12、 bodies). The work of preparing International Standards 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
13、 and non-governmental, in liaison with ISO, also 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 Directiv
14、es, Part 2. The main task of technical committees 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
15、casting a vote. Attention is drawn to the possibility 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 16136 was prepared by the European Committee for Standardization (CEN) Technical
16、Committee CEN/TC 69, Industrial valves, in collaboration 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 Ag

18、(E) ISO 2006 All rights reserved 1 Industrial valves Butterfly valves 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 cont
19、rol service, their connection to the pipe system, the body materials and their pressure/temperature rating between 40 C and + 120 C, 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 p
20、ipe systems, irrespective of the field of application 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 Internati
21、onal Standard is concerned with the range of DN DN 15, DN 20, DN 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 refer
