What action should be taken if lumps are found in the residue?

If lumps are discovered in the residue, rerunning the test is essential for ensuring the accuracy of results. Lumps may indicate inconsistencies in the sample or the testing process itself, which can lead to unreliable data interpretation. By rerunning the test, you confirm whether the lumps are a recurring issue that might affect the overall findings, or if they were an isolated occurrence potentially caused by handling or environmental conditions during the initial testing.

This approach emphasizes the importance of maintaining quality control and assures that subsequent decisions based on test results are founded on accurate, repeatable data. It also addresses potential procedural errors and allows for corrective measures to be implemented if necessary, thereby enhancing the integrity of the testing process.
