21、al Organization for Standardization) is a worldwide federation of national standards bodies (ISO member 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 e
22、stablished 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 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standard
23、ization. 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 Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for vo
24、ting. 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 of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all su
25、ch patent rights. ISO 10931 was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the transport of fluids, Subcommittee SC 3, Plastics pipes and fittings for industrial applications. This first edition of ISO 10931 cancels and replaces ISO 10931-1:1997, ISO 10931-2:
26、1997, ISO 10931-3:1996, ISO 10931-4:1997 and ISO 10931-5:1998, of which it constitutes a technical revision. BS EN ISO 10931:2005vIntroduction This International Standard specifies the characteristics and requirements for a piping system and its components made from poly(vinylidene fluoride) (PVDF)
27、intended to be used for industrial applications, above-ground, by authorities, design engineers, certification bodies, inspection bodies, testing laboratories, manufacturers and users. At the date of publication of this International Standard, International Standards for piping systems of other plas
28、tics used for industrial applications were ISO 15493, for acrylonitrile-butadiene-styrene (ABS), unplasticized poly(vinyl chloride) (PVC-U), chlorinated poly(vinyl chloride) (PVC-C) and ISO 15494, for polybutene (PB), polyethylene (PE), polypropylene (PP).

29、ystems for industrial applications Poly(vinylidene fluoride) (PVDF) Specifications for components and the system IMPORTANT Requirements for industrial valves are given in this International Standard and/or in other International Standards. Valves may be used with components conforming to this Intern
30、ational Standard provided they conform additionally to its relevant requirements. Where existent, national regulations for specific applications (e.g. water treatment) apply. Other application areas are permitted if the requirements of this International Standard and/or applicable national requireme
31、nts are fulfilled. Relevant regulations in respect of fire behaviour and explosion risk are applicable if applications are envisaged for inflammable media. Components conforming to any of the product standards listed in the Bibliography or to national standards, as applicable, may be used with compo
32、nents conforming to this International Standard, provided they conform to the requirements for joint dimensions and the relevant requirements of this International Standard. 1 Scope This International Standard specifies the characteristics and requirements for components such as pipes, fittings and
33、valves made from poly (vinylidene fluoride) (PVDF), intended to be used for thermoplastics piping systems in the field of industrial applications above-ground. It is applicable to PVDF pipes, fittings, valves and ancillary equipment, their joints and to joints with components of other plastics and n
34、on-plastics materials, depending on their suitability, intended to be used for the conveyance of liquid and gaseous fluids as well as of solid matters in fluids for industrial applications including chemical plants, industrial sewerage engineering, power engineering (cooling and general purpose wate
35、r), electroplating and pickling plants, semiconductor industry, agricultural production plants, and water treatment. This International Standard is applicable to PVDF piping systems for use at temperatures up to 150 C. However, for applications above 120 C, which depend upon the crystalline melting
36、point of the PVDF material, it is advisable to seek the advice of the manufacturer of the component (the components have to withstand the mechanical, thermal and chemical demands to be expected and to be resistant to the fluids to be conveyed). Characteristics and requirements which are applicable f
37、or PVDF in general are covered by the relevant clauses of this International Standard. Those characteristics and requirements which depend on the material used are given in Annex A.
