1.1 This practice shows the behavior of carbon refractories when subjected to the action of an alkali at an elevated temperature. This destructive condition as encountered in service is accelerated in the test to show in a short time the probable behavior of the carbon refractory during use.

1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information only.

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.


The disintegration of carbon refractories by alkali attack at elevated temperatures is an important consideration in using these materials for certain applications. Disruption of carbon refractories in the test is sensitive to a number of variables, including alkali concentration, temperature, and the presence of water vapor. The procedure is suitable for guidance in product development and for relative comparisons in application work such as in blast furnace service.
