Standard Practice for Ultrasonic Pulse-Echo Straight-Beam Contact Testing
This practice employs the use of normal-incident, or straight beam, longitudinal wave ultrasound for the detection and evaluation of discontinuities in materials requiring volumetric examination. Although not all requirements of this practice can be applied universally to all inspection situations and materials, it does provide the basis for establishing contractual criteria between suppliers and purchasers of materials for performing contact longitudinal wave pulse-echo examination and may be used as a guide for writing detailed procedures for particular applications.
