Measured quantity value minus a reference quantity value

  1. NOTE 1
    The concept of “measurement error” can be used both:
    1. (a)

      When there is a single reference quantity value to refer to, which occurs if a calibration is made by means of a measurement standard with a measured quantity value having a negligible measurement uncertainty or if a conventional quantity value is given, in which case the measurement error is known.

       
    2. (b)

      If a measurand is supposed to be represented by a unique true quantity value or a set of true quantity values of negligible range, in which case the measurement error is not known.

       
     
  2. NOTE 2

    Measurement error should not be confused with production error or mistake.

    (ISO Guide 99 2007, Definition 2.16)

     

Theory and Application

Let us start discussing the term “error” with the well-accepted definition of (ISO 99 2007), the International Vocabulary of Metrology (VIM), see definition.

In NOTE 1, we recognize...
