- It should have load measuring accuracy less than +0.5% of the measured value of Load in the Range from 2% -100% capacity
- It should have displacement measuring Accuracy less than +0.5% of the measured value of displacement
- It should have high speed Data acquisition and Statistical Analysis software
- It should have Online display of test data with real time plotting of Load-Time, Displacement-time, and Load-Displacement graphs, Stress-strain
- It should have Statistical analysis of the test results along with facility to export data to Excel
- It should have safety features like over travel limit for central cross head, over travel limit for ram and over loading of the system and overheating of oil should be provided as standard in the machine
- Hydraulic Pumping system should be based on Servo Hydraulic principle with servo/proportional valve to control motion of the cylinder/actuator
- It should be suitable for the supply of required flow and pressure for the movement of the actuator
- It should have an oil tank of adequate capacity, vane type pump powered by a three phase motor.
- All the electrical controls including the temperature controller should be fixed on one side of the tank.
- It should include all the accessories like pressure line filter, return line filter, oil level, relief valve, pressure gauge and air/water cooled heat exchanger
- Anti vibration mountings should be provided as standard along with the HPS.
