ANSI A137.1:2021 – American National Standards Specifications for Ceramic Tile is a crucial compliance document for the ceramic tile industry. An American National Standard developed by the Tile Council of North America (TCNA), ANSI A137.1:2021 covers specifications for ceramic tile, offering quality criteria and listing and defining different types, sizes, physical properties, and grading procedures.
ANSI A137.1:2021 covers some testing procedures for classification, but for the majority of destructive or non-destructive sample testing of ceramic tiles, different ASTM International standards are referenced for assessing properties. For example, to determine bond strength, ANSI A137.1:2021 calls for a method found in ASTM C482-20.
The ASTM International standards for ceramic tile testing referenced in ANSI A137.1:2021 include:
ASTM C370-12(2020): Standard Test Method for Moisture Expansion of Fired Whiteware Products
ASTM C372-94(2020): Standard Test Method for Linear Thermal Expansion of Porcelain Enamel and Glaze Frits and Fired Ceramic Whiteware Products by the Dilatometer Method
ASTM C373-18: Standard Test Methods for Determination of Water Absorption and Associated Properties by Vacuum Method for Pressed Ceramic Tiles and Glass Tiles and Boil Method for Extruded Ceramic Tiles and Non-tile Fired Ceramic Whiteware Products
