10、) vi I SO 3002 All irhgts seredevrForeword ISO (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 int
11、erested in a subject for which a technical 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 Electrotechnic
12、al Commission (IEC) on all matters of electrotechnical 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
13、technical committees are circulated to the 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.
14、ISO shall not be held responsible for identifying any or all such patent rights. ISO 9398-1 was prepared by Technical Committee ISO/TC 72, Textile machinery and machinery for drycleaning and industrial laundering, Subcommittee SC 5, Industrial laundry and dry-cleaning machinery and accessories. This
15、 second edition cancels and replaces the first edition (ISO 9398-1:1993), which has been technically revised.
