ASTM C648 – Standard Test Method for Breaking Strength of Ceramic Tile
Description:
Significance and Use
5.1 The test method provides means for establishing whether or not a lot of ceramic tile meets the strength requirements which may appear in tile specifications. Tile strength is the force in pounds-force (or newtons), as read from the pressure gage, necessary to cause the tile to break.
Scope
1.1 This test method covers the determination of the breaking strength of ceramic tile, ceramic mosaic tile, quarry tile, porcelain tile and paver tile, having a facial area of at least 1 in.2 (6.4 cm2). Tiles may be glazed or unglazed.
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.
