ISO class 6 clean room - class 1000 cleanroom definition

  • 20, 04, 2021

  

Cleanrooms are classified based on the number of particles found in the air. In this article, VCR will provide information about a type of cleanroom - Class 1000 cleanroom or ISO 6 clean room

1. What is class 1000 cleanroom - iso class 6 clean room?

   Class 1000 cleanroom has a maximum particle count of 1000 particles per cubic foot in air, corresponding to an ISO 6 cleanroom.

HEPA filter coverage required is 25-40% of the area. Moreover, the cleanroom class 1000 required 150-240 air changes per hour with an average airflow velocity of 0.127-0.203 m/s

2. Class 1000 cleanroom standard - Iso 6 clean room standard 

   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 6/Class 1000 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 6 Clean rooms
Particle size ≥0,1 µm ≥0,2 µm ≥0,3 µm ≥0,5µm ≥1µm ≥5 µm
Maximum particles/m3 1.000.000 237.000 102.000 35.200 8.320 293
  • US FED Standard 209E Maximum Number of Particles Permitted/ft³ for Class 1000 Cleanrooms
Particle size ≥0,1 µm ≥0,2 µm ≥0,3 µm ≥0,5µm ≥5 µm
Maximum particles/m3 35.500 7.500 3.000 1.000 7

3. Class 1000 cleanroom protective materials

   Cleanroom requirements vary widely based on industry standards and applications. We should consult a cleanroom specialist for assistance in choosing the design suited for your application.

Requirements for entering a Class 1000 clean room includes:

  • Clean room clothes
  • Shoe covers
  • Gloves

4. Requirements for class 1000 cleanroom protection

   To maintain the ISO 6 cleanliness classification, cleanrooms clothing should be used to prevent contamination from people and clothing. Required cleanroom clothing for class 1000 cleanrooms typically includes coveralls, hoods, gloves and shoe covers made from non-woven materials. 

In addition to clothing requirements, air showers and pass boxes are typically incorporated into the design of an ISO 6 cleanroom to prevent contaminants from entering the environment.

It is essential that you work with a cleanroom consultant to determine what precautions are required for your specific application. Common ISO 6 cleanroom contamination protection measures include:
