(Test Method)Standard Test Method for Bond Strength of Ceramic Tile to Portland Cement Paste
Standard Test Method for Bond Strength of Ceramic Tile to Portland Cement Paste
SIGNIFICANCE AND USE
5.1 This test method provides a means of determining whether or not tile of the types indicated in 1.1 can be bonded with adequate strength to portland cement paste. Tile specifications can refer to this test method in order to establish minimum bond strength limits appropriate to the service conditions that are anticipated.
5.2 Separation between bond coat and setting bed, or breakage of the setting bed itself shall not be considered failures of tile bond.
SCOPE
1.1 This test method covers the determination of the ability of ceramic tile, ceramic mosaic tile, quarry tile, porcelain tile, and paver tile to be bonded to portland cement paste. Tiles may be glazed or unglazed. This test method includes both face-mounted and back-mounted tile.
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.

3. Terminology
3.1 Definitions:
3.1.1 For definitions of the types of tile listed in 1.1, refer to Terminology C242.
4. Summary of Test Method
4.1 This test method consists of bonding tile under controlled conditions to a pure portland cement paste bond coat, supported
by a cement mortar bed.
4.2 After proper cure of the test assembly, a load is applied to one edge of the tile and the load increased at a definite rate until
the bond between tile and bond coat is broken.
4.3 Because the laboratory method of applying shear stress rapidly loads both tile and setting bed in compression, a stronger
than normal setting bed for the test specimens is specified. This avoids failure of the setting bed before the desired failure at the
tile-bond coat interface occurs. In real tile installations with portland cement paste an entirely different loading mechanism, usually
generated primarily by shrinking of the setting bed or structural backing, results in mild tension in setting bed and mild
compression in the tile, but the same type of shear stress occurs between tile and bond coat as does in response to the laboratory
loading method. The finding of an adequate bond strength under the conditions of this test method can be taken as proof that the
tested tile could be permanently bonded in a properly installed conventional installation using the lean, low-shrinkage mortars
customarily specified for this particular purpose.
