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

If lumps are found in the residue during a testing process, rerunning the test is crucial because the presence of lumps can indicate inconsistencies or contamination that may affect the accuracy of the results. Tests are designed to produce reliable and repeatable outcomes, and any anomaly, like lumps, could skew the data, leading to misinterpretation.

By rerunning the test, you ensure that the results reflect the true characteristics of the material being sampled, providing a clearer understanding of its properties. It’s a necessary step to uphold the validity of the testing process, which is vital in fields like earthwork where precision is important for safety and compliance.
