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 approval before their acceptance as International Standards by the Iso Council. They are approved in accordance with ISO procedures requiring at least 75 % approval by the member bodies voting. International Standard ISO 1811-2 was prepared by Technical Committee ISO/TC 26, Copper and copper alloys. Together with ISO 1811-1 and 1811-3, it cancels and replaces ISO Recommendation R 1811 : 1971, of which it constitutes a technical revision. Iso 1811 consists of the following parts, under the general title Copper and copper alloys - Selection and preparation of samples for chemical analysis: Part 1 : Sampling of cast unwrought products Part 2 : Sampling of wrought products and castings Part 3 : Sampling of cathodes ?
