Three characteristics of measurement science

The characteristics of the measurement process mainly include: maximum permissible error, measurement uncertainty, stability, repeatability and reproducibility.

Measurement is all operations aimed at determining the size of the measured object.

Three basic characteristics:

The purpose of (1) measurement is to determine the size of the measured value.

(2) The object of measurement is the "quantity" to be measured.

(3) The measurement process is both an experimental process and an operational process.
