# Discovery and Information Sharing Event Regarding Direct Realization of Mass
**AGENCY:**
National Institute of Standards and Technology (NIST), Commerce.
**ACTION:**
Notice.
**SUMMARY:**
The National Institute of Standards and Technology (NIST) is providing a public opportunity to learn more about NIST efforts to develop a tabletop Kibble balance aimed at realizing mass [500 mg-20 g], with uncertainties of parts in 10 <sup>6</sup> , and traceable to the new quantum International System of Units (SI). The two-hour virtual meeting will take place October 19, 2022, 11 a.m.-1 p.m. eastern time.

**SUPPLEMENTARY INFORMATION:**
The National Institute of Standards and Technology (NIST) is providing a public opportunity to learn more about NIST efforts to develop a tabletop Kibble balance aimed at realizing mass [500 mg-20 g], with uncertainties of parts in 106, and traceable to the new quantum International System of Units (SI). A first-generation prototype, KIBB-g1 (patented by NIST), has proven gram-level masses can be directly realized via a tabletop-sized, low complexity, affordable system. Several government agencies are collaborating with NIST to develop a second- generation model (provisional patent submitted).
NIST is inviting industry leaders in mass metrology and precision balance manufacturing, as well as other interested parties, to attend a two-hour virtual meeting to learn more about the next generation tabletop Kibble balance and opportunities for potential collaboration with NIST to advance this technology.
