ASTM C914 – Standard Test Method for Bulk Density and Volume of Solid Refractories by Wax Immersion
Description:
Significance and Use
2.1 This test method may be used to quickly determine volume and bulk density of a refractory of any shape, provided it has sufficient structural integrity to permit handling. Thus it may be used on unfired or fired, strong or friable shapes.
2.2 Since the test may be performed quickly, it has found application as manufacturing in-process control as well as in characterizing finished refractory products. Also it may be used to examine specimens after other test or service exposure.
Scope
1.1 This test method covers the basic procedure for determining bulk density and volume of refractory shapes. This test is applicable to all refractory shapes or monoliths, burned or unburned, independent of composition or forming method, including materials that slake and hydrate. It is particularly suitable for determining bulk density and volume of complex shapes after forming, since results may be obtained in a matter of minutes.
1.2 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.2.1 Exception—The balance used in this standard is only available in SI units (Sections 3 – 6).
