inspection of a homogeneous batch of measuring instruments based on the results of evaluation of a statistically appropriate number of specimens selected at random from an identified lot
Notes
Note 1 The conditions under which the respective instruments have been used (e.g. water quality for water meters) may be amongst the parameters determining the homogeneity of the batch.
Note 2 ISO 3534-2 gives the following definition: “4.1.6 sampling inspection - inspection of selected items in the group under consideration”
