HVAC efficiency qualification roadmap, application guide and tips per ISO 14644-3: 2019 Cleanse place examination strategies and cleanse space classification according to ISO 14644-1: 2015
Cleanroom HVAC general performance qualification, recognized as “Cleanroom Validation,” is the most important established of checks to guarantee that the cleanroom is all set for its meant use and can meet up with and exceed user necessities talked about at a quite early stage in a cleanroom design .
Which checks must we carry out for cleanroom classification as component of our “cleanroom validation”?
Counting and classifying airborne particles in cleanrooms is the only way to classify cleanrooms. Classification is the process of assessing the diploma of cleanliness based on a specification for a clean home or clean up zone. ISO14644-1 is the only reference for assessing the degree of cleanliness (as ISO Class N) and no other assessments are required to classify cleanrooms. Table 1 must be your reference for “ISO Air High-quality Classes by Particle Concentration”.
The variety of sampling details was calculated in the 1999 version, but the newest version offers us a table for examining and defining no. Of sampling details in relation to the clean space area.
What other exams need to we do as element of the HVAC functionality qualification?
In get to perform a proper cleanroom effectiveness qualification, there are quite a few “supporting tests” talked about in ISO 14644-3: 2019 “Cleanroom examination methods” which had been formerly recognised as “optional tests” in the 2005 model of this ISO 14644-3 . All of these supporting checks are recorded in ISO 14644-3: 2015 Desk 2. All supporting assessments are outlined with Ideas (Part 4), Strategies (Appendix B), and Gear (Appendix C).
These tests are also referred to as “supporting / optional” checks. For correct cleanroom validation, you must run the exams most correct for your requirement. The cause for this is that the ISO 14644 collection is meant for all industries that use cleanrooms and managed environments. Electrostatic screening is important for the semiconductor and microelectronics industries, for instance, but not for car paint retailers with managed environments. Or the visualization of the air stream is a vital parameter for examining the unidirectional air move in sterile production traces in the pharmaceutical sector, whilst it is not significant for the thoroughly clean space for professional medical packaging with turbulent air.
