The work of preparing International Standards is no
20、rmally carried out through IS0 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 nongovernmental, in liaison with ISO, also take part in
21、the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard r
22、equires approval by at least 75 % of the member bodies casting a vote.

30、tive deviations; b) placed with, or adjacent to, the caption of the figure when limit deviation information applies only to sizes within that figure (for example, a cross-section detail); c) placed with, or adjacent to, the size concerned when limit deviation information applies only to that size. 5
31、.2 Limit deviations for size shall be indicated by the target size and the limit deviations. The target size and the values of limit deviations shall be given in millimetres (see figures 1 and 2). In the case of angles, the target size and the limit deviations should preferably be given in degrees,
32、but may be given, if necessary, in gon. Limit deviation information which is shown on drawings should be given in accordance with the example shown in figure 1 a) for a symmetrical limit deviation and in accordance with figure 1 b) or figure 1 c) for an asymmetrical limit deviation. *s 890112 1; 890
