What Is Class 10000 Cleanroom

Modern manufacturing processes and scientific research often require specific, very clean environmental conditions. A class 100 cleanroom to a class 10000 cleanroom refers to this kind of working environment. Class 100000 cleanrooms or ISO level 9 rooms also exist.  Smaller class numbers indicate the fewest particles floating in the air. 

What Is Class 10000 Cleanroom

1. What is class 10000 cleanroom - iso class 7 clean room?

Class 10 000 cleanroom has a maximum particle count of 10 000 particles per cubic foot in the air, corresponding to an ISO 7 cleanroom.

HEPA filter coverage required is 15-20% of the area. Moreover, the cleanroom class 10 000 required 60-90 air changes per hour with an average airflow velocity of 0.051-0.076 m/s

2. Class 10000 cleanroom standards - Iso class 7 cleanroom standards

Cleanroom classifications range from ISO 1 to ISO 9, with ISO 9 being the “dirtiest” and ISO 1 being the “cleanest”. The maximum allowable concentration of particles per cubic foot or meter of air is used to assign these classifications. Contamination levels in ISO 7/Class 10000 cleanrooms are measured by the concentration of particles in a cubic foot or meter of air. These levels are measured in microns and defined by the following standards:

ISO 14644-1 Standard for Maximum Number of Particles Permitted/m³ for ISO 7 Cleanroom

Particle size ≥0,1 µm ≥0,2 µm ≥0,3 µm ≥0,5µm ≥1µm ≥5 µm Maximum particles/m3 - - 1.020.000 352.000 83.200 2.930

US FED Standard 209E Maximum Number of Particles Permitted/ft³ for Class 10000 Cleanroom

Particle size ≥0,1 µm ≥0,2 µm ≥0,3 µm ≥0,5µm ≥5 µm Maximum particles/m3 350.000 75.000 30.000 10.000 70

3. Class 10000 cleanroom protection requirements

Class 10,000 cleanrooms require workers to wear fewer protective garments than class 1000, class 100 or class 10 cleanrooms. However, cleanroom clothing such as face masks, hair and beard covers, and lab coats or other frocks is still compulsory. Workers have to wear coveralls and gloves in some ISO 7 cleanrooms. Nonwoven fabrics are used in cleanroom clothing to prevent contamination from shedding material fibers.

Common ISO 7 cleanroom requirements include:

Pass box

HEPA fan filter units

Heat-welded vinyl or epoxy floors


Gowning atrium

Air conditioners

Entrance and exit sticky mats

Sealed lighting

Bunny suit, booties, and hood requirements

Stainless steel bench and hands-free sink
