component of measurement uncertainty resulting from the finite amount of detail in the definition of a measurand
NOTE 1 Definitional uncertainty is the practical minimum measurement uncertainty achievable in any measurement of a given measurand.
NOTE 2 Any change in the descriptive detail leads to another definitional uncertainty.
NOTE 3 In the ISO/IEC Guide 98-3:2008, D.3.4, and in IEC 60359, the concept 'definitional uncertainty' is termed “intrinsic uncertainty”.
