7、dwide 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 right to be represented on
8、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. International Standards are drafted i
9、n 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 an International Standard
10、 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 1704 was prepared by Tec
11、hnical Committee ISO/TC 8, Ships and marine technology, Subcommittee SC 4, Outfitting and deck machinery. This third edition cancels and replaces the second edition (ISO 1704:1991) which has been technically revised as follows. Tolerances on the nominal diameter of the links remain the same, but tol
12、erances on other parts of the links have been appropriately adjusted. Lengths and tolerances of the combined links have been increased. The allowable manufacturing tolerance of all other dimensions has been increased. The nominal diameter of a common stud link is shown by d and the diameter of other
13、 links, shackles and swivels given as multiples of d. The swivel type and a series of its dimensions have been added for the convenience of the user. The patented swivel or the swivel with a particular function can be used as a substitute if this is possible in harmony with this International Standa

20、 prevents excessive twisting of the chain cable 3.8 outboard chain-shot additional short chain-shot fastened to the anchor shackle 3.9 nominal size nominal diameter of the common stud link 4 Shape and dimensions 4.1 Shape The stud links, shackles and component parts shall be of the shapes and propor
21、tions shown in Figures 1 to 9. 4.2 Dimensions 4.2.1 General The dimensions of stud links, shackles and component parts shall be in accordance with the values given in Tables 1 to 7. The nominal diameter, d, is a design diameter measured at the crown of a common stud link as an average value of two m
22、easurements perpendicular to each other. See Figure 1 and Table 1. All dimensions, based on the nominal diameters, d, of the common stud links, shall be measured after the chain and shackles have been subjected to the statutory proof loads. 4.2.2 Enlarged stud links The proportions of the enlarged s
23、tud links are the same as those of the common stud links. The nominal diameter of the enlarged stud link is 10 % larger than the nominal diameter of the common stud link: d1= 1,1 d, the calculated values are rounded to the nearest nominal diameter of the common link. 4.2.3 Common stud links and enla
24、rged stud links The inside diameter of common stud links and enlarged stud links shall be sufficient to allow each link to bed properly and work freely. See Figures 1 and 2. 4.2.4 End links The inside diameter of end links shall be sufficient to allow the shackle link to bed properly and work freely
25、. See Figure 3. The nominal diameter of the end link is 20 % larger than the nominal diameter of the common stud link: d2= 1,2 d, the calculated values are rounded to the nearest nominal diameter of the common link. 4.2.5 Shackle retaining pin The retaining pin used in “D” type joining shackles and
26、end shackles shall be a taper pin having a taper of not less than 1:50 and not more than 1:16 on the diameter. BS ISO 1704:20083The retaining pin used in Kenter type shackles shall be a taper pin having a taper of not less than 1:50 and not more than 1:32 on the diameter. The nominal diameter of the
27、 taper pin shall be 0,37 d, the calculated values are rounded to the nearest standardized nominal diameter in accordance with ISO 2339. The nominal length of the taper pin shall be (w4 2) nominal diameter to taper pin (see Figure 5), the calculated values are rounded to the nearest standardized nomi
28、nal length in accordance with ISO 2339. Nominal sizes and lengths required are given in Tables 4, 5 and 6. Other details of the taper pins, e.g. end radius, cone tolerance and surface finish, shall be in accordance with ISO 2339. Taper pins shall be either of stainless steel or tin-coated carbon ste
29、el. If tin-coated, this shall be either by a hot-dip process or electroplating in accordance with ISO 2093:1986, 7.1, service condition 4. 5 Tolerances 5.1 Nominal diameter of common stud links The allowable manufacturing tolerances on the nominal diameter d of the common stud links, measured at the
30、 crown, are 01mmfor d u 40 mm; 02mmfor 40 mm 122 mm. The cross-sectional area at the crown of the link shall be not less than the area of a circle of the nominal diameter. The allowable manufacturing tolerance on the nominal diameter measured elsewhere on the link is 50%.+The tolerance on the stud-l
31、ink welded parts is +15 %. The allowable manufacturing tolerance of the link except for the requirements specified above is 2,5 %, taking into account the fact that all components of the anchor chain shall fit in with each other. 5.2 Length of five links The length of five links is defined as 5 p +
32、2 d = 22 d. The measurement is taken from the outside. The allowable manufacturing tolerance on a length of five links is 2,50%.+5.3 All other dimensions The tolerances of the diameter: 5%0+The tolerances other than diameter: 2,5 %. BS ISO 1704:20084 6 Range of sizes of links and shackles The range
33、of nominal diameter, d, is that specified by the classification societies associated in the International Association of Classification Societies (IACS). 7 Designation of size The nominal size of a common stud link is designated its nominal diameter, d. The nominal size of other links, shackles and
34、swivels is designated by the nominal diameter, d, of the common stud link. The nominal size of a stud-link anchor chain is designated by the nominal diameter of the common stud link. 8 Connections Examples in the use of connecting chain-shots with joining shackle are shown in Figure 8. Examples in t
