Why Engage A Third Party To Test A Cleanroom ? 
From an owner’s perspective,  the objective is to verify whether the actual performance of the cleanroom complies to the various pre-determined design parameters.
Owner ought to know with a confidence level beyond any reasonable doubt that the ROI from hiring a contractor to construct a multi-million cleanroom is realized as intended.
Why engage a third party firm, why owner not self-test the cleanroom ?
The clients of the owner demand factual and unbiased data that only an independent third party firm certified by NEBB can provide.
Such data is a pivotal part of the total quality assurance that products are manufactured within the audited cleanroom conditions.
Also, factual and unbiased data is possible only from qualified personnel certified by NEBB.
Data collection integrity is compromised by non-NEBB certified firm and personnel, and is exacerbated when the said firm outsources the issuance of the NEBB certificate to another vendor.
This is both a condescending move and self-defeating exercise by the non-NEBB certified firm taking on testing jobs beyond her limited professional capabilities.          
Any non-NEBB certified Dick, Tom and Harry  can easily invest in a particle counter and then claims she is capable of taking up testing jobs but none lacks the proper credentials to back it up.
From the owners’ perspective,  why risk investing multi-millions and then to potentially lose a huge contract (negative ROI) by letting non-NEBB certified firms without the proper credentials to audit and thereby compromising the actual performance of the cleanroom ?
