3 Terms and Definitions
For the purpose of this standard, the following terms and definitions apply.
3.1
nominal value
specified quantity value
Note: In this standard, as for the quantity value evolved from nominal value, generally the specified tolerance is considered, and it is inspected through measurement.
3.2
median value
the value in the middle of several values obtained from test which are arranged in increasing (or decreasing) order in case the number of values is odd, or the mean value of two values in the middle of such values arranged as above in case the number of values is even
