IEST publishes contamination control document

Published: 15-Oct-2007

Controlling contamination spread in a cleanroom environment is the subject of a new document published by the Institute of Environmental Sciences and Technology (IEST).


IEST-RP-CC018.4: Cleanroom Housekeeping: Operating and Monitoring Procedures provides guidance for maintaining a cleanroom at the level for which it was designed and includes a new test procedure to establish frequency, monitor effectiveness, and determine appropriate levels of surface cleanliness.

The RP incorporates a new surface cleaning efficiency test method for nonviable particles. The test provides an automated measurement of surface cleanliness as it pertains to the efficiency of a wiping material to remove liquid contaminants from a surface. The document also has an expanded section on housekeeping equipment and supplies.

RP-CC018.4 will be included with registration for a Cleanroom Housekeeping tutorial on Wednesday, November 14, 2007, at the annual fall conference sponsored by IEST. This hands-on demonstration session will allow participants to view firsthand the methods outlined in the RP.
