IEST publishes standards and Recommended Practices (RPs), sharing up-to-date, reliable technical information in these fields: contamination control; design, test and evaluation; product reliability, and nanotechnology facilities. IEST Working Groups create standardized procedures based upon peer-approved applications of environmental technology. 

Working Group members determine, through cooperative effort, what issues will be addressed and what procedures to include in each of these consensus documents, and what procedures will be included. 


IEST has revised U.S. Federal Standards such as FED-STD-209, MIL-STD-781, MIL-STD-810, and MIL-STD-1246 (now IEST-STD-1246E). The IEST Standards and Practices program administers WG-DTE043: MIL-STD-810G, the Working Group that provides expert support to this constantly evolving standard.
