Abstract
The main objective of this SIM comparison was to evaluate the degree of equivalence between the participants in the calibration of mass standards. Six stainless steel weights were measured in each country's respective laboratory from October 2023 to May 2024.
The results reported were found to be consistent within the reported uncertainty. The largest normalized error calculated for this comparison was 0.85.
