DIN EN 12371:2010-07

The standard specifies a method to determine the effect of freeze/thaw cycles on natural stones. It contains methods for both a shorter technological test (test A) to determine the effect of freeze/thaw cycles on the relevant performance characteristics and an identification test (test B). The frost resistance of natural stones is determined by a test comprising cycles of freezing in air and thawing in water. DIN EN 1469, DIN EN 12057 and DIN EN 12058 refer to the test standard with regard to CE marking of natural stones. Therefore the standard addresses test laboratories but also natural stone producers carrying out factory production control. 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.
