Which standard outlines criteria for tile performance and related products?

The standard that outlines criteria for tile performance and related products is ANSI A137.1. This standard specifically focuses on the classification, requirements, and test methods for various types of ceramic tiles, ensuring that they meet certain performance expectations in terms of durability, water absorption, strength, and various other characteristics. By detailing these parameters, ANSI A137.1 provides guidelines for manufacturers and helps consumers make informed decisions about the quality of tile products.

Other standards mentioned serve different purposes. For example, ANSI A118.6 is focused on the specifications for modified dry-set cement mortar, which plays a role in tile installation but does not cover tile performance itself. ANSI A108 contains installation standards for ceramic tiles, providing guidelines on how to properly install tile products rather than the performance criteria of the tiles themselves. ANSI A136.1 addresses the definitions of the various types of adhesives used in conjunction with tiling but is not centered on tile performance. Each of these standards plays an essential role in the broader context of tiling, but ANSI A137.1 is specifically dedicated to the performance aspects of the tile themselves.
