Greetings all.
I am currently studying EN 17141 at the suggestion of my auditor, and there is a table that I cannot understand.
In table B1 on page 26 the standard has four cleanroom categories: 1, 2, 3 and 4. However, I don't think this classification has anything to do with the ISO 14644-1 cleanroom categories. On the one hand because of the context, on the other hand because in the table B3 that follows they explicitly classify cleanrooms in categories 5, 6, 7 and 8 according to ISO 14644-1.
So if anyone has studied this standard, could you help me understand table B1?
Thank you in advance.
