ASTM C987-10(2023)

1.1 This test method covers a procedure for comparing the behavior of refractories in contact with vapors under conditions intended to simulate the environment within a glass-melting or other type of furnace when refractories are exposed to vapors from raw batch, molten glass, fuel, fuel contaminants, or other sources. This procedure is intended to accelerate service conditions for the purpose of determining in a relatively short time the interval resistance to fluxing, bloating, shrinkage, expansion, mineral conversion, disintegration, or other physical changes that may occur.

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.
