The work of developing International Standards is carried out through ISO Technical Committees. Every Member Body interested in a subject for which a Technical Committee has been set up has the right to be represented on that Committee. International organizations, governmental 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. Standard ISO 2947 was drawn up by Technical _ International Committee ISO/TC 38, Textiles, and circulated to the Member Bodies in August 1972. It has been approved by the Member Bodies of the following countries : India Spain Australia Austria Ireland Sweden Belgium Switzerland Israel Japan Thailand Canada Czechoslovakia Mexico Turkey Netherlands Denmark United Kingdom Egypt, Arab Rep. of New Zealand U.S.A.

The rounded values included for denier To facilitate the implementation of the Tex System the numbers form a limited selection from the range of conversion table which is the subject of this International "Continental Rounded Decitex Values", which embraces Standard has been developed with the collaboration of the bulk of deniers produced and is already in use by the experts from the following international organizations : major man-made fibre producers. Association Europeenne de Moulinage To ensure a smooth transition to the Tex System it is -- Association of European Jute Industries necessary to maintain a degree of flexibility in regard to both the choice of unit and satisfying the reasonable Comite International de la Rayonne et des Fibres requirements of spinners' customers. Adoption of the Synthétiques (CIRFS) rounded values in the conversion table would, however, make a substantial contribution to rationalization since 466 Eurocoton traditional yarn counts would be replaced by 205 rounded Féderation Internationale de la Filterie tex values. When the Tex System has been fully adopted, it is hoped International Association of Users of Man-made that a range of tex values will ultimately evolve which will Fibres (AIUFFAS) have more rational intervals between linear densities than International Bureau for the Standardization of those determined pragmatically and embodied in this Man-made Fibres (BISFA) International Standard.
