IQ of HVAC consist of a thorough verification of all of the set up components, to examine that e.g. valves, pipes, shutters, ventilation devices are appropriately set up as opposed with task format, and that they are thoroughly labelled. Of course a typical Test on documentation (drawings, format, part specification, listing of the suppliers, functioning manuals, and so forth.) is right here of paramount value. OQ of HVAC, which performs a important function in analyzing the caliber of air, normally foresee tests on air flowrate, HEPA filters integrity, the amount of air exchange / hour, particle and microbiological contamination. For these factors, comprehensive qualification of classified environments is often sub-contracted to ideal specialised assistance organizations. Nevertheless, the subsequent tests, which might be considered as agent of the general classification area classification position from the supposed rooms, might be executed, delivered that no less than an air particle counter and an incubator can be found.
