Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

Members of clinic teams in different countries develop their own nomenclature to meet their own needs. Hence there is a need for an international system to be developed in order to compare one publication with another and one patient with another. The different care groups who would appreciate and use a standardized system of describing the reason for amputation and the general state of the patient include surgeons, other doctors (especially those concerned with rehabilitation), physical and occupational therapists and prosthetists. Such a system would also be of value to epidemiologists and government health officials. The system proposed has to meet the needs of the different members of the clinic team and to enable the description of the cause of amputation andtheunderlyingconditiontoberecorded inawaythatcanbeeasily incorporated in reports. This part of iSO 8548 deliberately aims at defining the minimum information to be described. It should be feasible for this information to be included in forms designed by the individual institution andbecapableof readyadaptationforcomputeranalysis
