DESCRIPTION
ISO 18175:2004
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.
