The Institute of Environmental Sciences and Technology (IEST) is a non-profit, technical society. Information on ISO 14644 and ISO 14698 Standards can be found through this organization.
Founded in 1953, the organization is headquartered in Arlington Heights, Illinois. Its members are internationally recognized in the fields of design, test, and evaluation; contamination control; product reliability; and aerospace.
The organization is the Secretariat of ISO/TC 209: cleanroom and associated controlled environments. This committee writes the ISO 14644 Standards. IEST is also a founding member of the ANSI-accrediated US TAG to ISO/TC 229 - Nanotechnologies.
The IEST also distributes to the public all ISO 14644 and ISO 14698 Standards.
IEST publishes and disseminates up-to-date, reliable, technical information within each of its divisions known as IEST Recommended Practices. These Recommended Practices provide procedures based on peer-approved applications. These documents are then formulated by IEST Working Groups. IEST has also revised such Federal Standards as FED-STD-209E, MIL-STD-781, MIL-STD-810, and MIL-STD-1246 (now IEST-STD-1246D).

IEST is currently in the works of developing Nanotechnology Recommended Practices. IEST Working Group 200 members have been meeting for many months to determine the structure of these documents.
Journal of the IEST
The online Journal of the IEST publishes peer-reviewed technical papers and free TechTalk articles related to the fields of contamination control; design, test, and evaluation; and product reliability. The online Journal provides never-before-available access to an entire decade of technical articles and peer-reviewed technical papers on simulation, testing, control, current research, and teaching of environmental sciences and technologies. The Journal of the IEST is the official publication of IEST, the Institute of Environmental Sciences and Technology, of archival quality with continuous publication since 1958. The April 2008 marks the 50th anniversary of the Journal of the IEST.
