The work of preparing International Standards is no
4、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, govern- mental and non-governmental, in liaison with ISO, also take part
5、in 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 Inter- national Stand
6、ard requires approval by at least 75 % of the member bodies casting a vote. International Standard IS0 8758 was prepared by Technical Committee ISO/TC 36, Cir?ernatography. Annex A of this International Standard is for information only. 0 tso 1992 All rights reserved. No part of this publication may

10、m motion-picture camera negatives and 35 mm motion-picture release prints. It also specifies the width scanned by the control data reproducer, and the reproducer spectral sensi- tivi ty.
