In order to protect the environment authorities are increasingly imposing more stringent regulations on vehicle manufacturers. 

As a consequence, engine manufacturers, their suppliers and testing centres need to perform more rigorous emissions analysis.

Let Air Liquide support you and help with key expectations:

  • Compliance with legislation

  • Documentation and traceability

  • Reduced lead time

  • Reduced downtime between test cycles – better efficiency

  • Lowest total cost of ownership

Vehicle manufacturers are in a truly global environment and must meet the regulations set in Europe, the USA, Japan and China. Our calibration mixtures and pure gases manufactured with dual compliance to EPA and EURO norms that provide a single certificate for global compliance to Engine Testing legislation. In addition to this, companies and customers are aiming to increase efficiency and reduce errors in their testing. Changing a single cylinder or a pack on a central gas supply can dramatically impact the analytical performance of the equipment.

Air Liquide’s unique batch manufacturing and cylinder treatment technologies of mixtures alleviates this issue by enabling batches of mixtures to be produced.

Air Liquide today offers electronic certificates enabling customers to store and retrieve certificates easily

We also offer solutions that allow you perform automatic calibration of the analytical equipment by importing the certificate automatically. This is an efficient way to reduce human errors and enhance reliability of analytical values, as well as speeding up the analysis preparation.

By understanding your requirements we are able to offer a range of batch produced gases. 
This means:

 Reduced calibrations, Better reproducibility, Traceability, Efficiency, Confidence in compliance, which allows you to concentrate on testing and achieving homologation and engine approval.
