Paints and varnishes - Rapid-deformation (impact resistance) tests - Part 2: Falling-weight test, small-area indenter (ISO 6272-2:2002)
This part of ISO 6272 describes a method for rapidly deforming, by impact with a spherical indenter of diameter 12,7 mm or 15,9 mm, a coating film and its substrate and evaluating the effect of such deformation. This test method should be restricted to testing in only one laboratory when numerical values are used because of the poor reproducibility of the method. Interlaboratory agreement is improved when ranking is used in place of numerical values.
Beschichtungsstoffe - Bestimmung der Widerstandsfähigkeit bei schlagartiger Verformung (Schlagfestigkeit) - Teil 2: Prüfung durch fallendes Gewichtsstück, kleine Prüffläche (ISO 6272-2:2002)
Dieser Teil von ISO 6272 beschreibt ein Verfahren zum schlagartigen Verformen einer Beschichtung und
deren Substrat mit einem kugelförmigen Eindringkörper von 12,7 mm oder 15,9 mm Durchmesser und zum
Bewerten der Auswirkung einer solchen Verformung.
ANMERKUNG Der Ausdruck „Schlagfestigkeit“ wird zwar im Titel und im Text dieses Teils von ISO 6272 benutzt, ein
wichtiges Merkmal des angewendeten Prüfgerätes ist aber, dass es eher eine schnelle Verformung hervorrufen sollte als
einen wirklichen Schlag.
Wenn Zahlenwerte verwendet werden, sollte dieses Prüfverfahren wegen der schlechten Vergleichbarkeit auf
Prüfungen in nur einem Laboratorium beschränkt werden. Die Übereinstimmung zwischen unterschiedlichen
Laboratorien wird verbessert, wenn anstelle von Zahlenwerten Rangstufen verwendet werden.

L'ISO 6272-2:2002 décrit une méthode visant à déformer rapidement, au moyen d'un choc avec un pénétrateur sphérique d'un diamètre de 12,7 mm ou de 15,9 mm, un revêtement ainsi que son substrat et à évaluer les effets d'une telle déformation.

ISO 6272-2:2002(E)
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 ISO6272-2 was prepared by Technical Committee ISO/TC35, Paints and varnishes,
Subcommittee SC 9, General test methods for paints and varnishes.
Together with ISO 6272-1, 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.

WARNING — This part of ISO 6272 does not purport to address 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 rapidly deforming, by impact with a spherical indenter of diameter
12,7 mm 15,9 mm
or , a coating film and its substrate and evaluating the effect of such deformation.
NOTE The term “impact resistance” is included in the title and text 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.
This test method should be restricted to testing in only on
