The work of developing International Standards is carried out through IsO Technical Committee. Every Member Body interested in a subject for which a Technical Committee has been set up has the right to be represented on that Committee. International organizations, governmental and non-governmental, in liaison with sO, also take part in the work. Draft International Standards adopted by the Technical Committees are circulated to the Member Bodies for approval before their acceptance as International Standards by the ISO Council. International Standard ISO 3644 was drawn up by Technical Committee ISO/TC 36, Cinematography, and circulated to the Member Bodies in February 1975. It has been approved by the Member Bodies of the following countries : Australia India Sweden Austria Italy Switzerland Turkey Belgium Japan Canada Netherlands United Kingdom Czechoslovakia U.S.A. Romania Denmark South Africa, Rep. of U.S.S.R. France Spain Yugoslavia No Member Body expressed disapproval of the document. @ International Organization for Standardization, 1976 : Printed in Switzerland Copyright International Organization for Standardization Provided by IHS under license with ISO No reproduction or networking permitted without license from IHS Not for Resale ISO3644-1976 (E) INTERNATIONAL STANDARD -E 4851903 0027012 1 Cinematography - Spindles for 8 mm Type R motion-picture cameras and projectors - Dimensions 1 SCOPE AND FIELD OF APPLICATION 3 Dimension C represents the diameter of the spindle shaft, excluding key, drive lugs, and locking means.
