Question: How is NDT different from QA/QC?
Thanks for asking.
Please first understand the difference between QA & QC!
QC ensures that nothing produced out of specifications goes to the customer and QA means that all that is required to maintain the specifications of the final product (as desired by the customer) is being controlled in a measurable way.
NDT, being a test performed after the product is manufactured, is a part of QC hence it is different from QA but is a QC activity.
Hope this helps. （Author: DigitalOcean From: Quora）
