  • Clean room Classifications (ISO 8, ISO 7, ISO 6, ISO 5) | Mecart

    In theory, for a classified room (not just below a LAFW hood) to reach ISO 5 air cleanliness, you need to enter the cleanroom via an ISO 8 (ante-room), then go through an ISO 7, followed by an ISO 6 to finally get into the ISO 5. In reality, however, you can reach an ISO 5 cleanroom with 2 or 3 airlocks.

  • Understanding Cleanliness Classifications for Life Science

    FS 209Us FDA Application of ISO ClassificationsEU, PIC/S, and WhoRevised ISPE GradesThe classification of space by airborne particulate concentration began with Federal Standard 209 in 1963 and is the source for the classifications still used by the US Pharmacopeia and FDA (Table A): Other countries established standards that further complicated the terms and nomenclature affecting the design and cleanliness classification of global cleanroom facilities (Table B). As you can see, our current issue of aligning two standards is small by comparison to the historical alignment of diverse global standards. What’s more, the current underlying harmonized standard for space classification serves to align regulations to a great degree. To fully understand the similarities and differences between regulatory requirements, we must understand the harmonized space classification system on which they are based. ISO 14644-1:1999 (superseded):This standard defined classes of cleanliness by airborne particle count concentration following a decimal system. The classes are illustrated...
