1.1 This test method covers procedures for measuring impact properties of ceramic tile, bonded to a standardized concrete substrate, from a falling 2-in. steel ball.

1.2 This test method is intended solely for evaluating standardized laboratory test specimens and does not purport to simulate actual installed performance.

1.3 Units—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.

1.4 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.

1.5 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.

4.1 Impact diameter may be used to interpret impact resistance.

4.2 Maximum impact diameter may be a specified requirement for tile.
