This document provides requirements and guidelines on the necessary quality assurance required
to produce calibration gas mixtures that are demonstrably stable and comparable. It shows that this
is achieved by demonstrating that the composition of the calibration gas mixture is metrologically
traceable to the SI.
This document shows that calibration gas mixtures can be prepared according to methods that have
measurements that are completely described in SI units. It describes procedures for verifying that the
composition of such gas mixtures is correct within the stated measurement uncertainty. Guidance is
given as to how to conduct the evaluation of uncertainty in these procedures.
This document also shows 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 gas mixtures with different characteristics, and this document explains these
differences and their implications.
Calibration gas mixtures, as prepared and certified for composition in accordance with this document,
are used for the calibration of equipment, the performance evaluation of methods, measurement
procedures and equipment.
