CONCLUSION
New testing high pressure facilities available at CTE since end 2006
At different temperature range for cylinders With hydrogen, at various temperature on components
First learning on high pressure components and cylinders
These equipments enable us to develop any specific test, with respect to standards or to any customer specification on high pressure cylinders or components
