Questions buyers ask
Do you carry out NDT yourselves or only witness it?
We witness and review NDT carried out by the manufacturer or its NDT contractor, and our inspectors can perform PMI and ultrasonic thickness checks. Where independent testing is needed, we arrange it through accredited laboratories.
Can you witness tests at a third-party laboratory?
Yes. We witness sampling, specimen marking and testing at the laboratory, so the results can be traced back to the heat or lot.
