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, govern- mental 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 electrotechnical standardization. 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. International Standard ISO 1082 was prepared by Technical Committee ISO/TC 82, Mining. This second edition cancels and replaces the first edition (IS0 1082 : 1984), of which it constitutes a minor revision. All references to ISO/R 147 have been replaced by a referencetoiso7500-1. ?
