Natural stone test methods - Determination of sensitivity to accidental staining

This document 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 as well as the cleaning and the assessment of the surface appearance after cleaning. It also covers the possibility to assess the efficiency of a chemical 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 chemischen Behandlung.
Es ist zu beachten, dass mit dem behandelten Verfahren keine Technik zur Fleckentfernung angeboten werden soll.
