ASTM C1243-23

Standard Test Method for Relative Resistance to Deep Abrasive Wear of Unglazed Ceramic Tile by Rotating Disc

SIGNIFICANCE AND USE
4.1 This test method provides the means to measure the potential resistance to wear of unglazed ceramic tile intended for floor coverings. This test method does not consider physical appearance but is intended to measure durability. See Test Method C1027 for the determination of visible abrasion resistance of glazed ceramic tile.  
4.1.1 See Test Method C501 for an alternative method to determine deep abrasion.
SCOPE
1.1 This test method covers the deep abrasive wear by measuring the loss of volume resulting from abrasion of unglazed ceramic tile under given conditions by means of a rotating disc and the use of abrasive material.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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.
