The work of preparing International Standards i
3、s normally 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 rep- resented on that committee. International organizations, governmental and non-governmental, in liaison with KO, also take pa
4、rt 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 International Stan
5、dard requires approval by at least 75 % of the member bodies casting a vote. International Standard IS0 831 9-1 was prepared by Technical Committee ISO/TC 150, Implants for surgery, Subcommittee SC 5, Osteosynthesis.

9、that a) the working end of the screw key should accurately engage the head of the screw; b) the materials used for the manufacture of the screw keys should be satisfactory from all clinical aspects; c) the screw key should have adequate strength. The purpose of this part of IS08319 is to ensure that
10、 this is achieved without imposing undue restriction on design features. . 111 IS0 8319-1 96 4851903 O660328 079 INTERNATIONAL STANDARD IS0 IS0 8319-1:1996(E) Orthopaedic instruments - Drive connections - Part 1: Keys for use with screws with hexagon socket heads 1 Scope This part of IS0 8319 specif
