Reference materials — Good practice in using reference materials
Third edition 2015-02-01
The aim of this Guide is to provide general recommendations on the use of RMs. These recommendations are exemplified by real-world examples, which to some degree also reflect the level of complexity associated with RMs. This level of detail is deemed to be useful for anyone who has a responsibility in the quality management in laboratories, such as drafters, reviewers, managers, and assessors of procedures, working instructions, standard operating procedures and the like. The main applications of reference materials are calibration, establishing traceability, method validation, assigning values to other materials, and quality control.
