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 soll.
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.

Foreword
This document (prEN 16301:2011) has been prepared by Technical Committee CEN/TC 246 “Natural stones”,
the secretariat of which is held by UNI.
This document is currently submitted to the CEN Enquiry.
1 Scope
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.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
ISO 1065, Non-ionic surface-active agents obtained from ethylene oxide and mixed non-ionic surface-active
agents -- Determination of cloud point
ISO 11664-2, Colorimetry -- Part 2: CIE standard illuminants
ISO 11998, Paints and varnishes – Determination of wet-scrub resistance and cleanability of coatings
3 Principle
A defined set of staining agents is applied on a defined stone surface. The mode of application is specified.
The specimens are conditioned and washed with a standardised washing machine. The stones are dried and
the possible remainders of the stains are assessed by a visual observation.
4 Definitions
Surface finishing: the final surface texture applied to a stone during processing.
Matt finished surface: surface treatment to produce a very flat, uniform, but no polished finish (e.g. by
means of a silicium carbide bonded polishing disk with grain size F 400 mesh).
Surface treatment: The term implies that a chemical has been used for the protection of the
surface by coating.
Impregnation: Protection of the surface of a stone by a pore-sealing product or a chemical
coating.
Staining agent: Liquid used to produce stains on the surface of the stone.
