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 3.
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 part of ISO 2039 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 2039-1 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 2, Mechanical
properties.
This third edition cancels and replaces the second edition (ISO 2039-1:1993), subclause 8.3 and annex A of which
have been technically revised.
ISO 2039 consists of the following parts, under the general title Plastics — Determination of hardness:
 Part 1: Ball indentation method
 Part 2: Rockwell hardness
Annex A of this part of ISO 2039 is for information only.

INTERNATIONAL STANDARD ISO 2039-1:2001(E)

Plastics — Determination of hardness —
Part 1:
Ball indentation method
1 Scope
This part of ISO 2039 specifies a method for determining the hardness of plastics and ebonite by means of a
loaded ball indenter.
The ball indentation hardness determined by this method may provide data for research and development, quality
control and acceptance or rejection under specifications.
2 Normative reference
The following normative document contains provisions which, through reference in this text, constitute provisions of
this part of ISO 2039. For dated references, subsequent amendments to, or revisions of, any of these publications
do not apply. However, parties to agreements based on this part of ISO 2039 are encouraged to investigate the
possibility of applying the most recent edition of the normative document indicated below. For undated references,
the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of
currently valid International Standards.
ISO 291:1997, Plastics — Standard atmospheres for conditioning and testing
3 Term and definition
For the purposes of this part of ISO 2039, the following term and definition apply.
3.1
ball indentation hardness
HB
the quotient of the load on the ball indenter by the surface area of the impression caused by the ball indenter after
a specified time of load application
NOTE It is expressed in newtons per square millimetre.
4 Principle
The method consists of forcing a ball under a specified load into the surface of the test specimen. The depth of
impression is measured under load. The surface area of the impression is computed from its depth. The ball
indentation hardness is then calculated from the following relationship:
Ball indentation hardness = Applied load/Surface area of impression
ISO 2039-1:2001(E)
5 Apparatus
5.1 Hardness tester, consisting essentially of a frame with an adjustable platform fitted with a plate to support
the test specimen, an indenter with its associated fittings and a device for applying the load without impact.
The tester shall also be equipped with a device to measure the depth of penetration of the indenter over a range of
0,4 mm with an accuracy of ± 0,005 mm.
The frame shall not be deformed under the maximum load by more than 0,05 mm, the deformation being measured
along the main axis of the applied force.
The indenter shall be a hardened and polished steel ball. The ball shall not show any deformation or damage after
the test.
The diameter of the ball shall be (5,0 ± 0,05) mm.
5.2 Timing device, accurate to ± 0,1 s
6 Test specimens
Each test specimen shall be a smooth flat sheet or block of sufficient size to minimize edge effects on the test
result; for example 20 mm ¥ 20 mm. The surfaces of the test specimen shall be parallel. A thickness of 4 mm is
recommended.
The supported surface of the test specimen shall not show any deformation after testing.
NOTE 1 If test specimens with thicknesses less than 4 mm are to be tested, it is possible to stack several test specimens on
top of each other. However, hardness values obtained on stacked test specimens and on single test specimens of the same
thickness may be different.
NOTE 2 Although every effort should be made to ensure the parallelism of the specimen, there are some cases, especially
specimens injection-moulded from semi-crystalline thermoplastics, where it is difficult to obtain test specimens that are exactly
flat. If such slightly warped test specimens are used, part of the measured “depth of impression” will in fact correspond to the
distance travelled by the indenter in pressing the test specimen down on to the supporting plate. This
