ANSI tile numbers split installation from the product spec
The Tile Council standards page fetched on 2026-10-11 groups American National Standards into families. A108 documents are installation methods. A118 documents are specifications for mortars, grouts, membranes, and related materials. A137 documents are specifications for the tile itself. Continuous maintenance, where the page uses that phrase, means the standard stays open for comment. The page's own timestamp on that fetch was 2026-09-10.
Installation examples from that list
A108.01, dated 2026 on the list, covers structures, substrates, and preparation. A108.02, dated 2023, covers workmanship. A108.10 covers grout in tilework. A108.17 covers crack-isolation membranes for thin-set tile and dimension stone. A108.19 covers interior gauged porcelain tiles and panels. Each of those is a method document, not a test of the tile body.
Material and tile examples
A118.1 specifies dry-set cement mortar. A118.10 specifies load-bearing bonded waterproof membranes. A118.12 specifies crack-isolation membranes. A118.20 specifies uncoupling membranes. A137.1 specifies ceramic tile, A137.2 specifies glass tile, and A137.3 specifies gauged porcelain tile and panels. The list names the document. It does not replace the purchased text, and this note does not invent requirements that the list did not print.
