Price based on 1 page Foreword Iso (the International Organization for Standardization) is a worldwide federation of national standards institutes (iso member bodies). The work of developing Inter- national Standards is carried out through ISO technical committees. Every member body interested in a subject for which a technicat committee has been set up 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. Draft International Standards adopted by the technical committees are circuiated to the member bodies for approval before their acceptance as International Standards by the ISo Council. International StandardISO3443/5wasdevelopedbyTechnical Committee iso/Tc 59, Building construction, and was circulated to the member bodies in November 1981. It has been approved by the member bodies of the following countries : Australia Finland Korea, Rep. of Austria France New Zealand Beigium Germany, F. R. Norway Brazil Hungary Poland Canada India Romania Czechoslovakia Iraq South Africa, Rep. of Denmark Israel Sweden Egypt, Arab Rep. of Italy Thailand Ethiopia Japan USSR The member bodies of the following countries expressed disapprovai of the document on technical grounds : Ireland Netherlands United Kingdom @ International Organization for Standardization, 1982 Printed in Switzerland INTERNATIONALSTANDARD ISO 3443/5-1982 (E) Building construction - Tolerances for building Part 5 : Series of values to be used for specification of tolerances o Introduction 2 References This International Standard forms one of a series concerning ISo 1803, Tolerances for building - Vocabulary.2) tolerances for building and building components.
