Contamination control is the primary design goal of any cleanroom. Any potential source of contamination into the cleanroom must be thoroughly evaluated and minimized. Lighting fixtures should be subjected to contamination evaluation. Unfortunately, there are no established standards to prequalify fixtures for a particular cleanroom class. The National Sanitary Foundation (NSF) does provide listing and testing of materials used in food, pharmaceutical, medical or other FDA applications. Fixtures used in these applications should be required to carry the NSF listing mark. Manufacturers often advertise fixtures as being suitable for cleanroom use with no data or standard qualifications to substantiate their claims.
The basic cleanroom fixture types are teardrop, recessed, surface mount and integral ceiling grid. The selection of fixture type usually depends on the cleanroom classification.
