Natural stone test methods - Determination of sensitivity to accidental staining
The European Standard specifies a method to assess the sensitivity of natural stones when exposed to accidental staining. It defines a procedure for the application of the stains, the cleaning and the assessment of the surface appearance after cleaning. It also covers the possibility to assess the efficiency of a surface treatment. Note that the method does not intend to present any de-staining technique.
Prüfverfahren für Naturstein - Bestimmung der Empfindlichkeit gegen unbeabsichtigte Fleckenbildung
Diese Europäische Norm legt ein Verfahren zur Bewertung der Empfindlichkeit von Natursteinen fest, die ungewollter Fleckenbildung ausgesetzt sind. Sie legt ein Verfahren zum Aufbringen der Flecken, zur Reinigung und zur Bewertung der Oberflächenbeschaffenheit nach dem Reinigen fest. Sie behandelt außerdem auch die Möglichkeit einer Bewertung der Wirksamkeit einer Oberflächenbehandlung. Es ist zu beachten, dass mit dem behandelten Verfahren keine Technik zur Fleckentfernung angeboten werden sollte.
Méthodes d'essai pour les pierres naturelles - Détermination de la sensibilité au tachage accidentel
La présente norme européenne spécifie une méthode permettant d’évaluer la sensibilité des pierres naturelles au tachage accidentel. Elle définit un mode opératoire à suivre pour l’application des taches, le nettoyage et l’évaluation de l’aspect de la surface après nettoyage, et permet également d’évaluer l’efficacité d’un traitement de surface. Il est à noter que cette méthode ne préconise en aucun cas une technique particulière de détachage.
Preskusne metode za naravne kamne - Ugotavljanje občutljivosti za naključno obarvanje
Ta evropski standard določa metodo za ocenjevanje občutljivosti naravnih kamnov, ko so izpostavljeni naključnemu obarvanju. Določa postopek nanosa madežev, čiščenja in ocenjevanja videza površine po čiščenju. Vključuje tudi možnost ocenjevanja učinkovitosti površinske obdelave. Namen metode ni predstavitev načinov odstranjevanja madežev.
