Electronics manufacturing requires a production environment with minimal pollutants to ensure that sensitive electronics are not harmed during the manufacturing process.

QV Test’s comprehensive cleanroom and controlled environment testing and certification services coupled with our technical expertise and regulatory knowledge will ensure your critical environments are in compliance with current standards and required specifications.

• Cleanroom Testing and Certification

  To show that a cleanroom is working satisfactorily, it is necessary to demonstrate that the following principles have been satisfied :

  • ‐ The air supplied to the cleanroom is of sufficient quantity to dilute or remove the contamination generated in the room.
  • ‐ The air supplied to the cleanroom is of a quality that will not add significantly to the contamination within the room.
  • ‐ The air within the cleanroom suite moves from clean to less‐clean areas to minimize the undesirable movement of contaminated air. Air should move in the correct direction through doorways and the construction fabrics of the room.
  • ‐ The air movement within the cleanroom should ensure that there are no areas within the room with high concentrations of contamination.

  QV Test offer service includes :
  Primary Tests are related to airborne particulate cleanliness class as required by ISO 14644. By performing these tests, the cleanroom will be correctly classified to the appropriate class level

  • - Airflow Velocity and Uniformity Tests
  • - Airflow Volume and Uniformity Tests
  • - Air Change Rate (ACH) Tests
  • - HEPA Filter Installation Leak Tests
  • - Airborne Particle Count Cleanliness Classification Tests
  • - Room Pressurization Test

  Secondary Tests are user optional and relate to particle, air movement, and ancillary systems within the cleanroom

  • - Airflow Smoke Pattern Tests
  • - Recovery Tests
  • - Lighting Level and Uniformity Tests
  • - Temperature and Humidity Uniformity Tests
• HVAC System: Air Handling Unit (AHU) Testing and Certification

  The heating, ventilation and air conditioning (HVAC) system that supports Cleanrooms must be verified. QV test offers the test includes :

  • - Airflow Velocity and Uniformity Tests
  • - HEPA Filter Installation Leak Tests
  • - Magnehelic Gauge Verification
• Environmental Control Unit Testing: Warehouse, Refrigerator/Freezer

  Temperature and humidity are important factors in the stability of pharmaceutical products. Temperature sensitive medi- cines/vaccines can degrade at higher temperature. Therefore, it is important to ensure that the temperature and humidity level in the storage areas could be maintained within the desired requirements.

  QV test offers service includes :

  - Temperature Mapping Studies / Temperature & Humidity Mapping Studies.

• Laminar Airflow Unit

  Laminar Cabinet is an area that is controlled the airflow pattern to be laminar, as it is highly likely that with Laminar airflow could lower the risk of contamination in orderly pattern. Conversely, turbulent air flow pattern could not be controlled, resulting to have high risk of contamination.

  

  The procedure of validation will be the same as individual cleanroom consist of :

  • - Airflow Velocity and Uniformity Tests
  • - HEPA Filter Installation Leak Tests
  • - Airborne Particle Count Cleanliness Classification Tests
  • - Differential Pressure and Magnehelic Gauge Reading
  • - Airflow Smoke Pattern Tests

  Normally, Laminar cabinet cleanliness class is “A” or class 100.
