21、etween this International Standard and the Essential Requirements of EU Directive 97/23 EC (PED) . 13EN ISO 16138:2006iv Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International S
22、tandards is normally carried out 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, als
23、o take part in the work. ISO collaborates 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 committe
24、es is to prepare International Standards. 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 possi
25、bility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 16138 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 69, Industrial valves, in coll
26、aboration with ISO/TC 138, Plastics pipes, fittings and valves for the transport of fluids, Subcommittee SC 7, Valves and auxiliary equipment of plastics materials, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

27、iaphragm valves of thermoplastics materials 1 Scope This International Standard specifies requirements for the design, functional characteristics and manufacture of diaphragm valves made of thermoplastics materials intended for isolating and control service, their connection to the pipe system, the
28、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 hand- or power-operated 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,
30、DN 10, DN 15, DN 20, DN 25, DN 32, DN 40, DN 50, DN 65, DN 80, DN 100, DN 125, DN 150, DN 200 and DN 250 and the range of PN and Class PN 6, PN 10, PN 16 and Class 150. 2 Normative references The following referenced documents are indispensable for the application of this document.
