Once you have your cleanroom constructed, the HVAC system balanced, and the room(s) precision cleaned, your cleanroom is now ready to be certified to the classification of cleanliness it was designed to.
At this point, you have two choices: 1) you can do it in-house, or 2) hire an experienced Certification Agency.
IN-HOUSE CERTIFICATION
After purchasing the needed documents that discuss in detail the required certification tests and testing procedures in conjunction with all of the calculations needed to certify your cleanroom, you now need to obtain the proper, recently calibrated equipment to do the various tests.
USING A 3RD PARTY CERTIFICATION AGENCY
While you may be up to the task of an in-house certification, there are advantages and cost savings associated with using an agency.
Obviously, there will be travel and per diem charges to come to your site. However, in the end you have a 3rd party opinion of the quality of your cleanroom facility along with a report with grid maps that you can utilize as a benchmark for establishing your on-going monitoring program.
