Standard Guide for Evaluating Characteristics of Ultrasonic Search Units
Standard Guide for Evaluating Characteristics of Ultrasonic Search Units
Аннотация
This guide is intended to provide standardized procedures for evaluating ultrasonic search units. It is not intended to define performance and acceptance criteria, but rather to provide data from which such criteria may be established.
These procedures are intended to evaluate the characteristics of single-element piezoelectric search units.
Implementation may require more detailed procedural instructions in a format of the using facility.
