17、es (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 the right to be represented on that committee. International organizations

18、, 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. International Standards are drafted in accordance with the rules given in the IS

19、O/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. Publication as an International Standard requires approval by at least 75 % of the

20、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. ISO 1403 was prepared by Technical Committee ISO/TC 45, Rubber and rubb

22、general-purpose water applications Specification WARNING Persons using this International Standard should be familiar with normal laboratory practice. This standard does not purport to address all the safety problems, if any, associated with its use. It is the responsibility of the user to establish

23、 appropriate health and safety practices and to ensure compliance with any national regulatory conditions. 1 Scope This International Standard specifies the requirements for three types of general-purpose textile-reinforced rubber water hose with an operating temperature range of 25 C to +70 C and a

24、 maximum working pressure of up to 25 bar 1). These hoses are not intended to be used for conveyance of potable (drinking) water, for washing-machine inlets, as firefighting hoses, for special agricultural machines or as collapsible water hoses. These hoses may be used with additives which lower the

25、 freezing point of water. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.
