    Most metal parts testing is destructive. I.e., once you test the parts, they are destroyed and you can’t use them anymore. That’s why the trust I certificates is so important. They certify that metal from the same batch passed those tests. That’s why it’s a huge safety risk if the certs are fake, there’s no guarantee that the metal can meet the requirements, and no way to test without breaking the parts.
