Report (Ref. 28472/2023) examines the weathering resistance of “Orient White” natural stone per ÖNORM EN 12372 and 12371 standards. We tested 30 prisms sized 50 x 40 x 240 mm for bending and frost resistance.
Delivered on June 13, 2023, the testing ran from June 13 to July 19, 2023. We specifically assessed frost resistance, using ten 50 x 40 x 240 mm prism samples, and conducted 56 freeze-thaw cycles between June 15 and July 13, 2023, with two cycles daily.
On July 19, 2023, we evaluated bending strength using a Mohr & Federhaff Universal Testing Machine. Results showed a 19.98% strength reduction post-frost test, within the 20% ÖNORM B 3108:2014 limit.
In conclusion, “Snow White” proved its frost resistance.
