Examine all units visually for container closure integrity, to the presence of any foreign make a difference while in the item together with other container closure defects. Observe results on analyst’s worksheet.
Info Comparisons. After the diagnostic testing has actually been completed, the data collected is often when compared to Individuals from equivalent tests performed throughout the original commissioning of the facility after which repeated in the course of revalidations, ordinarily yearly.
