(Test Method)Standard Test Method for Facial Dimensions and Thickness of Flat, Rectangular Ceramic Wall and Floor Tile
Standard Test Method for Facial Dimensions and Thickness of Flat, Rectangular Ceramic Wall and Floor Tile
SIGNIFICANCE AND USE
4.1 This test method provides a means of determining whether a lot of tile meets specifications of variations in size and thickness. In specifications, the nominal size always refers to the minor facial dimension and the nominal thickness of a tile always refers to the major thickness.
SCOPE
1.1 This test method covers the determination of the facial dimensions and thickness of flat, rectangular ceramic wall and floor tile. This test method covers tile as defined in Terminology C242.
1.2 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.
1.3 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.
1.4 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.

6. Test Specimens
6.1 At least ten tile specimens shall be selected at random from the lot to be tested. The same specimens may be used for the
determination of facial dimensions and thickness. Brush the specimens to remove all adhering particles of clay or sand.
7. Procedure
7.1 Major Facial Dimension—Measure the length of the tile to the nearest 0.001 in. (0.025 mm) across two pairs of opposite
lugs. Follow the same procedure for measuring the width of the tile. For tile whose lugs are not arranged opposite each other, it
may be necessary to use a jig to obtain the major facial dimensions. For square tile, average all four measurements and call the
result the average major dimension. For oblong tile, average the two
