Metrology: traceability and uncertainty

The VIM defines a number of metrology terms employed throughout this book:1

Calibration is the “operation that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties and, in a second step, uses this information to establish a relation for obtaining a measurement result from an indication” (VIM, 2.39).
