Beyond the component maintenance and production activitiesto design organization with wide testing opportunities
With 28 years of hose assembly and aggregate experience in the aviation sector, WMT Maintenance Technik AG has successfully established an alternative design organization for developing new designs and testing services according to 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
The approval includes following test equipment:
- proof pressure
- leakage (hydraulic leakage)
- room temperature (RT) burst pressure
- high temperature (ht) burst pressure
- hose conductivity
- impulse test (hydraulic impulse)
- fuel resistance
- pneumatic effusion
- pneumatic leakage
- pneumatic surge
- stress degradation (thermal shocks)
- corrosion
- over-tightening torque
- elongation and contraction
- volumetric expansion
- low temperature flexing (cold temp. flexing)
- vacuum (bending and vacuum)
- fire resistance
