Discover the latest best practices and risk considerations for maintaining the stability of deadweight primary standards in force calibration laboratories. This article by Henry Zumbrun (Morehouse Instrument Company), published in Cal Lab: The International Journal of Metrology, explains the hierarchy of force calibration standards, the unmatched long-term stability of deadweight machines, and the empirical evidence supporting calibration intervals of 20–30 years or more. It also outlines compliance strategies for ISO/IEC 17025, ILAC G24, and provides practical recommendations for laboratory maintenance and risk mitigation.
