Our laboratory is located in Ile-de-France and is internationally renowned for its expertise.

 Our mission is to carry out tests to qualify gas supply equipment and thus prevent incidents and accidents within the Air Liquide group and among our customers.

We test gas supply equipment, such as cylinders, valves and pressure reducers or hoses.

Our scope covers tests related to oxygen safety, the use of hydrogen, acetylene, and industrial and medical gases in general.

We carry out expert assessments to identify the origin of mechanical failures or failures of equipment used with oxygen.

 We estimate the residual life of methane steam reformer tubes.
