Description / Abstract:

This standard practice covers measurement procedures for evaluating certain characteristics of phased-array ultrasonic probes that are used with phased-array ultrasonic examination instrumentation.

This standard practice describes means for obtaining performance data that may be used to define the acoustic and electric responses of phased-array ultrasonic probes including contact (with or without a wedge) and immersion linear phased-array probes used for ultrasonic nondestructive testing with central frequencies ranging from 0.5 MHz to 10 MHz. Frequencies outside of this range may use the same methods but the testing equipment may vary.

When ultrasonic values dependent on material are specified in this document, they are based on carbon steel with an ultrasonic wave propagation speed of 5920 m/s (650 m/s) for longitudinal wave modes and 3255 m/s (630 m/s) for transverse or shear wave modes.

This document describes some of the characterization and verification procedures that can be carried out at the end stage of the manufacturing process of phased array probes. This document does not describe the methods or acceptance criteria used to verify the performance of the combined phased array ultrasonic instrument and probe system.

The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee
