The following points are covered when performing a clean room particle measurement test:

  • Diameters of particles in clean room air
  • Pressure differences between clean rooms and corridors opening to these rooms
  • Relative humidity in clean room air
  • Temperature of clean room air
  • Amount of carbon dioxide present in clean room air
  • Amount of oxygen (O2) in clean room air
  • Amount of carbon monoxide in clean room air
  • Sound level in clean room
  • Possible air escape points and escaping air flow in ventilated areas

In the clean room tests, all these measurements are made and compared with the relevant standards.

Another point in clean room tests is the implementation of the HVAC system. The HVAC system is named after the initials of Heating, Ventilation and Air Conditioning. This system provides and controls the following parameters:

  • Temperature rating
  • Humidity
  • Number of weather changes per hour
  • Pressure differences
  • LAF air velocity (layered air currents)
  • Live and non-living particle numbers

Clean room use different HAVC system designs for different processes. According to the GMP Good Manufacturing Practice System standard, the basic requirements for the HVAC system are:

  • No cross contamination
  • Suitable conditions for the product must be provided
  • Employees must be trained
  • Clean room classification and process requirement must be ensured
  • Filtering of dust must be ensured
  • Solvent vapors must be destroyed
  • Staff must be protected

As a result of the tests conducted in the clean room tests inspection and testing organization edits a report. The results of this report showing the results of the evaluation are as follows:

  • Main schemes of clean rooms
  • Results of the measurement
  • Calibration dates of measuring instruments
  • What are the general deficiencies
  • Outputs in measurement tools
  • Current status of test room

Thanks to these clean room tests,

  • Service or product quality is guaranteed
  • Possible variations are minimized
  • The accuracy, precision and reproducibility of processes are proven
  • Efficiency of the organization increases
  • Ensures safe and well-controlled areas
  • Ensured that the employees are educated and knowledgeable

Clean room standards For the first time, the Federal Standard 209E standard was published. The ISO 14644 standard is then based on this standard. That's why the Federal Standard 209E no longer exists. The new standard is an upper form of it. In 2001, the Turkish Standards Institute has translated the Federal Standard 209E standard and has made the TS 11605 EN ISO 14644-1 standard in accordance with the conditions of our country.

The TÜRCERT certification body provides conformity assessment, certification and training services, and also provides testing and inspection services. Clean room testing is one of the services provided in this way. Please do not hesitate to contact the TÜRCERT certification body, its experienced managers and employees for more information about what to pay attention to when performing a clean room test.
