Standard Guide for Resonant Ultrasound Spectroscopy for Defect Detection in Both Metallic and Non-Metallic Parts
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This guide describes a procedure for detecting defects in metallic and non-metallic parts using the resonant ultrasound spectroscopy method. The procedure is intended for use with instruments capable of exciting and recording whole body resonant states within parts which exhibit acoustical or ultrasonic ringing. It is used to distinguish acceptable parts from those containing defects, such as cracks, voids, chips, density defects, tempering changes, and dimensional variations that are closely correlated with the elastic properties of the material.
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.
Significance and Use
The primary advantage of RUS is its ability of making numerous measurements in a single test. In addition, it can examine rough ground parts. It requires little sample preparation, no couplants, and generally will work with soiled items; however, it has no capability with soft materials. Soft metals, polymers, rubbers, and wood parts are not viable candidates for this technology.
