EnviroMed was retained by Nufern to perform clean room verification of three clean rooms. The purpose of the assessment was to determine if the O.C. Clean Room, Draw Clean Room and the Chemical Lab Clean Room are meeting several requirements as dictated by the United States Federal Standard 209E. The clean rooms are located within the fiber optic production area of the facility.
Data was collected on various particle sizes with the use of a laser particle counter inside the clean room. A laser particle counter has the ability to obtain a count of particles ranging in size from 0.3 to 10 microns. Based on the clean room class and the size of the entrance plane, measurements were obtained from various locations within the room. Three samples were collected from each location. Upon completion of the measurements, total particle counts and calculations in accordance with Federal Standard 209E to determine efficiency of the room were printed out from the instrument.
