20、r 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 the

21、 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.Internatio

22、nal 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. Publication as

23、 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.ISO

26、onIt was decided to produce an International Standard under the Vienna Agreement on technical cooperation between ISO and the European Committee for Standardization (CEN) in order to maintain a unique EN ISO document.The major changes in this revision of this International Standard are the following

27、: update of the structure of the International Standard; update of the test and performance requirements to reflect the practice of the industry at the time of publication; introduction of an evaluation of conformity and a system of certification.This International Standard is a base standard for co

28、rrugated metal hoses and hose assemblies for general purpose.Corrugated metal hoses and metal hose assemblies conforming to all aspects of this International Standard are considered to be designed and manufactured to sound engineering practice.The requirements of this International Standard are of i

29、mportance to designers, manufacturers, users, suppliers and importers of corrugated metal hoses.Non-permanent, detachable connections between hoses and fittings are available in the market.
