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. Iso collaborates closely with the International Electrotechnical Commission (lEC)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 Inter- national Standardrequires approval by at least 75%of themember bodies casting a vote. mittee iso/Tc 10, Technical drawings, product definition and related documentation, Sub-Committee Sc 6, Mechanical engineering docu- mentation. which it constitutes an extension and technical revision.
