The work of preparing International Standards
12、 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, governmental and non-governmental, in liaison with ISO, also take p
13、art in the work. ISO 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/IEC Directives, Part 2. The main task of technical committees is to
14、 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. Attention is drawn to the possibility t

ISO 1920-5 was prepared by Technical Committee ISO/TC 71, Concrete, reinforced concrete and pre-stressed concrete, Subcommittee SC 1, Test m

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 a

For undated reference
20、s, the latest edition of the referenced document (including any amendments) applies. ISO 1920-3, Testing Concrete Part 3: Making and curing test specimens 3 Definitions For the purpose of this document, the following definition applies. 3.1 density ratio of the mass of a given quantity of hardened c
21、oncrete to its volume NOTE The density is expressed in kilograms per cubic metre. 4 Determination of density of hardened concrete 4.1 General This test method is applicable to lightweight, normal-weight and heavy-weight concrete. It differentiates between hardened concrete in the following states: a
22、s-received; saturated; oven-dried. The mass and the volume of the specimen of hardened concrete are determined and the density calculated. 4.2 Apparatus 4.2.1 Callipers and rules, capable of determining the dimensions of a specimen to within 0,5 %.
