Dissolution Performance Verification Testing (PVT)

The USP Performance Verification Test (PVT) is an integral part of the General Chapter <711> Dissolution and assesses proper dissolution apparatus performance. PVT is a holistic test and by using the reference standard material and the standard procedure, laboratories can compare results from their instrument with other laboratories worldwide. The PVT acceptance criteria for geometric mean (GM) and coefficient of variation (%CV) are a measure for the trueness and precision of the results within the context of ISO 5725-6.
