Katsetatav viht on viht, mille massi mõõdetakse ja saadud mõõtetulemuse alusel lisatakse vihile või eemaldatakse vihist lisamass, et vihi mass oleks võrdne nimimassiga.
The test weight is a weight whose mass is measured and, based on the measurement result, additional mass is added to or removed from the weight so that the weight of the weight is equal to the nominal mass.
