Workshop particle concentration

A room where materials undergo a purification process following specific procedures before entering a clean area.

The relative humidity in a production workshop.

The cleanliness level of a clean environment is distinguished based on the statistical quantity of suspended particles in the air per unit volume, where the particle size is greater than or equal to a specific size.

The measuring instrument for a given particle size responds to the equivalent spherical diameter of the particle being tested. Equivalent optical diameter is used for discrete particle counting and light scattering instruments.

The translation of the provided text is: "Workshops that require environmental control for regulating dust, powder, and microbial contamination. Their architectural structure, equipment, and usage have functions aimed at reducing the introduction, generation, and retention of contaminants in the area. Other relevant parameters such as temperature and pressure also need to be controlled."

The size range of solid and liquid particles suspended in the air for the purpose of classifying air cleanliness levels falls between 0.1 and 1000 micrometers (μm).
