12、word ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a techn
13、ical committee has been established 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. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
14、electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requi

18、trolled Copy, (c) BSI iv Introduction Carbon reacts with carbon dioxide according to the following equation: CCO2 CO 2 ? The loss of anode material from reaction with CO2under certain constant conditions, as well as the mass of the remaining specimen and of the dust resulting from selective burning,
19、 are of importance in predicting the behaviour of the anodes in the electrolysis cell.
