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
Dieses Dokument legt ein Verfahren zur Bewertung der Empfindlichkeit von Natursteinen fest, die ungewollter Fleckenbildung ausgesetzt sind. Es legt ein Verfahren zum Aufbringen der Flecken sowie zur Reinigung und zur Bewertung der Oberflächenbeschaffenheit nach dem Reinigen fest. Es 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 soll.
Méthodes d'essai pour pierres naturelles - Détermination de la sensibilité au tachage accidentel
Le présent document spécifie une méthode permettant d'évaluer la sensibilité des pierres naturelles au tachage accidentel. Il définit un mode opératoire d'application des taches, de nettoyage et d’évaluation de l'aspect de surface après nettoyage et permet également d'évaluer l'efficacité d'un traitement de surface. Il est à noter que cette méthode ne propose en aucun cas une technique particulière de détachage.
