Historical Standard: ASTM C769-98 Standard Test Method for Sonic Velocity in Manufactured Carbon and Graphite Materials for Use in Obtaining an Approximate Young's Modulus
SUPERSEDED (see Active link, below)
ASTM C769
1. Scope
1.1 This test method describes a procedure for measuring the sonic velocity in manufactured carbon and graphite materials having a grain size less than 0.80 mm ( 1/32 in.). The sonic velocity can be used to obtain an approximate value for Young's modulus.
1.2 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems 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 .
