Recommended calibration intervals for mass standards for Echelon III calibrations//" provides for good __initial__ calibration intervals. Where check weights (mass) are used to calibrate (or verify) the accuracy of weighing scales 2 or 3 times a year, these are typically placed on an extended calibration interval due to their seldom use and minimal wear (provided that they're not mishandled or damaged). | [[https://www.nist.gov/system/files/documents/2020/03/24/gmp-11-calibration-intervals-20190506.pdf|NIST GMP 11 – Good Measurement Practice for Assignment and Adjustment of Calibration Intervals for Laboratory Standards]], "//Table 3.
