<p>ISO 18175:2004 describes procedures for evaluating the following performance characteristics of ultrasonic pulse-echo examination instruments:</p>
<p> horizontal limit and linearity;</p>
<p> vertical limit and linearity;</p>
<p> resolution-entry surface and far surface;</p>
<p> sensitivity and noise;</p>
<p> accuracy of calibrated gain controls.</p>
<p>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.</p>
