Abstract

Weighing scale is a mass measuring instrument that plays an important role in ensuring the accuracy of the weighing process in laboratories and industries. To ensure the accuracy and traceability of measurement results, the scales need to be calibrated regularly according to international standards. This calibration activity aims to determine the conventional mass and uncertainty value of F1 class scales using E2 class scales as a reference standard, based on the direct comparison method according to OIML R-111:2004 guidelines. The calibration process is carried out using high-precision electronic scales with the STTS (Standard-Test Test-Standard) method, and takes into account environmental conditions according to ISO / IEC 17025:2017 standards. The calibration results show that all test scales are within the maximum permissible error (MPE) and have measurement uncertainties that are still in accordance with the tolerance requirements. The scales are declared suitable for use as class F1 measuring instruments because they meet the requirements according to OIML R-111:2004.
