Natural stone test methods - Determination of sensitivity to accidental staining

Le présent document spécifie une méthode permettant d'évaluer la sensibilité des pierres naturelles au tachage accidentel. Il 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.
