IEST releases recommended practice on cleanroom residue

DEC. 11-ROLLING MEADOWS, Ill.–The Institute of Environmental Sciences and Technology (IEST), has released the latest addition to its Contamination Control Recommended Practice (RP) publications: IEST-RP-CC016.2: The Rate of Deposition of Nonvolatile Residue in Cleanrooms.

IEST Working Group WG-CC016, chaired by Gene Borson of Swales Aerospace, drafted this revision of an RP first published in 1992.

The recommended practice provides a uniform method and basis for defining the rates of deposition of nonvolatile residue (NVR) and other forms of molecular contamination on surfaces in cleanrooms.

This document was developed for use in defining the cleanroom environment. In addition, this recommended practice is intended to complement standards on allowable NVR and molecular contaminants on products, such as IEST-STD-CC1246D: Product Cleanliness Levels and Contamination Control Program.

IEST-RP-CC016.2 is available exclusively from the IEST, www.iest.org.
