10、2:(3002E) 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
11、body interested 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 Electr
12、otechnical 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
13、 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 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
14、rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 9398-2 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 accessori

25、(55 1) % after rinsing in water and suitable extraction. This moisture level may also be expressed as a level of 51 % with respect to a dried mass which has regained moisture to a level of () 1 0 8% . +4.1.4 Number of loads Two identical loads, as defined in 4.1.1, shall be tested. If the test loads
26、, conditioned in accordance with 4.1.3, have to be kept for a period of time in the area where the tests are carried out, they shall be stored under a cover which will prevent any evaporation. 4.2 Energy supply Energy for the test shall be supplied by steam, gas, electricity or heat-transport fluid,
27、 as specified by the manufacturer. 4.3 Temperature of rinse water before extraction The temperature of the rinse water used in the test shall be (17 3) C before extraction.
