Cleanroom importance in laboratories.

Applied Tech Review | Wednesday, February 24, 2021

Cleanrooms are required to protect human health and industrial product assembly, with the primary goal of preventing the release of whatever particle is being handled within them.

FREMONT, CA: A Clean Room or cleanroom is a laboratory setting in which airborne particles are kept at very low concentrations. This space has been segregated, actively cleansed, and is free of a variety of particles and biological material, such as dust, airborne organisms, and vaporized particles. These rooms are required to protect human health and industrial product assembly, with the primary goal of preventing the release of whatever particle is being handled within them. Since multiple characteristics are regulated, they are highly specialized environments.

Since multiple characteristics are regulated, they are highly specialized environments.

The International Organization for Standardization (ISO) is a global federation of national standard bodies that was formed to provide standards for similar technologies in various countries. To assess the air quality and cleanliness of cleanrooms, standards and grading have been devised. The number of particles less than 0.5mm in one cubic foot of air is measured in Federal Standard 209 (A through D) of the United States, and this count is used to classify the cleanroom. The preliminary norm for the classification of clean zones and cleanrooms was Federal Standard 209E; however, in 1999, a new global standard replaced it (ISO 14644-1).

To assure the quality of the product being produced or the effectiveness of the procedure being conducted in the cleanroom, satisfactory cleanroom air quality is required. Some type of airborne sampling is required to evaluate whether the cleanroom meets the worldwide standard. Owing to the contributions of dynamic particulate levels, variability in sampling technique, and discrepancies or inconsistencies between the calibration and maintenance of sensors, there is frequent inconsistency in readings of airborne particles in cleanrooms. ISO categorization, on the other hand, provides a comprehensive framework for addressing discrepancies across different instruments.
