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 1920-5 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 1920-5 cancels and replaces ISO 6275:1982 which has been technically revised.
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 5: Properties of hardened concrete other than strength
 Part 6: Sampling, preparing and testing concrete cores
 Part 7: Non-destructive tests of hardened concrete
Part 4, Strength of hardened concrete, is in preparation.

INTERNATIONAL STANDARD ISO 1920-5:2004(E)

Testing of concrete —
Part 5:
Properties of hardened concrete other than strength
1 Scope
This part of ISO 1920 specifies procedures for testing properties of hardened concrete other than strength.
2 Normative references
The following referenced document is essential for the application of this document. For undated references,
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 concrete 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:
 as-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 %.

---------------------- Page: 5 ----------------------
ISO 1920-5:2004(E)
4.2.2 Balance. equipped with a stirrup for weighing the specimen in both air and water to an accuracy of
0,1 % of the mass (see Figure 1).
4.2.3 Water tank, fitted with a device to maintain the water at a constant level and of sufficient size to allow
the specimen on the stirrup to be fully immersed to constant depth (see Figure 1).
4.2.4 Ventilated oven, for which the temperature can be maintained at 105 °C ± 5 °C.
4.3 Test specimens
The minimum volume of a specimen shall be 1 l. If the nominal maximum aggregate size exceeds 25 mm, the
3
minimum volume of the specimen, in cubic millimetres, shall be not less than 50D , where D is the nominal
maximum size of the coarse aggregate.
Normally, the entire specimen as received should be used for the determination of the density.
If the shape or size of a specimen is such that it is not possible to use all of it, a smaller specimen, conforming
to the requirements given above, may be sawn from the original.
4.4 Procedures
4.4.1 General
4.4.1.1 Calibration of the apparatus
The apparatus used shall be in calibration at time of use. The balance, the device for weighing specimens in
water and the oven should be calibrated at least once per year.
4.4.1.2 Determination of mass
This part of ISO 1920 permits three conditions under which the mass of a specimen can be determined:
a) as-received;
b) water-saturated;
c) oven-dried.
4.4.1.3 Determination of volume
This part of ISO 1920 permits three methods for determining the volume of the specimen:
a) by water displacement (reference method);
b) by calculation, using actual measurements;
c) for cubes, by calculation, using checked designated dimensions.
4.4.2 Mass of as-received specimen
Weigh the as-received specimen, to an accuracy of 0,1 % of the mass of the specimen.
Record the value, expressed in kilograms, as m .

ISO 1920-5:2004(E)
4.4.3 Mass of water-saturated specimen
Immerse the specimen in water at 20 °C ± 2 °C until the mass changes by less than 0,2 % in 24 h. Before
each weighing, wipe the surplus water from the surface using a moist cloth.
Specimens of normal-weight concrete cured in water continuously for at least 72 h prior to testing may be
assumed to satisfy this requirement.
Record the value, expressed in kilograms, of saturated mass as m .
s
4.4.4 Mass of oven-dried specimen
Dry the specimen in a ventilated oven at 105 °C ± 5 °C until the mass changes by less than 0,2 % in 24 h.
Before each weighing, cool the specimen to near room temperature in a dry airtight vessel or desiccator.
Record the value, expressed in kilograms, of the oven-dried mass as m .
o
4.4.5 Volume obtained by water displacement
4.4.5.1 General
This method is suitable for specimens of all shapes and is the only method suitable for specimens of irregular
shape.
The specimen shall be in a saturated condition.
This method is not suitable for specimens of no-fines concrete, concrete made with lightweight aggregate that
floats in water, concrete with large pores, or specimens the moisture content of which is not to be altered.
However, if an impermeable layer is applied to the specimen, this method may be used.
4.4.5.2 Mass in water
Allow the hydrostatic device of the balance to reach equilibrium. Ensure that the empty stirrup hanging from
the balance is completely immersed in the water tank and that the stirrup is not touching the bottom of the
tank.
Record the depth of the immersion of the stirrup and the apparent mass, in kilograms, of the stirrup as m .
st
Place the specimen in the stirrup and fully immerse in water to the same depth as the empty stirrup.
Take care to avoid trapping air bubbles on the sides of the sample and on the stirrup.
Weigh the completely immersed specimen and stirrup. Record (m + m ), the apparent mass, in kilograms.
st w
4.4.5.3 Mass in air
Remove the specimen from the stirrup, and wipe the surplus water from the surfaces using a damp cloth.
Weigh the specimen on the balance.
Record the mass, in kilograms, of the specimen in air as m .
a
4.4.5.4 Calculation of volume
Calculate the volume of the specimen using Equation (1):
