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. Draft International Standards adopted by the technical committees are circulated to the member bodies for approvat 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 5019/2 was prepared by Technical Committee ISO/TC 33, Refractories. It cancels and replaces Iso Recommendation R 1145-1969, of which it constitutes a technical revision.
