The work of preparing International Standards is normally carr
10、ied 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 non-governmental, in liaison with ISO, also take part in the work.
11、IS0 collaborates closely with the International Electrotechnical Commission (I EC) 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 Interna
12、tional 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 the possibility that some of the

39、Adjust the endoscope holder by looking through the endoscope, so that the circles marked on the target and the circumference of the field of view are centred. 4.4 Determine the largest visible circle and record it as the field of view, in degrees. For a non-circular image, only segments of the large
40、st circle may be visible. 4.5 Read and record as the direction of view the angular position, in degrees, of the protractor relative to the perpendicular axis of the endoscope. 4.6 Repeat steps 4.3 to 4.5 until a sufficient number of results have been obtained to verify the required statistical accur
41、acy of the endoscope. 2 Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=NASA Technical Standards 1/9972545001 Not for Resale, 04/22/2007 21:53:05 MDTNo reproduction or networking permitted without license from IHS -,-,- Q IS0 IS0 8600-3: 1 997
