What is the maximum particulate matter allowed in an ISO Class 7 cleanroom?

In an ISO Class 7 cleanroom, the maximum allowable particulate matter is defined according to specific standards for cleanliness levels in controlled environments. For ISO Class 7, the acceptable particle limit is no more than 10,000 particles per cubic meter for particles greater than 0.5 microns in size. This standard is significant because it ensures that the air quality is maintained within a range that minimizes contamination, thus protecting sensitive processes such as the preparation and handling of sterile pharmaceuticals and other critical materials.

The higher particle count allowed in ISO Class 7 compared to stricter classes (like Class 5) reflects the varying levels of environmental control that different cleanrooms require. This information is essential for IV technicians and professionals working in environments where sterility and cleanliness are paramount, as it guides them in the design, evaluation, and maintenance of cleanroom environments.

Understanding this limit helps technicians ensure compliance with regulations and best practices when working in cleanroom settings, significantly impacting the efficacy and safety of compounded sterile preparations.
