Stonelam (powered by Laminam) a leading name in the industry, presented its unglazed porcelain slab for water absorption tests. SASO has produced the standard SASO ISO 10545-3:2018 which provides tight controls over how the water absorption capacities of porcelain slabs are to be determined. Such rates impact the suitability of the different slabs, in particular, to be used in applications mostly facing moist exposure.
