23、rd 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 pi
24、pes, 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
25、 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.

32、06-1:2000 3 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 po
33、table 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
34、times 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, e.
35、g. persons with relevant experience, qualifications 1), 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 W
36、ater 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 pr
37、ivate 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 t
38、erms 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 relevant regulations based on ECC directives The water may also be used for washing, cooking and sanitary purposes (at temperatures up to 95
