“NDE” stands for Non-Destructive Evaluation and “NDT” stands for Non-Destructive Testing. They sound similar and are often used interchangeably, but there are slight differences.
Non-Destructive Testing (NDT): This is a way of testing materials, like metals or concrete, without damaging or changing them.
Imagine you have a toy that might have a crack inside, but you don’t want to break it open to find out. NDT is like using a special flashlight that lets you see inside the toy without opening it.
It helps find flaws or problems in things like bridges, airplanes, and pipelines. Techniques used in NDT include using sound waves (ultrasound), magnetic fields, or x-rays.
Non-Destructive Evaluation (NDE): This is similar to NDT because it also involves examining materials without harming them.
However, NDE goes a step further by not only finding defects but also measuring how significant they are. It provides more detailed information.
For example, if NDT tells you there is a crack in a bridge, NDE would tell you if it’s a big problem that needs fixing right away or a small issue that can be checked again later.
NDT is about detecting defects,
NDE is about understanding more about those defects
