Paints and varnishes - Determination of film hardness by pencil test (ISO 15184:2012)
ISO 15184:2012 specifies a method for determining the film hardness by pushing pencils of known hardness over the film.
The test can be performed on a single coating of a paint, varnish or related product, or on the upper layer of a multi-coat system.
This rapid test has not been found to be useful in comparing the pencil hardness of different coatings. It is more useful in providing relative ratings for a series of coated panels exhibiting significant differences in pencil hardness.
The method is applicable only to smooth surfaces.
Beschichtungsstoffe - Bestimmung der Härte von Beschichtungen durch Testen mit Bleistiften (ISO 15184:2012)
Diese Internationale Norm legt ein Verfahren zum Bestimmen der Schichthärte durch das Schieben von
Bleistiften mit vorgegebenen Härtegraden über die Beschichtung fest.
Die Prüfung kann auf einer einzelnen Schicht einer Beschichtung oder auf der obersten Schicht eines
Mehrschichtsystems durchgeführt werden.
Diese schnelle Prüfung wurde als nicht nützlich befunden, um die Härten verschiedener Beschichtungen
durch Testen mit Bleistiften zu vergleichen. Es ist eher nützlich, relative Bewertungen für eine Reihe von
beschichteten Platten zu liefern, die erhebliche Unterschiede in der Härte durch Testen mit Bleistiften
aufweisen.
Das Verfahren ist nur auf glatten Oberflächen anwendbar.
Peintures et vernis - Détermination de la dureté du feuil par l'essai de dureté crayon (ISO 15184:2012)
L'ISO 15184:2012 spécifie une méthode de détermination de la dureté d'un feuil de peinture en déplaçant à sa surface des crayons de dureté connue.
L'essai peut être réalisé sur un revêtement monocouche de peinture, vernis ou produit associé ou sur la couche supérieure d'un système multicouche.
L'intérêt de cet essai rapide ne réside pas dans la comparaison des duretés crayon de différents revêtements mais dans l'obtention du classement d'une série de panneaux revêtus dont les duretés crayon présentent des différences significatives.
La méthode s'applique seulement aux surfaces lisses.

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 15184 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 9,
General test methods for paints and varnishes.
This second edition cancels and replaces the first edition (ISO 15184:1998), which has been technically revised.
The main changes are:
a) the incorrect instruction in 9.5 in the previous edition (now 8.5) to push the test panel has been corrected
to an instruction to push the pencil;
b) the requirement in 9.5 in the previous edition (now 8.5) that the pencil move at 0,5 mm/s to 1 mm/s has
been replaced by a requirement that the speed simply be uniform;
c) the use of propelling/mechanical pencils is now permitted;
d) the supplementary test conditions (formerly Annex A) have been incorporated in the test report;
e) a new Annex A giving information on the applicability of the method has been added.

IMPORTANT — The electronic file of this document contains colours which are considered to be
useful for the correct understanding of the document. Users should therefore consider printing this
document using a colour printer.
1 Scope
This International Standard specifies a method for determining the film hardness by pushing pencils of known
hardness over the film.
The test can be performed on a single coating of a paint, varnish or related product, or on the upper layer of a
multi-coat system.
This rapid test has not been found to be useful in comparing the pencil hardness of different coatings. It is more
useful in providing relative ratings for a series of coated panels exhibiting significant differences in pencil hardness.
The method is applicable only to smooth surfaces.

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.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
pencil hardness
resistance of the surface of a paint film to marking, or the formation of some other defect, as a result of the
action of a pencil, with a lead of specified dimensions, shape and hardness, which is pushed across the surface
4 Principle
A pencil lead with a defined geometry is pushed over the paint surface at an angle of 45°, exerting a force of
7,5 N on the surface. The hardness of the pencil lead is increased in steps until the surface of the coating is
marked by visible defects. The test result is the highest hardness at which no marking occurs.
ISO 15184:2012(E)
5 Apparatus
5.1 Test instrument, consisting of a metal block fitted with two wheels, one on each side, as shown in
Figure 1. The wheels shall be made in such a way that they do not scratch the paint surface during testing. In
the middle of the metal block, there is a cylindrical hole, inclined at an angle of (45 ± 1)°, for the pencil.
With the help of a clamp, pencils can be fixed in the instrument so that they are always in the same position.
Mounted on the top of the instrument is a level which is used to ensure that the test is carried out with the
instrument horizontal.
The instrument shall be designed so that, with the instrument in the horizontal position, the tip of the pencil
exerts a force of (7,5 ± 0,1) N on the paint surface.
Other types of test instrument may also be used, provided they give similar relative rating results.
5.2 Set of wooden drawing pencils, of the following hardnesses (see note):
9B - 8B - 7B - 6B - 5B - 4B - 3B - 2B - B - HB - F - H - 2H - 3H - 4H - 5H - 6H - 7H - 8H - 9H
Softer Harder
B - black HB - hard black F - firm H - hard
Pencils made by various manufacturers may be used by agreement between the interested parties, provided
they give similar relative rating results.
