EN ISO 6272-2:2011

Paints and varnishes - Rapid-deformation (impact resistance) tests - Part 2: Falling-weight test, small-area indenter (ISO 6272-2:2011)

ISO 6272-2:2011 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, dropped under standard conditions, acting on a small-area spherical indenter.
NOTE          The terms "impact" and "impact resistance" are used in the title and text of ISO 6272-2, but an important characteristic of the apparatus used is that it should produce rapid deformation rather than a true impact.
Because of the poor reproducibility of this test method, the method should be restricted to testing in only one laboratory when the results are expressed as numerical values. Interlaboratory agreement is improved when ranking is used in place of numerical values.

Beschichtungsstoffe - Prüfung der Widerstandsfähigkeit bei schlagartiger Verformung (Schlagfestigkeit) - Teil 2: Prüfung durch fallendes Gewichtsstück, kleine Prüffläche (ISO 6272-2:2011)

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 verformt wird.
ANMERKUNG Die Ausdrücke „Schlag“ und „Schlagfestigkeit“ wurden zwar in den Titel und Text 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".
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.

Peintures et vernis - Essais de déformation rapide (résistance au choc) - Partie 2: Essai de chute d'une masse avec pénétrateur de surface réduite (ISO 6272-2:2011)

L'ISO 6272-2:2011 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, lâchée dans des conditions normalisées, agissant sur un pénétrateur sphérique de surface réduite.
En raison de sa faible reproductibilité, lorsque les résultats sont exprimés sous forme de valeurs numériques, la présente méthode est destinée à être utilisée pour des essais effectués dans un même laboratoire. La concordance interlaboratoires est améliorée lorsqu'un classement est utilisé à la place de valeurs numériques.

Barve in laki - Preskusi na podlagi hitre deformacije (odpornost proti udarcu) - 2. del: Metoda s padajočo utežjo, majhna površina vtiska (ISO 6272-2:2011)

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, spuščena v standardnih pogojih, ki deluje z majhno površino vtiska.
