The work of preparing Intern
9、ational 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, governmental and non-governmental, in liaison with
10、 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 ISO/IEC Directives, Part 2. The main task of technical
11、 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 member bodies casting a vote. Attention is drawn to
12、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.

15、in terms of the needle pitch or gauge E and the machine nominal diameter, and is able to be used as a basis for the comparison of fabrics knitted on these machines. It is not applicable to circular knitting machines with a selection of single needles. 2 Normative references The following referenced

18、given in ISO 7839 apply. 4 Number of needles 4.1 General The numerical designations of the nominal diameters of circular knitting machines and the needle pitches shall be in accordance with ISO 8117 and ISO 8188. To determine the usual number, N u(rounded number), of needles for circular knitting ma
19、chines of large nominal diameter from the theoretical number, N t , of needles, take, as the divisor, a) 12, for machines with nominal diameters u 508 mm, and b) 24, for machines with nominal diameters 508 mm. The deviation from the theoretical number of needles shall not exceed 3 9 + in the case of
20、 a) and 6 18 + for b). NOTE 1 The usual number (rounded) of needles is therefore a multiple of 12 or 24 that occurs in the fixed tolerance interval for the theoretical number of needles, i.e. 3 9 + or 6 18 + .

21、om the theoretical number of needles can occur in the case of machines with a selection of single needles. 4.2 Calculation The theoretical number of needles, N t , of a needle carrier is obtained using the following formula: N t= d c E where = 3,141 592 7; d cis the designation for the nominal diame
22、ter of the knitting machine; E is the gauge. The usual number, N u , of needles (see Table 1) is the rounded number according to 4.1. EXAMPLE The theoretical number of needles for a knitting machine with a numerical designation d c= 18 and a gauge of E = 24 is N t= 18 3,141 592 7 24 = 1 357,168 The
23、usual number of needles is therefore in the range of 1 348,168 to 1 360,168 (i.e. 1 357,168 3 9 + ) and, in this example (using 12 as the divisor), is 1 356.
