Automatic Compression / Flexural Testing Machines

Application - Compression

Automatic range of 2000 kN and 3000 kN capacity 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 to 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 the safety and health of the operator.

Tests can be performed by either on BC 100 Unit or on a computer with using free Software. The advantages of performing tests on computer with using a Software, such as reporting, graphical output, etc., are also available.

The Automatic range of 2000 kN and 3000 kN capacity compression testing 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 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 10% of the full range as standard EN 12390-3, 12390-4, BS 1881 and ASTM C39.
Automatic Machines can be upgraded with option of 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 ( 2 or 3 days ) compression strength tests with UTC-0210
Flexural and splitting tests by using proper accessories
Mortar (Cement) compression tests by using proper accessories
Core testing with special accessories

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

Application - Flexural

Flexural Testing Frames are designed for minimum deflection at maximum load resulting in very high accuracy. The load frame is a welded steel fabrication carrying the ram fitted to the upper crosshead. All frames have a single acting down stroking ram with over travel switch protection to shut the machine down when maximum ram travel is reached. The return of the ram is done by dead weight or spring to get maximum accuracy on the load measurement. A load cell is used for load measurements on all frames.

Each model is designed to accept all accessories required for flexural, transverse or compression tests. Flexural Frames are available in 100 or 200kN capacity U type and 300kN C type open structure designed to allow easy and practical front loading of the specimen.
The very rigid C type design is ideal either for conventional flexural test or for more sophisticated tests such as deformability and ductility index.

The load frame provides the stability needed for accurate and repeatable test results over the years of operation.
All frames can be connected to any our compression machine as a second frame or can be used with any power pack as an independent Flexural Machine.
Flextural test assemblies should be ordered seperately.
