Standard Test Method for  Measuring Warpage of Ceramic Tile

ASTM - ASTM International

ASTM C485-24

Organization:

Year: 2024

Abstract: 5.1 This test method provides a means for determining whether or not a lot of ceramic tile meets the warpage requirements that may appear in specifications to assure satisfactory tile installations. In accordance with this test method, warpage is calculated as a percentage of the length of the edge or diagonal being tested. It is realized that the percentage values based on the overall edge length, or on the overall diagonal length of a tile will be slightly lower than those based on the distance between reference points. However, the ratio of the overall lengths to the distance between reference points will be practically constant for any particular size of tile and, therefore, the percentage values will be comparable and equally indicative of warpage.

scope	1.1 This test method covers procedures for measuring the corner, diagonal, and edge warpages of ceramic tile. 1.1.1 Tile Requirements for Corner, Diagonal, and Edge Warpage Measurement Tile should be nominally flat, uniform in overall thickness, smooth faced, and rectangular in shape, including square. 1.1.2 Tile Requirements for Corner Warpage Measurement All facial edge dimensions equal to or greater than 2.36 in. (60 mm) in length. 1.1.3 Tile Requirements for Edge and Diagonal Warpage Measurement All facial edge dimensions equal to or greater than 2 in. (51 mm) in length. 1.1.4 Trim Tile meeting the descriptions in 1.1.1 – 1.1.3 except that only a part of the tile surface is flat. (Surface trim tile should be treated as flat tile whenever possible.) 1.2 This test method is not applicable to tile having embossed surfaces that are not flat, or that have a combination of variable body thickness and an irregular face. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
