ASTM C1243-93(2015)e1
(Test Method)Standard Test Method for Relative Resistance to Deep Abrasive Wear of Unglazed Ceramic Tile by Rotating Disc
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 and health practices and determine the applicability of regulatory limitations prior to use.

5. Apparatus
5.1 Abrasion apparatus (see Fig. 1) consisting essentially of a rotating disc, a storage hopper with a dispensing device for the
abrasive material, a test specimen support, and a counterweight. The disc is made of Fe 360A steel (ISO 630-1980) with a diameter
of 200 6 0.2 mm and thickness at the edge of 10 6 0.1 mm, and with a rate of revolution of 75 r/min. The pressure with which
test specimens are held against the steel disc is determined by calibrating the apparatus against float glass (bathside). The pressure
is adjusted such that, after 150 revolutions, a chord of 24 6 0.5 mm is produced.
NOTE 1—For the specification of float glass, see Test Method C448, Table A1.4.
