In destructive testing, tests are carried out to the specimen’s failure. These tests are generally much easier to carry out, yield more information, and are easier to interpret than nondestructive testing. // Nondestructive testing (also called NDT, nondestructive evaluation, NDE, and nondestructive inspection, NDI) is testing that does not destroy the test object. ...
Testing of an object is often done in view of future use, which would make destructive testing pointless. However, it can be useful if the result gives information about similar specimens which are not tested.
In nondestructive testing, tests are carried out in such a way as to not disturb the specimen’s structural or surface integrity.
This type of testing is valuable because the specimen is not destroyed, however, these techniques generally require greater skill and the results are not always straightforward to interpret.
In general, destructivetesting yields much more valuable information on the condition of the specimen, but because the specimen is destroyed, the cost is generally greater.
