8. General Chapter <797> references both ISO 14644-1 and CAG-002-2006–section 2.09. Is there a conflict between these two guidance documents?

No, there is no conflict between these two guidance documents. General Chapter <797> references ISO 14644-1 to define the ISO classification of particulate matter in the primary and secondary engineering control. Additionally, the chapter specifies certification of engineering controls following procedures “such as those outlined in Certification Guide for Sterile Compounding Facilities (CAG-003-2006).” USP <797> further references CAG-002-2006 section 2.09 as sample procedures for placing Compounding Aseptic Isolators (CAI) and Compounding Aseptic Containment Isolators (CACI) outside of an ISO Class 7 buffer area. CAG-002-2006 section 2.09 is specifically referenced because it defines tests that prove whether a CAI or CACI can be placed outside of an ISO classified room. The test procedures in CAG-002-2006 are more robust than ISO 14644-1 because the tests increase the background particulate count. Section 2.09 increases background levels to prove that particulate contamination from the room is not dragged into the CAI or CACI when materials are transferred into or removed from the isolator. The procedures in ISO 14644-1 are not relevant to CAG-002-2006 section 2.09, and thus specific test procedures outlined in ISO 14644-1 are not referenced in these sections. Consequently, there is no conflict between CAG-002-2006 section 2.09 and ISO 14644-1.
