Hi QAGB,
Thks again, i rather expected yr response. In other words, the customers are trusting yr data. So no claims. Unfortunately it also means that zero feedback to compare lab. performance.
Frankly, IMO a result of 10,000cfu/g could easily show 5000cfu/g on a repeated analysis of the same sample. This means that the 2 limits are within the error range of the measurement. It's slightly apples and oranges but for comparison, the typical micro.specs use M/m = 10:1
Well, the only systematic approach I know for predicting an APC level of prescribed safety margin below the maximum limit is a statistical one as per my preceding posts. I guess the choice is up to you.
Hi Charles,
Exactly. I'm pretty sure assumptions are made by the customers. We make certain assumptions too based on our suppliers until we have reason to investigate further.
We will eventually get this figured out (I'll stay optimistic), and I'll give some updates when I have them.
Thanks,
QAGB
