L'ISO 3567:2011 spécifie les conditions physiques, techniques et métrologiques à remplir lors de l'étalonnage de manomètres à vide par comparaison directe avec un manomètre de référence. La conception d'un appareil pouvant effectuer des étalonnages de manomètres à vide de manière appropriée peut être déduite des conditions décrites.

ISO 27893:2011 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. ISO 27893:2011 describes methods for uniform reporting of uncertainties in vacuum gauge certificates. Uncertainties reported in accordance with the guidelines given in ISO 27893:2011 are transferable in the sense that the uncertainty evaluated for one result can be used as a component in the uncertainty evaluation of another measurement or calibration in which the first result is used. ISO 27893:2011 defines two measurement models that are sufficient to cover most practical cases. However, it is possible that the models given cannot be applied to newly developed vacuum gauges.
