If a sample fails to meet specifications, what is the retesting procedure?

The correct answer involves the necessity for retesting to be performed either at the same facility or at another facility, given that there is approval from the owner. This requirement underscores the importance of maintaining consistency in testing conditions, as variations in equipment, environment, or methodologies can lead to discrepancies in results. By ensuring that retesting occurs under regulated conditions, it helps to guarantee that the integrity of the data is preserved.

This procedure aligns with industry standards that emphasize accountability and traceability when dealing with materials that have not passed initial testing. Owner approval also adds an additional layer of oversight, ensuring that all parties are aware and agree to the retesting process, thus maintaining clear communication and responsibility among those involved.
