In the validation of film-coating tablet process, I see my colleagues take samples to check weight uniformity. The validation would be carried out on three different speed, and at each speed, they take samples (20 tablets) at initial, 15 mins and 30 mins. Then they check weight of every tablets.
The thing makes me confused is that they also randomly check the total weight of 10 tablets at each timepoint. What is the meaning of this action?
Thank you for spending time reading my topic.
