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. Internationa! Standard ISO 8319/2 was prepared by Technical Committee ISO/TC 150, Implants for surgery. 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. @ International Organization for Standardization, 1986 Printed in Switzeriand Copyright International Organization for Standardization rmitted without license from IHS Not for Resale 8319 PT 2-86 2900 E0658h ISO 8319/2-1986 (E) INTERNATIONAL STANDARD Orthopaedic instruments - Drive connections Part 2: Screwdrivers for single slot head screws, screws with cruciate slot and cross-recessed head screws O Introduction screws with single slot heads, with cruciate slot or cross- recessed heads.
