Definition and Examples
Non-destructive examination is a form of examining a material or part without damaging the intended usefulness of the component. Unlike destructive examination, where the part is destroyed as a part of the examination, NDE methods are applied to find hidden indications of potential flaws. These are then compared to standards, established by sound engineering principles, to determine if the part can continue in service. NDE is often a routine part of design, manufacture and in-service testing performed to better establish and assess the reliability of the part in its design function.
In many cases, NDE is applied to establish the properties of a ‘new’ material. For example, new composite materials for aerospace are engineered products and as such, have indeterminate properties. NDE can be applied to these materials to aid in the assessment of their integrity and establish specifications to which subsequent new materials should be manufactured to assure application reliability.
