Efficiency Uncertainty Estimation

The Efficiency Measurement’s Uncertainty is ±0.15%

The reported expanded uncertainty (U) was derived as the product of the combined standard uncertainty (u) and the coverage factor k = 2, corresponding to a confidence interval of approximately 95%. Measurement uncertainty was determined in accordance with JCGM Guide 100:2008, "Guide to the Expression of Uncertainty in Measurements". The estimate of the reported uncertainty pertains to values obtained during the measurements and does not account for possible long-term changes.
