ASTM C899 : 79(2022)

Standard Practice for Use of Metric Units of Measure for Reporting Properties of Refractory Materials

Standard Details

1.1 This practice presents the units to be employed for reporting the properties of refractories, such as density, crushing stress, modulus of rupture, tensile stress, thermal conductivity, and permeability.

1.2 For convenience, a table of conversion factors between inch-pound units and SI units is included.

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 StandardDetails, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
