Standard Practice for Measuring the Change in Length of Bolts Using the Ultrasonic Pulse-Echo Technique

Importancia y uso:

5.1 The techniques described provide for the measurement of change in length of a fastener. Such measurements are made from one end of the specimen without requiring access to the rear surface.

5.2 The Ultrasonic Pulse Echo technique is used to monitor changes in length of fasteners and as a tool for industrial quality control. Applications include fasteners used in turbines, petrochemical pressure vessels, aircraft, automotive manufacturing, general bolting within the nuclear industry, structural steel connections, and laboratory testing.
