Chapter 6, Problem 6.1PAE

Interpretation Introduction

Interpretation: The difference between non-destructive testing and other types of trace analysis has to be stated and an example of a situation in which non-destructive analysis might be important has to be written.

Concept introduction:

• Trace analysis is an analytical method used to detect, determine, quantify and study very minute (trace) materials.
• Non-destructive testing (NDT) is one of the trace analysis methods used to study the properties of a metal or a component or a system without causing any damage to it.
• NDT has a wide variety of usage because the sample does not lose its service ability after testing unlike other methods of analysis which are destructive in nature.
• NDT finds its applications in studying the differences in material properties such as ductility, tensile strength etc and in various manufacturing processes.
