Natural stone test methods - Determination of sensitivity to changes in appearance produced by thermal cycles; German version EN 16140:2011
Prüfverfahren für Naturwerkstein - Bestimmung der Empfindlichkeit gegen Änderungen des äußeren Erscheinungsbildes durch thermische Zyklen; Deutsche Fassung EN 16140:2011
Overview
This test 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). The specimens are subjected to successive cycles, each formed by drying at specified temperatures followed by immediate immersion in water at specified temperatures. This standard is directed at manufacturers and distributors of natural stones and independent test laboratories. The Committee responsible for this standard is NA 062-03-11 GA "Gemeinschaftsarbeitsausschuss NMP/NABau: Naturwerkstein; Anforderungen, Prüfverfahren und Terminologie" ("Joint Working Committee NMP/NABau: Natural stone; requirements, test methods and terminology") at DIN.
