Is it allowed to compress one batch on 2 different machine and why it is not allowed?
It may be not complete the machine equivalency parameter
the main question is that why u want to compress on 2 different machines?
Even if you have proven that both machines are equivalent, for traceability purposes it is not advisable. In case of deviation or complaint/recall, you would have an issue determining what part of the batch was produced on what machine. Why not create two batch numbers for batches produced on two machines, even when using the same batch of granulate?
