The Institute of Environmental Sciences and Technology (IEST) is a non-profit, technical society where professionals who impact controlled environments connect, gain knowledge, receive advice, and work together to create industry best practices. The organization uniquely serves environmental test engineers, qualification engineers, cleanroom professionals, those who work in product testing and evaluation, and others who work across a variety of industries, including: acoustics, aerospace, automotive, biotechnology/bioscience, climatics, cleanroom operations/design/equipment/certification, dynamics, filtration, food processing, HVAC design, medical devices, nanotechnology, pharmaceutical, semiconductors/microelectronics, and shock/vibration. Information on ISO 14644 and ISO 14698 standards can be found through this organization.

Founded in 1953, the organization is headquartered in Schaumburg, Illinois. Its members are internationally recognized in the fields of environmental tests; contamination control; product reliability; and aerospace.^[1]

International standards[edit]

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-accredited US TAG to ISO/TC 229 - Nanotechnologies.^[2] IEST has also revised such Federal Standards as FED-STD-209, MIL-STD-781, MIL-STD-810, and MIL-STD-1246 (now IEST-STD-1246E).^[3]

The IEST also distributes to the public all ISO 14644 and ISO 14698 standards.

Recommended practices[edit]

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-CC1246).^[4]
