Cleanroom Classification: Understanding the Differences in ISO Cleanroom Classifications

Cleanroom classification is a vital aspect of manufacturing and laboratory industries that require stringent control of environmental contaminants.

Properly classifying a cleanroom is essential for maintaining a controlled environment, avoiding contamination, and meeting regulatory requirements.

This article will explore what cleanroom classification is and the different types of ISO cleanroom classifications.

What Is A Cleanroom Classification?

A cleanroom is a controlled environment where the concentration of airborne particles is limited, and other environmental parameters, such as temperature, humidity, and air pressure, are maintained within specified limits.

A combination of air flow, filtration, and personnel gowning achieves the level of contamination control in a cleanroom.

Cleanroom classification refers to the level of cleanliness that a cleanroom can maintain based on the maximum allowable concentration of airborne particles.

The Different Types of Cleanroom Classification

Cleanroom classifications are based on the maximum allowable concentration of airborne particles, measured in microns per cubic meter of air.

The International Standards Organization (ISO) sets the global standards for cleanroom classifications.

ISO cleanroom classifications range from ISO 1 to ISO 9, with ISO 1 being the most stringent and ISO 9 being the least.

ISO Class 1: This is the highest level of cleanroom classification, with a maximum allowable concentration of airborne particles of fewer than ten particles per cubic meter of air, with a particle size of 0.1 microns or larger.

ISO Class 2: This classification has a maximum allowable concentration of airborne particles of fewer than 100 particles per cubic meter of air, with a particle size of 0.2 microns or larger.

ISO Class 3: This classification has a maximum allowable concentration of airborne particles of fewer than 1,000 particles per cubic meter of air, with a particle size of 0.5 microns or larger.

ISO Class 4: This classification has a maximum allowable concentration of airborne particles of fewer than 10,000 particles per cubic meter of air, with a particle size of 1 micron or larger.

ISO Class 5: This classification has a maximum allowable concentration of airborne particles of fewer than 100,000 particles per cubic meter of air, with a particle size of 5 microns or larger.

ISO Class 6: This classification has a maximum allowable concentration of airborne particles of fewer than 1,000,000 particles per cubic meter of air, with a particle size of 5 microns or larger.

ISO Class 7: This classification has a maximum allowable concentration of airborne particles of fewer than 10,000,000 per cubic meter of air, with a particle size of 5 microns or larger.

ISO Class 8: This classification has a maximum allowable concentration of airborne particles of fewer than 100,000,000 per cubic meter of air, with a particle size of 5 microns or larger.

ISO Class 9: This classification has a maximum allowable concentration of airborne particles of fewer than 1,000,000,000 particles per cubic meter of air, with a particle size of 5 microns or larger.
