Paints and varnishes - Rapid-deformation (impact resistance) tests - Part 1: Falling-weight test, large-area indenter (ISO 6272-1:2011)
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.
Beschichtungsstoffe - Prüfung der Widerstandsfähigkeit bei schlagartiger Verformung (Schlagprüfung) - Teil 1: Prüfung durch fallendes Gewischtsstück, große Prüffläche (ISO 6272-1:2011)
Dieser Teil von ISO 6272 legt ein Prüfverfahren zum Bewerten des Widerstandes einer Beschichtung aus
einem Beschichtungsstoff gegen Rissbildung oder Ablösen von einem Substrat fest, wenn die Beschichtung
unter Normbedingungen durch einen fallenden Körper mit 20 mm Durchmesser verformt wird.
ANMERKUNG Der Ausdruck „Schlagprüfung“ wurde zwar in den Titel dieses Teiles von ISO 6272 aufgenommen, aber
eines der bestimmenden Merkmale des verwendeten Gerätes ist, dass es eine schnelle Verformung als Folge der Schlageinwirkung
hervorruft, aber keinen „Schlag“.
Das hier beschriebene Prüfverfahren kann angewendet werden
- entweder als Ja/Nein-Prüfung mit einer festgelegten Fallhöhe und Masse, um die Übereinstimmung mit
einer bestimmten Spezifikation zu prüfen; oder
- als Einstufungstest zum Bestimmen der Mindestmasse und/oder Mindestfallhöhe, bei der die Beschichtung
zu reißen oder sich abzulösen beginnt, durch stufenweises Erhöhen der Masse und/oder Fallhöhe.
Peintures et vernis - Essais de déformation rapide (résistance au choc) - Partie 1: Essai de chute d'une masse avec pénétrateur de surface importante (ISO 6272-1:2011)
L'ISO 6272-1:2011 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 lorsqu'il est soumis à une déformation provoquée par la chute d'une masse comportant 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, l'essai étant réalisé en augmentant progressivement la hauteur de chute et/ou la masse, afin de déterminer la masse et/ou la hauteur de chute minimales pour lesquelles le revêtement se craquelle ou se décolle de son subjectile.
Barve in laki - Preskusi na podlagi hitre deformacije (odpornost proti udarcu) - 1. del: Metoda s padajočo utežjo, velika površina vtiska (ISO 6272-1:2011)
Ta del ISO 6272 opisuje metodo za vrednotenje odpornosti suhega filma barve, laka ali sorodnega izdelka proti pokanju ali luščenju s substrata, ko je izpostavljen deformaciji, ki jo povzroči padajoča utež z 20-mm kroglastim vtiskom, spuščena v standardnih pogojih.

ISO 6272-1:2011(E) iv © ISO 2011 – All rights reserved 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 6272-1 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 6272-1:2002), which has been technically revised. The main technical changes are as follows: a) in the description of the guide tube (see 4.1.3) and in Figure 1, the play permitted between the guide tube and the falling weight has been changed; b) a “principle” clause has been added; c) the test is no longer carried out at a specified relative humidity; instead, the relative humidity is simply recorded but the test has to be completed within a specified length of time after conditioning the test panels; d) the supplementary test conditions (formerly Annex A) have been incorporated in the test report. 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

INTERNATIONAL STANDARD ISO 6272-1:2011(E) © ISO 2011 – All rights reserved 1 Paints and varnishes — Rapid-deformation (impact resistance) tests — Part 1: Falling-weight test, large-area indenter 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 terms “impact” and “impact resistance” are used in the title and text of this part of ISO 6272, but an 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, by gradually increasing the drop height and/or the mass, the minimum mass and/or drop height for which the coating cracks or peels from its substrate. 2 Normative references The following referenced documents are indispensable for the application of this document.
