Standard Test Method for Sonic Velocity in Refractory Materials at Room Temperature and Its Use in Obtaining an Approximate Young's Modulus
Approximation of Young's Modulus is calculated through sonic velocity measurements in 3 directions. The velocity of sound waves is measured using a James V-meter.
SIGNIFICANCE AND USE
This test method is used to determine the sonic velocity and approximate Young's modulus of refractory shapes at room temperature. Since this test is nondestructive, specimens may be used for other tests as desired.
This test method is useful for research and development, engineering application and design, manufacturing quality and process control, and for developing purchasing specifications.
1.1 This test method describes a procedure for measuring the sonic velocity in refractory materials at room temperature. The sonic velocity can be used to obtain an approximate value for Young's modulus.
1.2 The sonic velocity may be measured through the length, thickness, and width of the specimen.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 This standard does not purport to address 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.
