Abstract

Although nanonewton force measurements are commonplace in industry, no National Measurement Institute supports a link to the International System of Units (SI) below one newton. The National Institute of Standards and Technology has launched a five-year inter-laboratory project focusing on the development of an instrument and laboratory capable of realizing and measuring the SI unit of force below 5 micronewtons using the electrical units as the link to the SI. We will give a brief overview of this project, instrument performance objectives and designs, and initial trials with a prototype electrostatic force balance.
