Clean Room Certification Process

1. Determine the test items and parameter indicators

   In the confirmation of the clean room test method, clarify the items and parameter indicators that need to be tested, such as air cleanliness, temperature and humidity, pressure difference, etc. based on the clean room's characteristics and actual needs.

2. Environmental monitoring

   Use particle counters, temperature and humidity monitoring equipment, etc. to test the air quality, temperature, humidity, airflow, etc. to ensure meeting the required cleanliness level (such as ISO 7 or ISO 5).

3. Testing and recording

   Regularly monitor the concentration of particulates in the air, especially particles with a particle size of 0.5 microns and larger. Record the data in detail and compare with the standard requirements.

4. Compliance with standards

   The cleanroom must meet the cleanliness standards specified in iso 14644-1, including the number of particles at different levels, and the air change rate and airflow pattern must meet the specification requirements.

5. Third-party certification

   The certification body conducts assessment and inspection to obtain ISO 14644 certification or other industry standard certification, and issues a certificate of compliance.

6. Continuous compliance

   After certification, regular re-certification or supervision inspections are required to ensure continuous compliance with standards, along with necessary maintenance and corrections.
