We are trying to figure out how our raw material testing plans compare to others in the industry and what the industry standard is considered to be.
We currently sample square root of n + 1 for all lots of incoming materials. We are considering implementing a reduced testing protocol that after 5 or 10 lots have been received and tested new lots only require 1 sample per lot to be pulled. What do others do?
For micro we currently test if the material has more than 10% water or if the vendor tests micro. What do others do for micro testing for products? Do you ever put this on reduced testing?
