Paints and varnishes - Rapid-deformation (impact resistance) tests - Part 1: Falling-weight test, large-area indenter (ISO 6272-1:2002)
ISO 6272-1:2002 describes a method for evaluating the resistance of a dry film of paint, varnish or related product to cracking or peeling from a substrate when it is subjected to a deformation caused by a falling weight, with a 20-mm-diameter spherical indenter, dropped under standard conditions.
The method described can be applied
either as a pass/fail test, the test being carried out from one drop height and with a specified mass, so as to test compliance with a particular specification;or as a classification test, to determine the minimum mass and/or drop height for which the coating cracks or peels from its substrate by gradually increasing the drop height and/or the mass.

L'ISO 6272 décrit une méthode permettant d'évaluer la résistance d'un feuil sec de peinture, vernis ou produit assimilé au craquelage ou au décollement de son subjectile lorsque celui-ci est soumis à une déformation provoquée par une masse tombante avec un pénétrateur sphérique de 20 mm de diamètre, lâchée dans des conditions normalisées.
La méthode est applicable
soit en essai tout ou rien, l'essai étant réalisé avec une hauteur de chute et une masse données afin de vérifier la conformité à une spécification particulière,soit en essai de classement, afin de déterminer la masse minimale et/ou la hauteur de chute pour lesquelles le revêtement se craquelle ou se décolle de son subjectile, l'essai étant réalisé en augmentant progressivement la hauteur de chute et/ou la masse.

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.
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 6272 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO6272-1 was prepared by Technical Committee ISO/TC35, Paints and varnishes,
Subcommittee SC 9, General test methods for paints and varnishes.
Together with ISO 6272-2, this part of ISO 6272 cancels and replaces ISO 6272:1993. The main change is the
introduction of the option to increase the mass of the weight that is dropped onto the panel, thus enabling a more
severe test to be carried out.
ISO 6272 consists of the following parts, under the general title Paints and varnishes — Rapid-deformation (impact
resistance) tests:
— Part 1: Falling-weight test, large-area indenter
— Part 2: Falling-weight test, small-area indenter
Annex A forms a normative part of this part of ISO 6272.

INTERNATIONAL STANDARD ISO 6272-1:2002(E)
Paints and varnishes — Rapid-deformation (impact resistance)
tests —
Part 1:
Falling-weight test, large-area indenter
WARNING — This part of ISO 6272 does not purport to address the all of the safety problems, if any,
associated with its use. It is the responsibility of the user of this part of ISO 6272 to establish appropriate
safety and health practices and determine the applicability of regulatory limitations prior to use.
1 Scope
This part of ISO 6272 describes a method for evaluating the resistance of a dry film of paint, varnish or related
product to cracking or peeling from a substrate when it is subjected to a deformation caused by a falling weight, with
a 20-mm-diameter spherical indenter, dropped under standard conditions.
NOTE The term “impact resistance” is included in the title of this part of ISO 6272, but one important characteristic of the
apparatus used is that it should produce rapid deformation rather than a true impact.
The method described can be applied
— either as a pass/fail test, the test being carried out from one drop height and with a specified mass, so as to test
compliance with a particular specification;
— or as a classification test, to determine the minimum mass and/or drop height for which the coating cracks or
peels from its substrate by gradually increasing the drop height and/or the mass.
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of
this part of ISO 6272. 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 6272 are encouraged to investigate the
possibility of applying the most recent editions of the normative documents 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.

4 Apparatus
Ordinary laboratory apparatus and glassware, together with the following:
4.1 Falling-weight apparatus, comprising the elements described in 4.1.1 to 4.1.7.
4.1.1 Base stand, of sufficient mass to support the die (4.1.5).
4.1.2 Primary falling weight (see Figure 1), the head having the shape of a spherical segment of diameter
(20± 0,3) mm, and a total mass of (1 000± 1) g.
4.1.3 Secondary weight(s), which may be added to the primary falling weight in order to increase the severity of
the test. The mass of each weight may be (1 000± 1) g or (2 000± 2) g, and the total load may be 1 kg, 2 kg, 3 kg
or .4kg
4.1.4 Vertical guide tube (see Figures 1 and 2), to direct the primary falling weight (4.1.2) perpendicularly on to the
test panel. Th
