IEST accepted for membership on ANSI-accredited US TAG to ISO/TC 229 Nanotechnologies

ROLLING MEADOWS, IL–July 7, 2005–The Institute of Environmental Sciences and Technology (IEST) has been accepted as a voting member of the ANSI-accredited U.S. Technical Advisory Group (TAG) to ISO Technical Committee 229 Nanotechnologies.

The new Technical Committee was formed by the International Organization for Standardization (ISO) to address the nanotechnology disciplines. In its role as a member of US TAG to ISO/TC 229, IEST will represent the environmental sciences at the cutting edge of global standards development for these emerging technologies. The American National Standards Institute (ANSI) is the Administrator of the new TAG.

ISO/TC 229 Nanotechnologies will produce standards for classifications, terminology and nomenclature, basic metrology, calibration and certification, and environmental issues. Test methods will focus on physical, chemical, structural, and biological properties of materials or devices whose performance is critically dependent on one or more dimension less than 100 nm.

Dr. David S. Ensor, who will serve as IEST delegate to the US TAG to TC 229 Nanotechnologies, is a noted expert in the aerosol industry. He is Center Director and RTI Senior Fellow in Aerosol Science and Nanotechnology. In the aerosol field, he has over 90 peer-reviewed publications, more than 200 presentations, and five patents. He is a founding Editor-in-Chief of the journal, Aerosol Science and Technology.

Ensor is a technical editor for the Journal of the IEST, and a Fellow of IEST and ASHRAE. He has also served as IEST Technical Vice President (Contamination Control). Ensor recently served as convenor of the ISO/TC 209 working group that produced ISO 14644-7 Cleanrooms and associated controlled environments-Part 7: Separative devices (clean air hoods, gloveboxes, isolators and minienvironments).

The US TAG to ISO/TC 229 will hold its inaugural meeting July 19-20, 2005 in Gaithersburg, Maryland. At that time, the TAG is expected to review the title, scope, and structure of TC 229, develop strategies for obtaining a US leadership role in TC 229, and appoint a delegation to attend the first meeting of TC 229 this fall.

Long active in international standards writing, IEST is Secretariat of ISO/TC 209 Cleanrooms and associated controlled environments and Administrator of the ANSI-accredited US TAG to ISO/TC 209, which is responsible for establishing worldwide standards for cleanrooms. International standards produced by ISO/TC 209 established airborne particulate cleanliness classes for particle sizes ranging from 0.1 ?m to 0.5 ?m.

Founded in 1953, IEST is an international professional organization serving members and industries through education and the development of recommended practices and standards. Industries served are contamination control in electronics manufacturing and pharmaceutical processes; design, test and evaluation of commercial and military equipment; and product reliability issues associated with commercial and military systems.
