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

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

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

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

1.5 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 and health practices and determine the applicability of regulatory limitations prior to use.


3.1 Fireclay steel-teeming nozzles and sleeves are classified by volume reheat change. Bloating of some refractories results in irregular reheat dimensions, which are difficult to measure. This practice determines the volume without depending upon physical linear measurements.

3.2 Blast furnace checkers that have irregular cross-sections are classified by “creep properties.” This practice determines the average cross-sectional area without requiring area measurements.
