18、n 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 established has
19、 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 standardization.Intern
20、ational 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 voting. Publicatio
21、n 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 such patent rights.
22、ISO 6224 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee SC 1, Hoses (rubber and plastics).This fourth edition cancels and replaces the third edition (ISO 6224:2005), which has been technically revised. The main changes are as follows: Table 1 includes four ad
23、ditional inside diameters (4 mm, 6 mm, 8 mm and 9 mm) for each type of hose; in Table 3, the requirement for the minimum adhesion between components has been raised from 1,5 kN/m to 2,0 kN/m; annexes giving schedules for type, routine and production testing have been added.ISO 6224:2011(E)iv ISO 201

It is the responsibility of the user to establish appropriate health and safety practices and to ensure compliance with any national regulatory conditions.1 ScopeThis International Standard specifies the requirements for gene
26、ral-purpose textile-reinforced thermoplastics water-discharge hoses.Three types of hose are specified according to their operating duty requirements, i.e. their ambient and water temperature ranges: ambient temperatures: 10 C to +60 C; water temperature during operation: 0 C to +60 C.NOTE At water t
27、emperatures above 23 C and particularly above 40 C, the maximum working pressure will be reduced.These hoses are not intended to be used for conveyance of potable (drinking) water, for washing-machine inlets, as fire-fighting hoses, for special agricultural machines or as gardening hoses for the con
