Standards

ASTM C39; AASHTO T22

UTC-4701.FPR, UTC-4701.FPR, UTC-4602.FPR, UTC-4702.FPR, UTC-4712, UTC-4722.FPR and UTC-4732.FPR models Automatic Compressıon Testıng Machines are manufactured for compression testing of acc. to ASTM & AASHTO standards. These machines also meet the requirements of CE norms with respect to the health and safety of the operator.

The machines allow inexperienced operators to perform the test. Once the machine has been switched on and the specimen is positioned and centered by the help of concentric centering line/s of lower bearing block (except Ø105 mm), 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.

The Machines consist of a welded steel frame (see table) and UTC-4830FPR automatic hydraulic power pack with U-Touch PRO Control Unit.

UTC-4680A or UTC-4682A Pedestals  that are made of steel to facilitate  the user’s  placement of specimens in the machines for compression test should be ordered separately.

Main Features

• Pace Rate control between 1 kN to 25 kN

• Accuracy Class A acc. to E74 and Class 1 acc. to ISO 7500-1 starting from with the 5% of the machine capacity (Special calibration option Class A starting from 1% of the full range with UTC-0210)

• Supplied with factory calibration certificate for load measurement
• Tests automatically with closed loop control
• The tests can be performed by controlling the machine either on U-Touch PRO control unit (UTC-4930.FPR) or on a computer with using free UTEST Software (USOFT-4830.FPR) which is provided free of charge with the machines.

• Load measurment with a pressure transducer
• Hydraulic pump with dual stage for rapid approach
• Welded steel walled frame with a single acting piston
• Piston return at the end of test automatically

U-Touch PRO Control Unit for Automatic Compression / Flexure Testing Machines

U-Touch PRO Control Unit UTC-4930.FPR is designed to perform automatically compression, flexure and splitting tensile strength tests of construction materials such as concrete, cement mortar, masonary units/blocks by controlling the Utest automatic compression / flexure testing machines.

All the operations of U-Touch PRO are controlled from the front panel touch screen display.

U-Touch PRO Control 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. Digital graphic display is able to draw real-time “Load vs. Time”, or “Stress vs. Time” graphics.

UTEST Software for Automatic Compression / Flexure Testing Machines

UTEST software USOFT-4830.FPR provides to perform automatically compression, flexure and splitting tensile strength tests of construction materials such as concrete, cement mortar, masonary units/blocks by controlling the Utest automatic compression / flexure testing machines

The advantages of performing tests on computer with using UTEST Software, such as reporting, graphical output, etc. can be seen in detail at the pages of UTEST Software for Automatic Compression / Flexure Testing Machines.

Optional Additional Frame

For compression and especially flexural testing, additionally second testing frame should be ordered separately.

In this case, the machines provide load control of two seperate testing frames with closed-loop P.I.D control with automatic test procedure by using selecting test channel and additional selector valve.

Safety Features

• Maximum pressure valves to avoid machine overloading
• Limit switch for piston stroke
• Emergency stop button
• Removable transparent front and rear safety doors
• Software controlled maximum load value
• The front safety doors have an automatic safety device to stop the machine if the door is opened during a test.
