ASTM C1419-99a

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 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.

This test method is used to determine the sonic velocity and approximate Young’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.
