ISO Classifications Definition
What are ISO classifications?
The allowed particle count in the air, defined in terms of cubic meters, is specified by ISO Classifications, particularly in the context of cleanrooms and controlled environments. They are outlined in the globally accepted ISO 14644-1 standard, used to uphold and certify the cleanliness and control of specific environments essential to the manufacturing, laboratory, and healthcare industries.
For particles measuring 0.5 mm and larger, the ISO 7 classification permits a maximum particle count of 352,000 per cubic meter. It is essential in sectors like pharmaceuticals and aerospace, where the quality and integrity of research or products must be ensured in a regulated environment with a highly constrained quantity of airborne particles. ISO 7 cleanrooms employ cutting-edge filtration techniques, regulate airflow patterns, and precisely supervise people and material flow to reduce particulate contamination.
With a limit of 3,520,000 particles per cubic meter for particles of 0.5 mm and above, ISO 8 categorization allows for a greater particle count than ISO 7. It provides a significantly clean environment suitable for different production and research operations that call for controlled contamination levels, even while it permits less strict control over particulates than ISO 7. Numerous industries, including various parts of manufacturing pharmaceuticals and medical devices, scientific research, and specific production areas in precision engineering, frequently use ISO 8 settings.
To guarantee that the required cleanliness and particle control standards are regularly maintained, ISO 7 and ISO 8 classifications call for rigorous management and ongoing environmental monitoring. It is accomplished by practicing precise protocols for air filtration, room pressurization, and person-to-person and material-to-person movement within and outside the cleanroom.
