The work of preparing International Standards is normally carried out through ISO non-governmental, in liaison with isO, also take part in the work. sO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/lEC Directives, Part 2 The main task of technical committees is to prepare International Standards. 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.

ISO 1920-9 was prepared by Technical Committee ISO/Tc 71, Concrete, reinforced concrete and pre- stressed concrete, Subcommittee SC 1, Test methods for concrete. Iso 1920 consists of the following parts, under the general title Testing of concrete: Part 1: Sampling of fresh concrete Part 2:Properties of fresh concrete Part 3: Making and curing test specimens Part 4: Strength of hardened concrete Part 5: Properties of hardened concrete other than strength Part 6: Sampling, preparing and testing of concrete cores Part 7: Non-destructive tests on hardened concrete Part 8: Determination of drying shrinkage of concrete for samples prepared in the field or in the laboratory Part 9: Determination of creep of concrete cylinders in compression The following part is under preparation: Part 10:Determination of static modulus of elasticity in compression @ ISO 2009 - All rights reserved ili
