The work of developing International Standards is carried out through Iso Technical Committees. Every up has the right to be represented on that Committee. International organizations, governmenta! 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. Prior to 1972, the results of the work of the Technicat Committees were published as Iso Recommendations; these documents are now in the process of being transformed into International Standards. As part of this process, Technical Committee 1SO/TC 82 has reviewed ISO Recommendation R 710/l and found it suitable for transformation. International Standard ISO 710/l therefore replaces isO Recommendation R 710/1-1968. following countries : Hungary Belgium Portugal Brazil India Spain Chile South Africa, Rep. of Italy Czechoslovakia Japan Sweden Egypt, Arab Rep. of Korea, Rep. of Turkey France Netherlands U.S.S.R.

For this reason the relevant parts of In many spheres of technology, science and economics, IsO 710 are limited to the establishment of ornaments for data on the geological formations and structure of the the most important and the most frequently occurring earth's crust are indispensable. Often, this information is rocks, and are based on the following principles : given in the form of maps and plans annotated by a) In order to characterize the properties of rocks, conventional symbois. elementary symbols are chosen which shall Until the present time, different symbols have been used, be as simple as possible and therefore easily not only from country to country, but often for various fields of application within the same country, the result traceable; being entirely different representations of the same facts or express the nature of the rock in question; geological data. Under these circumstances, it has become necessary to eliminate these differences as far as possible be of such a dimension that several elementary and to reach some agreement on the use of a standard set of symbols may be placed next to each other on the symboils and ornaments, so that
