ANSI A137.1:2019 – 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 A137.1:2019 covers specifications for ceramic tile, offering quality criteria and listing and defining different types, sizes, physical properties, and grading procedures. ANSI A137.1:2019 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 A137.1:2019 calls for a method found in ASTM C482-02(2014).
ASTM International standards for ceramic tile testing referenced in ANSI A137.1:2019 include: ASTM C370-12(2020): Standard Test Method for Moisture Expansion of Fired Whiteware Products ASTM C372-94(2016): 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 ASTM C424-93(2016): Standard Test Method for Crazing Resistance of Fired Glazed Whitewares by Autoclave Treatment ASTM C482-20: Standard Test Method for Bond Strength of Ceramic Tile to Portland Cement Paste ASTM C484-20: Standard Test Method for Thermal Shock Resistance of Glazed Ceramic Tile ASTM C485-16: Standard Test Method for Measuring Warpage of Ceramic Tile ASTM C499-20: Standard Test Method for Facial Dimensions and Thickness of Flat, Rectangular Ceramic Wall and Floor Tile ASTM C502-16: Standard Test Method for Wedging of Flat, Rectangular Ceramic Wall and Floor Tile ASTM C609-20: Standard Test Method for Measurement of Light Reflectance Value and Small Color Differences Between Pieces of Ceramic Tile ASTM C648-04(2014): Standard Test Method for Breaking Strength of Ceramic Tile ASTM C650-04(2019): Standard Test Method for Resistance of Ceramic Tile to Chemical Substances ASTM C1026-13(2018): Standard Test Method for Measuring the Resistance of Ceramic and Glass Tile to Freeze-Thaw Cycling ASTM C1027-19: Standard Test Method for Determining Visible Abrasion Resistance of Glazed Ceramic Tile ASTM C1243-93(2015)e2: Standard Test Method for Relative Resistance to Deep Abrasive Wear of Unglazed Ceramic Tile by Rotating Disc ASTM C1378-04(2019): Standard Test Method for Determination of Resistance to Staining
