The work of preparing International Standards is normally carried out through IsO establishedhastherighttoberepresentedonthatcommittee.Internationalorganizations,governmentaland non-governmental, in liaison with Iso, also take part in the work. Iso collaborates closely with the InternationalElectrotechnicalCommission(lEC)onallmattersofelectrotechnicalstandardization. International Standards are drafted in accordance with the rules given in the ISO/lEc Directives, Part 2. The main task of technical committees is to prepare International Standards. 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. To respond to the need for global collaboration on standardization questions at early stages of technological innovation, the ISO Council, following recommendations of the IsO/lEC Presidents' Advisory Board on Technological Trends, decided to establish a new series of isO publications named 'Technology Trends Assessments'(isO/TTA).Thesepublicationsaretheresultsofeitherdirectcooperationwith prestandardization organizations or ad hoc Workshops of experts concemed with standardization needs and trends in emerging fields. Technology Trends Assessments are thus the result of prestandardization work or research. As a condition of publication by ISO, ISO/TTAs shall not conflict with existing International Standards or draft International Standards(Dis),butshallcontaininformationthatwouldnormallyformthebasisof standardization.iSOhas decided to publish such documents to promote the harmonization of the objectives of ongoing prestandardization work with those of new initiatives in the Research and Development environment. It is intended that these publications will contribute towards rationalization of technological choice prior to market entry. Whilst ISO/TTAs are not Standards, it is intended that they will be able to be used as a basis for standards development in the future by the various existing standards agencies.
