21、nternational Standard and theEssential Requirements of EU Directive 97/23 EC (PED) . 15ivForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out

22、 through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO col

23、laborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International S

24、tandards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements

25、 of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

27、terials 1 Scope This International Standard specifies requirements for the design, functional characteristics and manufacture of check valves made of thermoplastics materials intended to allow the flow of liquid fluids through the valve in one direction only and to prevent backflow, their connection

28、 to the pipe system, the body materials and their pressure/temperature rating between 40 qC and 120 qC, for a lifetime of 25 years, and also specifies their tests. This International Standard is applicable to valves to be installed in industrial pipe systems, irrespective of the field of application

29、 and the fluids to be conveyed. NOTE 1 Industrial pipe systems also include systems for water supply for general purposes, drainage and sewerage. NOTE 2 Special requirements can apply to pipe systems for water for human consumption. This International Standard is concerned with the range of DN DN 8,
