STM9.1 and STM97.1 section 6.2.1 call for a sample size of 3 pair (6 total) as the minimum quantity for product qualification. How do we handle the situation where we won’t have 3 pair of the same footwear for PQ? The prime example would be employee purchased ESD shoes. Can it be as simple as noting on the PQ data report the test was done on a single pair?
