6、 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 that

7、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 in acc

8、ordance 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 requ

34、as given in Table 5 (column D). NOTE 2 When either only a minus or plus side tolerance is specified, the value in this table shall be doubled. aThe circumscribing circle is the smallest circle which encloses entirely the cross-section of the shape. However, this dimension may have to be increased wh

35、en shapes are subjected to corrections of the uneven thickness or in the case of hollow shapes for which the centre of the circumscribing circle needs to be considered, based on the void. These matters should be confirmed with the supplier beforehand as required. bWhen the dimensional tolerance is n

36、ot made equal at the plus side and minus side, determine the value in the column corresponding to the centre of allowable range, and use this value as a standard to decide the tolerance. cIn the case of angled shapes as shown in Figure 3, the tolerances shall be decided not on the base of the length

37、 of dimension X, but on the base of the angle (see 6.6). dEven when value Y in Figure 3 is equal to or greater than 75 % of value X, these tolerances are not applied to the dimension X or Z. The tolerances for X and Y shall conform to the column corresponding to space dimension C iand C edepending o

38、n the distance from the reference base. eIf the purchaser and the supplier agree, the outside dimension C emay be specified instead of the inside dimension C i . fThis is applicable when the space volume enveloped with hollow part is 70 mm or larger. If less than 70 mm 2 , employ column A. gIf 5 mm
