To minimise particle contamination it is important to build separate environments, called cleanrooms that allow particle limits to be maintained at measurable and controllable levels. It is essential that cleanrooms are tested in-line with the relevant ISO standard to ensure they are working as designed.
A well designed cleanroom can achieve these great cleanliness levels by maximising laminar airflow and particle traps. Laminar airflow is air moving in one direction, which allows particles to be swept away from an area. Particle traps are areas where particles gather and escape laminar airflow. Careful cleanroom designs can minimise these areas to reduce particulate build up.
Hepa filters installed in the ceiling allow filtered air to pass down towards the floor. The floor tiles have small holes that allow the air to pass under the floor, where air-returns (air ducts) transport the air back to the ceiling filters. This filtration process can exchange the cleanroom’s entire volume of air more than thirty times per hour, resulting in the cleanest environment possible while minimising the movement of particles.
Clean room testing and certification guarantees that the facility has met the requirements for a statistically-valid maximum concentration of specified-size airborne particles.
Following our clean room testing and/or validation service, we present you with a clear, well-structured reportage that can be compiled, quality checked and issued to you while still on site, minimising the down time of your operations. We will also take time to explain the process and reportage to ensuring that you fully understand the testing process and your final results.
We will issue you with test certificates, as well as calibration certificates for all of the equipment used and we will also document any recommendations for improvements that could be made to make the clean room more efficient in regards to its operation.
