Cleanroom Classifications
Understanding ISO Standards, and Maintaining Them in the Field
Cleanrooms are classified based on their level of airborne particulate contamination. The International Organization for Standardization (ISO) has established two primary sets of standards for cleanrooms: ISO 14698 for biocontamination control and ISO 14644 for airborne particulate control.
ISO 14644 is a comprehensive standard that outlines procedures for classifying, monitoring, testing, and operating cleanrooms. It defines the maximum allowable number of particles of a specific size within a given volume of air. Industry requirements and the specific purpose of the cleanroom determine the necessary ISO classification.
Cleanroom Cleaning FAQs
How often should cleanrooms be cleaned?
Cleanroom cleaning frequency depends on factors such as the specific industry, ISO classification, and the level of activity within the cleanroom. Generally speaking, regular cleaning is essential to maintain a controlled environment. A detailed cleaning schedule should be developed based on these factors.
What cleaning agents are safe to use in a cleanroom?
We only use cleaning agents specifically approved for use in cleanrooms. These agents are compatible with the materials used in the cleanroom and do not introduce additional contaminants.
What is the role of HEPA filters in cleanroom cleaning?
HEPA filters are essential for removing airborne particles from the cleanroom environment. They are typically used in HVAC systems and air filtration units. Regular maintenance and replacement of HEPA filters is crucial for maintaining a controlled environment.
