Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). 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, governmental 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.
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 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 that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 1920-1 was prepared by Technical Committee ISO/TC 71, Concrete, reinforced concrete and pre-
stressed concrete, Subcommittee SC 1, Test methods for concrete.
This first edition of ISO 1920-1 cancels and replaces ISO 2736-1:1986, Concrete tests — Test specimens —
Part 1: Sampling of fresh 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 concrete cores
Part 7: Non-destructive tests on hardened concrete
INTERNATIONAL STANDARD ISO 1920-1:2004(E)
Testing of concrete —
Part 1:
Sampling of fresh concrete
WARNING — When cement is mixed with water, alkali is released. When sampling, prevent skin
contact with wet cement or concrete by wearing suitable protective clothing (gloves, footwear, safety
glasses). If wet cement or concrete enters the eye, immediately wash it out thoroughly with clean
water and seek medical treatment without delay. Wash wet concrete off the skin immediately.
1 Scope
This part of ISO 1920 specifies procedures for the sampling of fresh concrete. The samples are used for the
testing of properties of fresh concrete, or for making test specimens to determine the properties of hardened
concrete.
NOTE ISO 1920-1 specifies the properties of fresh concrete and ISO 1920-3 gives the procedures for making and
curing test specimens.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

ISO 1920-3, Testing of concrete — Part 3: Making and curing test specimens
ISO 1920-4, Testing of concrete — Part 4: Strength of hardened concrete
3 Terms and definitions
For the purpose of this document, the following terms and definitions apply.
3.1
batch
quantity of concrete, mixed in one cycle of operation of a batch mixer, or the quantity of concrete conveyed
ready-mixed in a vehicle, or the quantity discharged over 1 min from a continuous mixer
3.2
composite sample
quantity of concrete consisting of a number of increments, distributed through a batch or mass of concrete,
which are thoroughly mixed together
3.3
spot sample
quantity of concrete taken from part of a batch or mass of concrete, consisting of one or more increments that
are thoroughly mixed together
3.4
increment
quantity of concrete taken by the single operation of a scoop
4 Principle
4.1 Taking a composite sample
Concrete is sampled from a stream of moving concrete or from a pile in a series of increments according to
6.2. These increments are then thoroughly mixed together.
4.2 Taking a spot sample
Concrete is sampled from a stream of moving concrete or from a pile at a single point.
Spot samples are not representative of the batch and should not be used to manufacture strength specimens.
5 Apparatus
5.1 Scoop, made from non-absorbent material not readily attacked by cement paste, with a size suitable for
taking increments of concrete.
5.2 Containers, one or more, made from non-absorbent material not readily attacked by cement paste, for
receiving, transporting and remixing the concrete samples.
5.3 Thermometer (when required), to measure the temperature of fresh concrete to an accuracy of ± 1 °C.
5.4 Moist cloth.
6 Sampling procedure
6.1 Sampling plan
Decide whether a spot sample or a composite sample is to be taken.
