use.
A membrane separation system may include, together with the separation device pre- and /or post-treatment devices.
For the scope of this European Standard:
-   separation device shall comply with this European Standard, i.e. without pre-and/or post-treatments;
-   where pre-and/or post-treatment devices are incorporated in the system, each of them shall conform to the relevant standard. If this is the case, the complete system shall be considered as conforming as a whole.

This European Standard applies to electrolytic dosing systems for conditioning water intended for human consumption inside buildings and based on dissolution of aluminium anodes (with imposed DC current). It specifies constructional (but not dimensional) and operational requirements. It describes relevant methods for testing performance and safety. It only concerns units which are permanently connected to the mains supply.
