설명
A national metrology institute maintains primary reference standards — for example, NIST’s primary mass standard is a platinum-iridium kilogram prototype traceable to the 2019 SI redefinition via Kibble balance. Laboratories maintain secondary reference standards calibrated against primary ones: a 1 kg stainless steel reference weight with uncertainty of ±0.05 mg might serve as the reference for an entire factory’s weighing instruments.
