While the advantages of more energy-efficient lighting are clear, early replacements for traditional incandescent lamps didn’t meet customer expectations or manufacturer claims. NIST worked with industry partners to develop new measurement techniques so next-generation lighting could meet customer needs.

When a patient goes to a doctor’s office, hospital or clinic to get an MRI scan, he or she trusts that the medical imaging technologies are working properly. NIST and its partners developed tools to benchmark those tests, to support medical decisions and ensure patient trust.

The accuracy of flow meters measuring natural gas has enormous commercial importance. NIST is developing a new technique to calibrate large flows at high pressures, like natural gas flowing inside interstate pipelines, replacing today’s expensive, time-consuming and labor-intensive approach.
