A 2 cm porcelain paver standard is about unbonded strength
On April 5, 2022 the Tile Council announced that the ANSI ASC A108 committee had approved a standard characterizing 2 cm gauged porcelain tile pavers. The press note says those pavers are often used in unbonded or raised flooring, so the committee gave particular attention to strength and impact criteria. The criteria came from a multi-year consensus process and from work in the Tile Council product-performance laboratory.
What the announcement does not print
The fetched announcement says standardized performance criteria were needed for specifiers, installers, owners, and consumers. It does not print the numeric test limits in the paragraphs retrieved on 2026-10-11. This note does not invent those limits, and it does not treat a 2 cm thickness as proof that a paver is frost resistant.
A different question from absorption
Porcelain as a body is defined elsewhere by water absorption. This announcement is about a thick paver format used where the tile is not bonded the way a thin interior floor is. Those are separate specifications.
