Significance and Use
This practice describes a method of fabrication of known discontinuities in a ceramic specimen. Such specimens are needed and used in nondestructive examination to demonstrate sensitivity and resolution and to assist in establishing proper examination parameters.
1.1 This practice covers a procedure for fabricating both green and sintered test samples of silicon carbide and silicon nitride containing inclusions. These samples can be used to determine the sensitivity and detection capability of a nondestructive examination (NDE) method.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 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.
