21、his International Standard and the EssentialRequirements of EU Directive 97/23 EC (PED). 15EN ISO 16136:2006iv Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards i
22、s 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, also take par
23、t 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 committees is to p
24、repare 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 possibility tha

ISO 16136 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 69, Industrial valves, in collaboration
26、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、alves of thermoplastics materials 1 Scope This International Standard specifies requirements for the design, functional characteristics and manufacture of butterfly valves made of thermoplastics materials intended for isolating and control service, their connection to the pipe system, the body mater
28、ials 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 and the fl
29、uids 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 15, DN 20, DN
30、 25, DN 32, DN 40, DN 50, DN 65, DN 80, DN 100, DN 125, DN 150, DN 200, DN 250, DN 300, DN 350, DN 400, DN 450, DN 500 and DN 600 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 do
