Conducting the ISO 14644-3 Cleanroom Recovery Test with the MET ONE 3400+ This application note reviews the test method and provides guidance on selecting both the “Challenge” and the “Target Cleanliness Limit”. Attention is given to the requirement that the test concentration should not be so high that “residue contamination” becomes a risk.
Modern Trends in Non‐Viable Particle Monitoring during Aseptic Processing This paper describes changes and improvements to non‐viable particle monitoring (NVP), sometimes referred to as total particulate monitoring, which is a regulatory requirement during aseptic processing. Aseptic processing is becoming more automated and increasingly important to future products of the biopharmaceutical industry. In the same manner, NVP monitoring is also becoming more automated and increasingly important for contamination risk management during aseptic processing.
Changes to GMP Force Cleanroom Re-Classifications This paper explains the rules of ISO 14644-1:2015, which has substantial revisions impacting both the way the cleanrooms are classified and the performance requirements of the air particle counting instruments used to carry out the classification.
