ASTM C485
1. Scope
1.1 This test method covers procedures for measuring diagonal and edge warpages of the following categories of ceramic tile:
1.1.1 Square Tile 2 by 2 in. (51 by 51 mm) or larger, that are nominally flat, of uniform overall thickness, and have a smooth face of one of the types: unglazed, bright glazed, matte glazed, or finely crystalline glazed.
1.1.2 Oblong Tile no facial dimension smaller than 2 in. (51 mm), that are flat, of uniform overall thickness, and have a smooth face of one of the types: unglazed, bright glazed, matte glazed, or finely crystalline glazed.
1.1.3 Square and Oblong Tileno facial dimension smaller than 2 in. (51 mm), that are flat, but have an irregular face such as embossed, sloped, bumpy, wavy, coarsely crystalline, or wire-cut textured.
1.1.4 Nonrectilinear Tilelarger than 4 in. 2 (26 cm 2 ), that are flat and of uniform body thickness with smooth or irregular face, such as hexagonal, diamond, Spanish type, and so forth.
1.1.5 Trim Tilemeeting one of the descriptions in except that only a part of the tile surface is flat. (Surface trim tile should be treated as flat tile whenever possible.)
1.1.6 Square or Oblong Tilewith facial area less than 4 in. 2 (26 cm 2 ) and at least two straight sides equal to or greater than 1.0 in. (25 mm) long. (Modular 1- by 1-in. tile are not in the scope of this test method.)
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 the inch-pound units are to be regarded as the standard. The SI (metric) units given in parentheses are for information only.
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 and health practices and determine the applicability of regulatory limitations prior to use.
