Automatic Compression Testing Machines for Blocks and Cylinders

ASTM C39, C140, C1314

UTC-4725.FPR and UTC-4735.FPR models Automatic Compressıon Testıng Machines have been designed for testing both blocks and cylinders specimens with the same frame according to ASTM standards. These machines also meet the requirements of CE norms with respect to the health and safety of the operator.

The frames of the machines have a rectangular and a circular bearing platen set (each consists of a lower and a shperically-seated upper platen). Depending on the type of specimen to be tested, the upper the bearing platens of the frames can be easily switched with each other by users with help of UTC-4528 and 4629.

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 lines of lower bearing platen. 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-4682A Pedestal  that is 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
