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 committee. International organizations, govern- mental and non-governmental, in liaison with Iso, 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. They are approved in accordance with ISo procedures requiring at least 75 % approval by the member bodies voting. International Standard ISO 7740 was prepared by Technical Committee ISO/TC 170, Surgical instruments. Users should note that all International Standards undergo revision from time to time and that any reference made herein to any other International Standard implies its latest edition,unless otherwise stated. ?

Scalpel blades and handles currently in use are manufactured with fitting dimensions that do not always ensure a satisfactory fit be- tween blades and handles manufactured in different countries or by different manufacturers. A transitional period during which the fitting dimensions specified in this International Standard may be gradually adopted should last for five years and ends therefore on 31December1990. Scopeandfieldofapplication This International Standard lays down the dimensions of two sizes of fitting features for detachable scalpel blades and the handles with which they are used.
