1.1This practice covers the methods of calculating areas, volumes, and linear changes of irregularly shaped refractory specimens.

1.2Areas of irregular (both conventional and shaped) specimens are required for determining the creep of certain refractory products.

1.3Linear and volume changes or irregularly shaped refractories are required for determining reheat change.

1.4The values stated in SI units are to be regarded as the standard.

1.5This 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.
