ISO/FDIS 25146

This document specifies a test method for determining the chemical resistance of engineered stone with resin and cement binders or combinations used in countertops and vanities (furniture in general), floor and wall coverings, and interior and exterior (constructions in general).

To find any change in colour and appearance, two tests are specified for determining the chemical durability of engineered stones at normal room temperature. The tests are appropriate for all varieties of engineered stones that possess a polished surface and may come into contact with chemical substances for an extended period of time.
