STANDARDS  : EN 196-1, 459-2, 1015-11, 13454-2; ASTM C109, C348, C349; BS 3892-1, 4551-1
 
The PARSROS Automatic range of single testing chamber and double testing chamber compression and flexure testing machines have been designed for reliable and consistent testing of mortar samples. These compression and flexure testers are the results of continuous applications and research studies to upgrade the machines  with  the latest technologies and conform the current standards EN 196-1, 459-2, 1015-11, 13454- 2; ASTM C 109, C348, C349 and BS 3892-1, 4551-1 in terms of its technical properties taking into account client requirements by using suitable accessories. These machines also meet the requirements of CE norms for safety and health of the operator.
 
Compression and flexture jigs, distance pieces, and also removable transparent front-rear safety doors (should be factory installed) should be ordered separately.
 
The PARSROS automatic cement compression and flexure testing machines allow less experienced operators to perform the tests. Once the machine has been switched on and the specimen is positioned and centered by the help of centering apparatus. The only required operations are;

• Setting test parameters, including pace rate  (only required when the specimen type is changed.)

• Choosing the compression or flexure frame by using  the changeover valve.

• Pressing the START button on the control unit.
• The machine automatically starts the rapid approach; switches the test speed after 1% of the load capacity of the machine and stops once the specimen failure.

• Automatically saves the test parameters and test results.

The PARSROS automatic cement compression and flexure testing machines consist of very rigid two column single or double chamber frames, automatic hydraulic power pack with data acquisition and control system
 
Power Pack
Automatic Hydraulic Power Pack, dual stage, controlled by  is designed to supply the required oil to the load frames for loading. Very silent power pack can load the specimen between 50 N/sec to 2.4 kN/sec with an accuracy of ±5%. A Rapid approach pump is supplied as standard. Safety valve (maximum pressure valve) is used to avoid machine overloading.
 
Motor
The motor which drives the dual pump is an AC motor, 380 V, 50-60 Hz, 3 phase, 1 hp and 0.75 kW and it is controlled by Omron J7 motor inverter. The variation in the oil flow is executed with the variation of the rotation speed of the motor.
 
Distribution Block
A distribution block is used to control the oil flow direction supplied by the dual stage pump, the following parts are fitted to the distribution block;
a - Solenoid valve
b - Safety valve (maximum pressure valve)
c - Transducer
d - Low pressure gear pump
e - High pressure radial piston pump
 
Dual Stage Pump
The dual stage pump is formed by two groups;
  1-Low pressure gear pump
2-High pressure radial piston pump.
On the dual stage pump, a high delivery, low pressure gear pump is used for rapid approach, while a low delivery, high pressure radial piston pump is used for test execution. The Rapid approach facility shortens the time interval from piston start until the upper platen touches to the specimen. This excellent feature helps to save a lot of time when a large number of specimens are going to be tested.
 
Oil Tank
The tank includes enough oil to fill the mechanism which pushes the ram during the test. The level and oil temperature can be seen on the indicator fitted to the tank. It has 20 L capacity. Hydraulic motor oil, number 46, must be used.
 

Dimensions	360x380x900 mm
Weight (approx.)	80 kg
Power	750 W

TFT  Unit
TFT unit is designed to control the machine and processing of data from load-cells and pressure transducers which are fitted to the machine.
All the operations of TFT  are controlled from the front panel consisting of a 800x480 pixel 65535 color resistive touch screen display and function keys 2 analogue channels are provided for load-cells or pressure transducers.
 
TFT unit has easy to use menu options. It displays all menu option listings simultaneously, allowing the operator to access the required option in a seemless manner to activate the option or enter a numeric value to set the test parameters.
 
TheTFT  digital graphic display is able to draw real-time "Load vs. Time", or "Stress vs. Time" graphics.TFT unit offers many addition unique features. You can save more than 10000 test results in its internal memory. TFT  unit has support for various off-the-shelf USB printers, supporting both inkjet and laser printers. Thanks to its built-in internet protocol suite, every aspect of BC100 device can be controlled remotely from anywhere around the world.
