The work of preparing Internationat Standards is normally carried out through ISO technical committees. 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, aiso 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 least 75 % approval by the member bodies voting. international Standard iSO 2093 was prepared by Technical Committee iSO/TC 107, Metallic and other non-organic coatings. This second edition cancels and replaces the first edition (IS0 2093-1973), of which it constitutes a technicai revision. Users shouid note that all nternationai Standards undergo revision from time to time and that any reference made herein to any other International Standard implies its latest edition, unless otherwise stated. ?
