12、The work of preparing International 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, governmental and non-g

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2
14、. 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

17、rrect the results of certain analytical determinations, e.g. volatile matter and hydrogen, for the effect of water in the determination and to allow all determinations to be corrected to a dry basis. Since coke is hygroscopic, its moisture varies with a change in humidity of the atmosphere, and it i

If test portions for several analytical determinations are weighed out at the same time, a single simultaneous moisture determination suff
