1 Scope
This European Standard specifies requirements for and gives recommendations on the design, installation,
alteration, testing, maintenance and operation of potable water installations within buildings and, for certain
purposes, pipework outside buildings but within the premises (see Figure 1).
It covers the system of pipes, fittings and connected appliances installed for supplying potable water.
If there is a private drinking water supply within the property boundary, the scope of this standard also covers the
pipe system from the point of entry from that private water supply.
The sphere of application ends at the downstream end of the potable water installation at which point must be an
air gap, (e. g. at a kitchen tap) or a protection device, (e. g. at a hose union tap).
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text and the publications are listed hereafter. For
dated references, subsequent amendments to or revisions of any of these publications apply to this European
Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the
publication referred to applies.

3 Objectives
The main objectives are to ensure that:
çÅ‚ the deterioration in water quality within the installation is avoided;
çÅ‚ the required flow of water and pressure is available at the draw-off points and at the connection points of
appliances (e. g. water heaters, washing machines);
çÅ‚ the potable water meets the standards for physical, chemical and microbiological quality at the draw-off points;
çÅ‚ all parts of the installation do not cause danger to health and do not damage property within calculated
lifetimes;
çÅ‚ the maintenance of the installation meets the functional requirements at all times during its lifetime;
çÅ‚ sound levels are kept to a practicable minimum;
çÅ‚ contamination of the public water supply, undue consumption, leakage and misuse is avoided.
4 Competence and duties for design, construction and operation
4.1 Designer
The design shall be carried out by competent persons, e. g. persons with relevant experience, qualifications1) ,
knowledge of regulations and safety requirements.
4.2 Installer
The work for construction, alteration and maintenance shall be carried out by competent installers in accordance
with qualification required by national or local regulations.
4.3 Water supplier
The data necessary for design and construction (e. g. supply pressure, the supply flow rates and the water quality
analysis at the point of delivery) shall be determined before commencement of work: the information should be
made available by the water supplier (or the operator of a private or separate water supply).
4.4 Operator
The owner/occupier is responsible for ensuring the safe operation and maintenance of the potable water
installation and should be provided with the necessary information.
5 Terms and definitions
For the purposes of this European Standard, the following terms and definitions apply.
5.1
potable water
for the purpose of this specification, potable water shall be suitable for human consumption and conform with the
