21、ordISO (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 through ISO technical committees. Each member body interested in a subject for which a technic
22、al 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 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of el
23、ectrotechnical 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 Standards. Draft International Standards adopted by the technical committees are circulated to the
24、 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 of this document may be the subject of patent rights. ISO shall not be held responsible for ident
25、ifying any or all such patent rights.ISO 28017 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee SC 1, Hoses (rubber and plastics).This second edition cancels and replaces the first edition (ISO 28017:2009), which has been technically revised. The main changes a
26、re the following: 5.1: minimum lining thicknesses have been specified for hoses of different nominal sizes; 5.2: additional requirements have been specified for flotation materials; Clause 6: tighter tolerances have been specified for the inside diameters of all nominal sizes; 7.1.2: requirements ha
27、ve been included for the tear strength of the hose lining; 7.1.3: requirements have been included for the rebound resilience properties of the hose lining; 7.2.5: the requirements concerning minimum reserve buoyancy have been made clearer; 7.2.6: the flotation material recovery test procedure has be
28、en made clearer; 7.2.9: requirements have been included for the minimum tensile strength of empty hose assemblies; 7.3: a more detailed description of type test requirements has been given; Annex A: a tear strength test and a rebound resilience test of the lining compound have been included, as well
29、 as a tensile-strength test on empty hose assemblies; a new annex (Annex C) specifying a tensile-strength test has been added.ISO 28017:2011(E)iv ISO 2011 All rights reservedCopyright European Committee for Standardization Provided by IHS under license with CENNot for ResaleNo reproduction or networ

31、e grades of wire- or textile-reinforced dredging hoses with nominal sizes ranging from 100 to 1 200. Within each class, all grades and sizes have the same maximum working pressure. Such hoses are suitable for the delivery or suction of seawater or freshwater mixed with silt, sand, coral and small st
32、ones with a specific gravity in the range from 1,0 to 2,3 at ambient temperatures ranging from -10 C to +40 C.This International Standard covers two types of hose, as follows: type 1: floating type, for delivery only, which includes flotation material to give the hose buoyancy; type 2: submarine typ
33、e for delivery and suction.This International Standard does not specify requirements concerning the service life of hoses or hose assemblies. Specifying such requirements is the responsibility of the customer, in consultation with the hose manufacturer.2 Normative referencesThe following referenced
