WMT Maintenance Technik AG is committed to the success of your project. We help qualify and certify new designs for commercial use. In addition, we can ensure compliance with the following standards.
We test the following standards:
- ETSO 2C75 (aviation hose lines high pressure up to 210 bar)
- ETSO C53a (aviation hose lines medium pressure up to 107 bar)
- SAE AS2078 (hose assemblies, polytetrafluoroethylene (PTFE)
- MIL-DTL-25579/MIL-H-25579 (Hose assemblies, Polytetrafluoroethylene, High Temperature, Medium Pressure
- Fire protection test according to SAE AS1055
Do you have questions? Contact us, we are pleased to help you.
