The UTEST Automatic range of 2000 kN, 3000 kN, 4000 kN and 5000 kN capacity four column compression testing ma­chines have been designed for reliable and consistent testing of a wide range of specimens. These compression testers are the results of continuous research to upgrade the testing machines with the latest tech­nologies and conform to the latest standards EN 12390-3, 12390- 4, BS 1881 and ASTM C39 in terms of its technical properties taking into account client requirements. These also meet the requirements of CE norms for health and safety of the operator.

Testing machines are supplied with EN compression platens as standard. Machines also comply with the ASTM C39 standard when used together with suitable platens ( see page 128 ).

Tests can be performed by either on BC 100 Unit or on a computer with using free UTEST Software. The advantages of performing tests on  computer with using UTEST Software, such as reporting, graphical output, etc., can be seen at pages 155 and 156.

The UTEST Automatic range of 2000 kN, 3000 kN, 4000 kN and 5000 kN capacity four column compression testing machines allow inexperienced 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).
  • Pressing the START button on the control unit
  • The machine automatically starts the rapid approach, when the specimen touches the upper

platen the rapid approach is ended and starts loading at the pace rate that selected by user and stops once the specimen fails.

  • Automatically saves the test parameters and test results

All models are supplied in Class 1 starting from 50 kN as standard EN 12390-3, 12390-4, BS 1881 and ASTM C39.  UTEST range of Semi-Automatic and Automatic Machines can be upgraded with option UTC-0210 special calibration Class 1 starting from 1% of the full range. This exceptional performance enables the machines to be used for a considerable number of applications including:

  • Early age compression strength tests
  • Flexural tests by using proper accessories
  • Mortar (Cement) compression tests by using proper accessories
  • Core with low diameter compression tests

The compression machines consist of a heavy duty four column frame, automatic hydraulic power pack with data acquisition and control system BC 100.

UTC-5231 and UTC-5331 Testing Machine is supplied complete with;

  • Ø 205x90 mm, Ø 205x50 mm and Ø 205x30 mm distance pieces
  • UTC-4513 Upper Platen (with ball seating assembly) Ø300 mm, Lower Platen Ø300 mm.

UTC-4510, UTC-4511, UTC-4512 and UTC-4515 upper and lower platen sets can also be used with UTC-5231 and UTC-5331 testing machines.

UTC-5431 and UTC-5531 Compression Testing Machines are supplied complete with;

  • 2 pcs. Ø 205x90 mm, 2 pcs. Ø 205x50 mm and 2 pcs. Ø 205x30 mm distance pieces
  • UTC-4513 Upper Platen (with ball seating assembly) Ø300 mm, Lower Platen Ø300 mm.

UTC-4510, UTC-4511, UTC-4512 and UTC-4515 upper and lower platen sets can also be used with UTC-5431 and UTC-5531 Testing Machines.

Maximum horizontal clearance for placing sample is limited with the border of the platens. Sample must be placed such that its ends will not overflow from the ends of platens and it must be centred perfectly.

The suitable vertical clearance for specimen can be adjusted with distance pieces .

110 V, 50 Hz models are available upon request. The only difference is the input voltage.
