ISO/AWI 25146

Determination of the chemical resistance for engineered stones with resin or cement binders or a combination of the two, intended for use in countertops and vanities (furniture in general), in floor and wall coverings, for interior and exterior (constructions in general)

Scope

This standard specifies a test method for evaluating the chemical resistance of engineered stones with a polished surface when exposed to chemical substances over an extended period of time at room temperature. It applies to all engineered stones, but it's important to note that those containing calcium carbonate aggregates are susceptible to acid damage.
