This standard BS EN 12370:2020 - TC Tracked Changes. Natural stone test methods. Determination of resistance to salt crystallisation is classified in these ICS categories:

• 73.020 Mining and quarrying
• 91.100.15 Mineral materials and products

This document specifies a test method to assess the relative resistance of natural stones with an open porosity of greater than 5 %, measured in accordance with EN 1936, to damage caused by the crystallization of salts. The test is not necessary for low porosity stones.
