- The page cites JCGM 100:2008, EA-4/02 M:2022, and ILAC G8:09/2019, and says calculations run locally.
Field notes
The budget form lets users add components and enter evaluation, input, sensitivity coefficient, and degrees of freedom, then choose a coverage probability. A second form compares a measured value with lower and upper tolerance limits using the selected decision rule. The page lists JCGM 100:2008, EA-4/02 M:2022, and ILAC G8:09/2019 among its methods, and links to validation material and source code.
