ASTM 3370-24 Standard Practice for Matrix Array Ultrasonic Testing

ASTM E3370-24, titled “Standard Practice for Matrix Array Ultrasonic Testing of Composites, Sandwich Core Constructions, and Metals,” is a significant update to the existing standards for ultrasonic testing (UT). This standard practice provides detailed guidelines for the application of matrix array ultrasonic testing (MAUT) to detect and evaluate damage, discontinuities, and thickness variations in materials.
