Natural stone test methods - Determination of frost resistance

Scope

This European Standard specifies a method to assess the effect of freeze/thaw cycles on natural stones (see EN 12670 for terminology, and EN 12440 for denomination). The standard contains provision for both a shorter technological test (Test A) to assess the effect of freeze/thaw cycles on the relevant performance characteristics and an identification test (Test B).
NOTE Some marbles, as defined in EN 12440, undergo changes in physical properties as a result of the test conditions rather than the freeze/thaw cycles. In these cases, additional tests (for example EN 14066) should be applied.

Directives and Regulations

When the standard is harmonized under a directive or regulation, the word Harmonized appear. When such an inscription does not appear, it means that the standard is related to / supporting the relevant directive or regulation.
