U.S. TAG to ISO/TC 229,

  1. ISO
  2. ANSI ISO Activities
  3. ANSI-Administered U.S. TAGs
  4. U.S. TAG to ISO TC/229, Nanotechnologies


ANSI administers the U.S. Technical Advisory Group (TAG) for ISO/TC 229, Nanotechnologies. The scope of the U.S. TAG mirrors the scope of ISO/TC 229, as follows.

Standardization in the field of nanotechnologies that includes either or both of the following:

  • Understanding and control of matter and processes at the nanoscale, typically, but not exclusively, below 100 nanometers in one or more dimensions where the onset of size-dependent phenomena usually enables novel applications
  • Utilizing the properties of nanoscale materials that differ from the properties of individual atoms, molecules, and bulk matter to create improved materials, devices, and systems that exploit these new properties

Specific tasks include developing standards for: terminology and nomenclature; metrology and instrumentation, including specifications for reference materials; test methodologies; modelling and simulations; and science-based health, safety, and environmental practices.

At the ISO level, five Working Groups (WGs) operate under ISO/TC 229 Nanotechnologies:

  • WG1: Terminology and nomenclature (leadership assigned to Canada)
  • WG2: Measurement and characterization (leadership assigned to Japan)
  • WG3: Health, safety and environment (leadership assigned to the United States)
  • WG4: Materials specifications (leadership assigned to China)
  • WG5: Products and applications (leadership assigned to South Korea)

The ANSI-Accredited U.S. TAG to ISO/TC 229 mirrors the ISO Working Group structure. U.S. TAG WGs are advisory to the full U.S. TAG to ISO/TC 229. The full U.S. TAG retains final decision making authority on all U.S. positions and ballots.

Members & Officers

Membership on the ANSI-Accredited U.S. TAG is open to all materially affected U.S. parties interested in the coordination and development of international standards related to nanotechnology. The ANSI-Accredited U.S. TAG typically meets in person twice per year.
