What is Clean Room Classification: Understanding the Basics

Clean room classification refers to the process of categorizing clean rooms based on their level of cleanliness. A clean room is a controlled environment that has minimal pollutants such as dust, airborne microbes, and aerosol particles.
The International Organization for Standardization (ISO) sets standards for classifying clean rooms based on particle count per cubic meter of air. The lower the particle count, the higher the class rating.
There are different levels of clean room classifications, ranging from ISO Class 1 to ISO Class 9. Here's a breakdown:
  • ISO Class 1: This is the highest level of cleanliness achievable and allows no more than ten particles per cubic meter that measure 0.1 microns or larger.
  • ISO Class 2: Allows no more than one hundred particles per cubic meter measuring 0.1 microns or larger.
  • ISO Class 3: Allows no more than one thousand particles per cubic meter measuring 0.1 microns or larger.
  • ISO Class 4: Allows no more than ten thousand particles per cubic meter measuring 0.1 microns or larger.
  • ISO Classes 5 through to nine have increasingly higher particle counts allowed.
Clean rooms are used in various industries such as pharmaceuticals, biotech research labs, semiconductor manufacturing facilities and hospitals where maintaining sterile environments are crucial.
Adhering to strict standards ensures that products made in these environments remain free from contamination during production processes which could otherwise lead to product recalls costing millions in damages not forgetting human life too!
In conclusion, understanding cleanroom classification helps maintain safe working conditions while ensuring quality control measures meet industry standards keeping us all safe!
