Page 4 EN 806-1 :2000 1 Scope This European Standard specifies requirements for and gives rec
23、ommendations 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 inst
24、alled 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 instal
25、lation 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 appropriat
26、e places in the text and the publications are listed hereafter.

32、 Objectives The main objectives are to ensure that: - the deterioration in water quality within the installation is avoided; - 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); - the potable
33、 water meets the standards for physical, chemical and microbiological quality at the draw-off points; - all parts of the installation do not cause danger to health and do not damage property within calculated lifetimes: - the maintenance of the installation meets the functional requirements at all t
34、imes during its lifetime; - sound levels are kept to a practicable minimum; - 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,
35、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.
36、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
37、 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 followin
