Vacuum technology. Vacuum gauges. Evaluation of the uncertainties of results of calibrations by direct comparison with a reference gauge algolia-ignore BS EN ISO 5817 is1 Scope This International Standard gives guidelines for the determination and reporting of measurement uncertainties arising during vacuum gauge calibration by direct comparison with a reference gauge carried out in accordance with ISO TS 3567. This International Standard describes methods for uniform reporting of uncertainties in vacuum gauge certificates. Uncertainties reported in accordance with the guidelines given in this International Standard
