The Process for Undertaking Air Particle Counts


The Processfor Undertaking Air Particle Counts

APT Sound Testing undertakes airborne particulate testing to data centres and/or server rooms to confirm the level of air quality against the Cleanroom ISO 14644-1 standard for Cleanrooms which encompasses server rooms and Data Centres’.

The particulate tests are done using a UKAS calibrated air particle counter. APT Sound Testing aims to confirm that the Data Centre and each room within it meets the minimum ISO Class 8 for Data Centres and server rooms as per OEM best practice guidelines.



Taking the airborne particulate measurements

  1. Using a hand held or static air particle machine that has been properly calibrated collect  5 air sample per 10 square meters of room space -  in a 50m2 room a minimum of 10 tests should be taken and in 100m2 square meters 15 tests should be taken.
  2. The exact location of each particle test should be documented and if you are looking to trend the air quality in a certain room future tests should be taken at the same location each time.
  3. The air particle meter should be at an elevated height of one (1) meter above the floor surface.
  4. The air particle meter should remain static during the test.
  5. The air particle meter should be set to complete each test over a one (1) minute (sixty (60) second) period.
  6. During the test the machine will draw in one (1) cubic meter of air for analysis.
  7. The machine should be set to test particles at 0.5 microns for Class 7 & 8 and 0.3 micron for Class 5 & 6.
  8. The results of each test should be recorded. (I.e. test 1 = 3,200,000; test 2 = 2,500,012; test 3 = 832,000 etc) these results should be added together (6,532,011) and then divided by the number of tests (3) to get an average for the room (2,110.670) which in this example is a Class 8.
  9. Check against the ISO table below to identify the class achieved:



To achieve compliance with the relevant ISO standards, Cleanroom validation needs to be undertaken to ISO 14644-1:2015 - Classification of air cleanliness by particle concentration and ISO 14644-2:2015 - Monitoring to provide evidence of cleanroom performance related to air cleanliness by particle concentration.

APT Sound Testing provides a friendly and professional cleanroom validation service to the requirements of all current ISO standards and guidelines. We will issue you with test certificates containing up-to-date calibration certificates for all of the equipment used as well as recommendations for improvements that could be made to make the clean room more efficient in regards to its operation.

Clean Room Commissioning

Image
Clean Room Commissioning Cleanrooms are used in a wide variety of industries such as medical, Pharmaceutical and Biotech. Each Cleanroom play critical roles in maintaining contamination free production environments for critical processes. To ensure your cleanroom is working as designed it is essential that a well planned and executed cleanroom verification testing and certification and maintenance program is undertaken for operation and regulatory compliance. APT cleanroom testing offers clean room testing and clean room commissioning certification. Clean Room Environment It is essential that companies know if any airborne contaminants put products at risk.   It is also very important to understand what the contaminants are, and their origin.   Important environmental measurements, like airborne viable particle measurements, assist with keeping processes in control and with helping to find the root cause of unwanted events such as the ingress of filter pollutants
