For this question the answer is here. Assay is amount of analyte present in the given sample. If assay fails does not mean that it is impure. A sample with 90% w/w assay will still have 100% purity. Purity defines the impurities in it. The possibility to check would be if any weighing error otherwise perform Related substances test to check the number of impurities.
Then we can get clarity. In simple basis assay and purity are correlated. But if assay is less does not mean it is impure.
