The accuracy of an analytical measurement is defined as the closeness of agreement between a test or measurement result and the true value. It usually requires calibration of the analytical method with a known standard. This is often done with standards of several concentrations to make a calibration or working curve.

The highest degree of confidence is achieved with Certified Reference Materials (CRMs), which are characterized by a metrologically valid procedure for one or more specified properties, accompanied by a certificate that provides the value of the specified property, its associated uncertainty, and a statement of metrological traceability, according to the definition stated in ISO Guide 30.
