Accredited Mixtures

Provides confidence in the calibration decisions you make.

Specifies the general requirements for the competence to carry out tests and/or calibrations, including sampling. It is applicable to all organizations where testing and/or calibration forms part of inspection and product certification. ISO/IEC 17025 Accreditation is defined as a procedure by which an authoritative body gives formal recognition that a laboratory is competent to perform its work correctly and according to appropriate standards.


It’s the single most important metrology standard for test and measurement products. Nearly all national standards bodies and accreditation agencies around the world have adopted it. A growing number of companies require it and some industries have even incorporated it into sector-specific standards.


Air Liquide is committed to meet this international standard. Various manufacturing sites within the Air Liquide Group are now accredited as Calibration Laboratory.

  • The quality and competence of the calibration mixtures sold by Air Liquide is now independently verified through the accreditation process, which eliminates the needs for supplier auditing and provides a greater confidence in your supplier decisions.
  • Provide high confidence in the calibration decisions through validated uncertainty conformation. It directs Air Liquide calibration laboratories to:
    • analyze the uncertainty of each measurement
    • incorporate the uncertainty into the procedures
    • provide the uncertainties with the calibration certificate and results.
