ISO 18175:2004

Non-destructive testing — Evaluating performance characteristics of ultrasonic pulse-echo testing systems without the use of electronic measurement instruments

ISO 18175:2004 describes procedures for evaluating the following performance characteristics of ultrasonic pulse-echo examination instruments:

horizontal limit and linearity;

vertical limit and linearity;

resolution-entry surface and far surface;

sensitivity and noise;

accuracy of calibrated gain controls.

ISO 18175:2004 may be used for the evaluation of a complete examination system, including transducer, instrument, interconnections, fixtures and connected alarm and auxiliary devices, primarily in cases where such a system is used repeatedly without change or substitution. This International Standard is not intended to be used as a substitute for calibration of a system to inspect any given material.
