# ASTM C648

Standard Test Method for Breaking Strength of Ceramic Tile

[Back to all techniques](/analytical-techniques/)

## 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.
