What is ISO 6145-1 - Preparation of calibration gas mixtures using dynamic methods about?

ISO 6145-1 is the first part of the multi-series standard that is applicable to the preparation of calibration gas mixtures using dynamic methods. ISO 6145-1 gives a brief overview of each of the dynamic techniques which are described in detail in the subsequent parts of ISO 6145 . ISO 6145-1 provides basic information to support an informed choice for one or another method for the preparation of calibration gas mixtures. It also describes how these methods can be linked to national measurement standards to establish metrological traceability for the composition of the prepared gas mixtures.
