ASTM C704/C704M-09e1

This test method measures the relative abrasion resistance of various refractory samples under standard conditions at room temperature.

The abrasion resistance of a refractory material provides an indication of its suitability for service in abrasion or erosive environments.

The results obtained by this test method could be different than those obtained in service because of the different conditions encountered.

1.1 This test method covers the determination of relative abrasion resistance of refractory brick at room temperature. This test method can also be applied to castable refractories (see Metric Dimensions, Practice C 861 and Practice C 865) and plastic refractories (see Practice C 1054).

1.2 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the 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.
