Natural stone test methods - Determination of sensitivity to changes in appearance produced by thermal cycles
This European Standard specifies a method to assess possible alterations of natural stones (mainly visible sensitivity to oxidation processes) under the effect of sudden changes in temperature (thermal shock).
Prüfverfahren für Naturwerkstein - Bestimmung der Empfindlichkeit gegen Änderungen des äußeren Erscheinungsbildes durch thermische Zyklen
Diese Europäische Norm legt ein Verfahren zur Bewertung möglicher Verwitterungen von Natursteinen (vorwiegend sichtbare Empfindlichkeit auf Oxidationsprozesse) unter der Einwirkung plötzlicher Temperaturwechsel (thermischer Schock) fest.
Méthodes d'essai pour pierres naturelles - Détermination de la sensibilité aux changements d'aspect induits par des cycles thermiques
La présente Norme européenne décrit une méthode permettant d’évaluer les modifications possibles des pierres naturelles (sensibilité aux procédés d’oxydation généralement visible) sous l’effet de changements brusques de température (choc thermique).
Preskušanje naravnega kamna - Ugotavljanje občutljivosti pri spremembi videza, nastalega pri termičnih ciklih
Ta evropski standard določa metodo za ocenjevanje morebitnih sprememb naravnega kamna (predvsem vidne občutljivosti na oksidacijske procese) zaradi nenadnih sprememb temperature (temperaturni šok).

EN 16140:2019 (E) 3 European foreword This document (EN 16140:2019) has been prepared by Technical Committee CEN/TC 246 “Natural stones”, the secretariat of which is held by UNI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by July 2019, and conflicting national standards shall be withdrawn at the latest by July 2019. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document will supersede EN 16140:2011. In comparison with the previous edition, the changes concern essentially the interpretation of the modification of aspect after the thermal cycles. In Annex A, the figures are completed and clarified. This European Standard is one of the series of standards for tests on natural stone. Test methods for natural stone consist of the following standards: — EN 1925, Natural stone test methods — Determination of water absorption coefficient by capillarity; — EN 1926, Natural stone test methods — Determination of uniaxial compressive strength; — EN 1936, Natural stone test methods — Determination of real density and apparent density, and of total and open porosity; — EN 12370, Natural stone test methods — Determination of resistance to salt crystallization; — EN 12371, Natural stone test methods — Determination of frost resistance; — EN 12372, Natural stone test methods — Determination of flexural strength under concentrated load; — EN 12407, Natural stone test methods — Petrographic examination; — EN 12440, Natural stone — Denomination criteria; — EN 12670, Natural stone — Terminology; — EN 13161, Natural stone test methods — Determination of flexural strength under constant moment; — EN 13364, Natural stone test methods — Determination of the breaking load at dowel hole; — EN 13373, Natural stone test methods — Determination of geometric characteristics on units; — EN 13755, Natural stone test methods — Determination of water absorption at atmospheric pressure; — EN 14066, Natural stone test methods — Determination of resistance to ageing by thermal shock; — EN 14146, Natural stone test methods — Determination of the dynamic modulus of elasticity (by measuring the fundamental resonance frequency); SIST EN 16140:2019
