BS EN 12371:2010

This standard BS EN 12371:2010 Natural stone test methods. Determination of frost resistance is classified in these ICS categories:

• 73.020 Mining and quarrying
• 91.100.15 Mineral materials and products

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.
