ASTM C455-07(2022)

ASTM C455-07(2022) is a standard published by ASTM International. Its full title is "Standard Classification of Chrome, Chrome-Magnesia, Magnesia-Chrome, and Magnesia Brick". This standard covers: SIGNIFICANCE AND USE 4.1 This classification categorizes the defined types of refractory brick, with the exception of chrome brick, into distinct classes based on a nominal and minimal value for magnesium oxide content. Chrome brick are treated as a separate class without reference to magnesium oxide content. Such classes have historically been generally useful in relating the defined types to specific industrial applications and in developing product or purchasing specifications. SCOPE 1.1 This classification categorizes machine-made refractory brick defined as chrome, chrome-magnesia, magnesia-chrome, and magnesia brick (see 3.1). It does not cover products made from electrically fused magnesium oxide or products made by fusion casting. Its purpose is to describe classes distinguished by obvious differences in magnesium oxide (MgO) content except for chrome brick. 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.
