Bibliography

Describes factors that may influence the composition of pure gases and homogeneous gas mixtures used for calibration purposes. It also applies to gases or gas mixtures that are within the "utilization period", and it pays special attention to storage of calibration gas cylinders; calibration gas withdrawal from cylinders and transfer of calibration gas from cylinders to the point of calibration.
