Bibliography
Describes the procedures to be followed in evaluating the uncertainty in the result of a measurement. It follows the principles set out in the document Guide to the expression of uncertainty in measurement, known as the GUM. It is intended for use by the practising measurement professional who seeks a practical guide to the application of the GUM's methodology to industrial measurement problems.

This Published Document sets out the procedures to be followed in evaluating the uncertainty in the result of a measurement. It follows the principles set out in the document Guide to the expression of uncertainty in measurement, known as the GUM (PD 6461-3). It is intended for use by the practising measurement professional who seeks a practical guide to the application of the GUM’s methodology to industrial measurement problems. This Published Document is applicable to situations where a formula or mathematical model is available for the required quantity in terms of input (or influence) quantities. It does not cover circumstances where reproducibility studies are required to provide a full statement of uncertainty.
Where this Published Document stops short of the rigorous approach advocated in the GUM, reference is made to the appropriate clause in the GUM for those requiring details of the full analysis.
Short examples illustrating the individual steps in the procedures are given in the body of the standard and a fuller example of the application of the procedures is given in Annex A.
