This document provides guidelines on the necessary quality assurance required to produce calibration gas mixtures that are demonstrably stable and comparable. It is shown that this is achieved by demonstrating that the composition of the calibration gas mixture is metrologically traceable to the SI. It is shown that calibration gas mixtures can be prepared according to methods that have measurements that are completely described in SI units. Procedures for verifying that the composition of such gas mixtures is correct within the stated measurement uncertainty are described. Guidance is given as to how to conduct the evaluation of uncertainty in these procedures. It is also shown how a calibration gas mixture with unknown composition can be calibrated by reference to traceable standard gas mixtures. This document covers the commonalities and differences of quality management schemes in use by producers of calibration gas mixtures, most notably those described in ISO/IEC 17025 and ISO 17034. These systems lead to calibration gas mixtures with different characteristics, and this standard explains which and their implications. Calibration gas mixtures, as prepared and certified for composition in accordance with this standard are used for the calibration of equipment, the performance evaluation of methods, measurement procedures and equipment.
