ISO INTERNATIONAL 6934-3 STANDARD First edition 1991-12-15 Steel for the prestressing of concrete -- Part 3: Quenched and tempered wire Acier pour armatures de precontrainte - Partie 3: Fil trempe et revenu Reference number ISO 6934-3:1991(E) Copyright International Organization for Standardization Not for Resale ISO 6934-3:1991(E) Foreword IsO (the International Organization for Standardization) is a worldwide federation of national standards bodies (lsO memberbodies).The work of preparing International Standards is normally carried out through Iso technical committees. Each member body interested in a subject for which a technica! 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 inter- national Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard isO 6934-3 was prepared by Technical Committee ISO/Tc 17, Steel, Sub-Committee SC 16, Steels for the reinforcement and prestressing of concrete. IsO 6934 consists of the following parts, under the general title Steel for the prestressing of concrete: Part 1: General requirements -- Part 2: Cold-drawn wire Part 3: Quenched and tempered wire -- Part 4: Strand Part 5: Hot-rolled steel bars with or without subsequent processing Annex A of this part of isO 6934 is for information only.
