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

The maximum allowable particulate matter in ISO Class 7 cleanrooms is 352,000 particles per cubic meter of air. This classification is significant in environments where sterile compounding and other sensitive operations are conducted, as it establishes the limits for acceptable airborne contamination. The ISO classification system delineates different classes based on the number of particles of a specified size in a given volume of air, ensuring that environments maintain the necessary cleanliness standards to protect against contamination.

Understanding these standards is crucial for personnel involved in IV administration and compounding sterile products, as adherence to these limits helps ensure patient safety and the integrity of pharmaceuticals. Different ISO classes indicate varying levels of cleanliness, with ISO Class 7 being less stringent than higher classes, but still requiring vigilance to minimize the risk of contamination.
