Thanks for the reply.

Batch sizes may range between 50,000 and 1,500,000. A decision on batch change is made following a material or process change. Very often it is impossible to predict, at what time this might happen.

Our current sampling regime varies between 0.13% & 0.5% of product produced. On average approximately 5 products per 2500 produced are sampled & tested. Samples are collected during manufacture of the batch & checked in line.

Many thanks

Mike
