The work of preparing International Standards is normally carried out through
11、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, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates
12、 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 ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards.
13、 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 member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this
14、document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 9398-4 was prepared by Technical Committee ISO/TC 72, Textile machinery and machinery for drycleaning and industrial laundering, Subcommittee SC 5, Industrial laundry an
15、d dry-cleaning machinery and accessories. This second edition cancels and replaces the first edition (ISO 9398-4:1993), which has been technically revised.

39、sion. 5.1.3 Ascertain the mean value of the three extraction tests specified in 5.1.2. 5.2 Expression of results Indicate the mean residual moisture value of the test load after extraction, as determined in 5.1. 6 Energy consumption of machine 6.1 General The energy consumption of a washer-extractor
40、 is defined as the number of kilojoules or kilowatt hours of steam, gas, electricity or heat-transport fluid energy required during washing and extraction of a load (see 4.1) in a machine operating at its nominal capacity during the time corresponding to cycle A, B or C (see 6.3). 6.2 Test method 6.
41、2.1 Under the general test conditions specified in Clause 4, carry out one test cycle (either cycle A, B or C) with one test load (see 4.1) in order to condition the machine. 6.2.2 Run the cycle chosen in 6.2.1 three times in succession, using the same test load (see 4.1). 6.2.3 Using suitable instr
42、uments, check the values of parameters allowing the calculation of the corresponding energy consumption for a determined cycle (A or B or C) and take the mean value of the three tests. For machines using electric or gas energy for heating, energy meters are reliable; for machines using steam as the
43、heat source, for the preliminary wash and main wash, measure the water quantities to be heated, as well as the temperatures before and after steam injection. 6.3 Expression of results 6.3.1 Indicate the energy consumption, expressed as kilojoules or kilowatt hours, per kilogram, for the washing and
44、extraction of a test load of decatized cotton sheets in accordance with 4.1 (cycle A, B or C to be specified). 6.3.2 Indicate the energy consumption required by the motor or motors for the mechanical drive of the cage during the washing/extraction phases. 6.3.3 The total energy consumption required
45、by washer-extractor is the sum of the mechanical and thermal energies required.

46、th washing and rinsing) of a washer-extractor is defined as the number of litres of water necessary for washing one test load (see 4.1) in a machine operating at its nominal capacity in the specified test cycle (see 4.6 and 7.3). 7.2 Test method 7.2.1 Under the general test conditions as specified i
47、n Clause 4, carry out one cycle (A, B or C) with one load (see 4.1) to condition the machine. 7.2.2 Run the cycle chosen in 7.2.1 three times in succession, using the same test load as specified in 4.1. 7.2.3 Using suitable instruments, record the corresponding water consumption required for each of
48、 the three tests and take the mean value. 7.3 Expression of results Indicate the water consumption, expressed in litres per cycle (A, B or C to be specified) and per kilogram, required for the washing and extraction of decatized cotton sheets as specified in 4.1. 8 Hourly productivity of machine 8.1 General The hourly productivity of a washer-extractor is defined as the mass, in kilograms, of a load of decatized cotton sheets as specified in 4.1 that can be washed and extracted in 1 h, not including the time for loading and unlo
