23、eThis International Standard specifies minimum requirements for the contents of certificates for homogeneous gas mixtures in gas cylinders to be used as calibration gas mixtures. Pure gases, when used as calibration gas mixtures, are also covered by this International Standard. Gases and gas mixture
24、s produced for other purposes are not considered.The requirements in this International Standard deal with the metrological aspects of calibration gas mixtures. Other aspects, such as safety and legislative aspects, are not covered.Furthermore, it specifies additional information (optional data) rec
25、ommended for describing a homogeneous gas mixture, supplied under pressure in a cylinder or other container. It does not cover the field of safety-relevant data and related labelling.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and a
26、re indispensable for its application. For dated references, only the edition cited applies.
