mõõtetäpsus mõõtmise korratavustingimuste teatud kogumi korral, measurement precision under reproducibility conditions of measurement, sama mõõtesuuruse muutunud (muudetud) tingimustel sooritatud mõõtmistel saadud tulemuste lähedusaste, closeness of the agreement between the results of measurements of the same measurand carried out under changed conditions of measurement, closeness of agreement between the results of measurements of the same value of a quantity, when the individual measurements are made under different conditions of measurement: principle of measurement, method of measurement, observer, measuring instruments, reference standards, laboratory, under conditions of use of the instruments, different from those customarily used, after intervals of time relatively long compared with the duration of a single measurement, sama suuruse mõõtmisel saadud mõõtetulemuste lähedusaste, kui mõõtmine viidi läbi korratavustingimustel, limiting value for the difference between two independent results obtained in the normal and correct operation of the same method, for test material considered to be the same, under different test conditions, that is expected to be exceeded with a probability of 5 % due to random variation, kahe üksikkatse katsetulemuse erinevus, mis on saadud sama tavapärase ja nõuetekohase katsemeetodi toiminguga erinevatel katsetingimustel, eeldatavalt 5 % olulisuse tasemega juhusliku hajuvuse tõttu
