TABLE OF CONTENTS In order that the terminology used in this section be understood, the flow chart in Figure 7-96 should be considered.
When NDT is specified, the following information must be provided:
The component description
The test method
The specification for the test
The specification for the test is most important. If there is no agreed upon definition regarding the type, size, and quantity of discontinuities, meaningful accept/reject determination will not be possible. The specification used should consider the component s fit ness for purpose. This means that the component should not have any discontinuities that would lead to its failure. This determination should be made by the designer of the specific component, who will use fracture mechanics to make this judgment. Evaluation of any indication should be made in consideration of the code or specification referenced in the purchase order or contract.
Unless a report is generated at the conclusion of an examination, there will be no record of it having been conducted. Examination repeatability is important, especially where the condition of a component is to be monitored periodically. Test reports should be developed that require certain information. A situation may arise where specific test reports are unavailable and the examiner may have to improvise.
Always ensure that as a minimum the following details are recorded clearly and concisely.
Date, Time, and Place of examination
Examiner s name and certification level
Component examined and its serial number if...
