Concentration Values:

The concentration of each component in the gas mixture must be clearly stated.

Values should be given with appropriate units and significant figures.

Uncertainty of Measurements:

The certificate must include the uncertainty associated with each concentration value.

This uncertainty must be expressed with a confidence level, typically 95%.

Stability and Shelf Life:

Information on the stability of the gas mixture over time must be included.

The shelf life of the mixture and any conditions required for its storage should also be specified.


The certificate must provide evidence of traceability to national or international standards.

This ensures the gas mixture can be related back to a reference standard, providing confidence in its accuracy.

Date of Production and Expiry:

The production date of the gas mixture must be stated.

The expiry date, after which the gas mixture may no longer be reliable, must also be included.

Certification Statement:

A statement certifying that the gas mixture has been prepared and analyzed in accordance with relevant standards and procedures should be present.

Signature and Authorization:

The certificate must be signed by an authorized representative of the producer, indicating the information is accurate and reliable.
