What is the procedure if there is a non-favorable comparison between QC and VT testing results?

The procedure to resolve a non-favorable comparison between Quality Control (QC) testing results and Verification Testing (VT) results is to utilize Resolution testing to determine which set of results to accept. This approach is important because it allows for an objective means of reconciling discrepancies between the two testing methods.

Resolution testing provides a systematic way to investigate the underlying reasons for the differing results. It may involve re-evaluating the materials, examining the testing procedures, or performing additional tests to establish which results accurately represent the condition being assessed. This method not only helps in gaining clarity on the results but ensures that decisions are made based on data that have undergone a thorough validation process.

Using the VT results for final decisions without further investigation could lead to decisions based on potentially flawed or unverified data. Similarly, conducting repeat testing immediately might not address the root cause of the initial discrepancy, and ignoring both results does not facilitate resolution or compliance with quality management protocols. Resolution testing, therefore, represents the most comprehensive and methodical approach to ensure integrity and reliability in testing outcomes.
