Significance and Use
3.1 Alumina and alumina-silicate castable refractories are produced to yield property characteristics commensurate with different end-use properties. Volume stability, modulus of rupture, bulk density, and lime content have become useful measures to distinguish various alumina and alumina-silicate castable formulations for initial fitness for service. This classification is considered useful for purchase specifications and for quality control.
Scope
1.1 This classification covers alumina and alumina-silicate castable refractories that, when tempered with water, will develop structural strength by chemical action.
1.2 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.
1.3 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.
