Obviously, but QA is based on statistic.
You need to destroy or damage the item tested If you want to check how a steel cable hold, You test it to the limit but after that you cannot use it anymore. So you get another one with the same specification. But if this one is defective for some reason, you would never know it until it fail.
You can perform QA on parts.
Or you trust the manufacturer of the part’s QA since they should know. After all they designed and built the thing.
