The IOW Block is a reference tool for setting up and checking conventional ultrasonic testing equipment. Also known as an A5 calibration block, it is designed for angle-beam profiling and beam-angle calibration, helping technicians understand and verify the performance of their ultrasonic probes. Side-drilled holes provide reference targets for assessing the ultrasonic beam at different positions. By comparing the responses from these targets, operators can evaluate beam characteristics and support repeatable equipment checks before undertaking inspections. Suitable for use in professional NDT workflows, the IOW Block supports inspection preparation, probe assessment and routine calibration activities. Selecting the appropriate block material and specification helps ensure suitability for the intended inspection procedure.
