ASTM C1243-93(2015)e1

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.

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 and health practices and determine the applicability of regulatory limitations prior to use.
