MEHC-AP-MC8W

Manufactured according to European Standard UNE-EN 772-1, EN 12.390/4 (hence UNE 83-304,DIN 51220, 51302, NF P 18-411, UNI 6686-1, 2,3, etc) and American Standards ASTM C39, AASTHO T22

Compact design, high pressure and embedded controller

ADVANTAGES

• Smaller dimensions
• Reduced space needed in the laboratory
• MC8W Control unit embedded configuration.
• Touch screen and fully operation software without separate computer.
• Mobile sleeve system to allow centering : axiality guaranteed.
• Four pre-stressed columns
• Superior plate mounted on a rotable ball and socket joint, with special design. Auto blocking system and lubricated by oil

TESTING FRAME: DESCRIPTION

Composed by:

• Lower frame: steel manufactured. Housing the piston-sleeve set. Base of the testing frame.
• Pre-stressed columns: for reaching the maximum stiffness to accomplish widely the EN 12390-4 standard, regarding undeformability of testing frames at full load.
• Upper crosshead, steel manufactured. Closing the test frame and increasing the stiffness of the testing frame.

Final Total deformation of the testing frame at full load is lower than 1mm

• Piston-sleeve set: the mobile sleeve system guarantees the perfect axial load. This set is mounted by means of bridles for a correct centering.
• Piston: rectified steel manufactured. Leak-proof by means of a high pressure, low friction, sealing joint.

• Compression plates (superior and inferior). Two steel rectified and tempered compression plates acting as compression elements.
  Contact surfaces according EN 12390-4:
  • Hardness higher than ≥ 550 HV30.
  • Flatness:
  • Rugosity: between 0,4 and 3,2 μmaccording to ISO/R 468
  The upper compression plate is mounted over a ball-and-socket joint, oil lubricated. Lower plate with diagonal and circular centering marks, for a correct sample positioning.
• Anti-projections screen: polycarbonate perimetral protection, with front door. High resistance to projections impact.
• An added safety protection is included in the door. An electrical switch stops the machine working if the door is open.
• Disposal tray. Mounted over the piston. Facilitates the retirement of the tests disposals.

CLOSED LOOP CONTROLLED HYDRAULIC SYSTEM

The hydraulic group is placed in the secondary frame which also houses the MC8W control module.

Water tight, noise and pollution prevention design, allowing placing the machine anywhere in the laboratory.

Motor-Pump

Composed by a radial piston high pressure pump, coupled directly to an electric motor.

Specifications:
• Rate flow: 1,5 litres/min
• Pump power: 1,5 kW

Tank

20 litres capacity. Mounted over elastic support to absorb vibrations of the motor-pump set Includding: • Fill acces with filter • Empty access • Visual oil level indicator

OPTIONAL EQUIPMENT

SPACING BLOCK

Steel manufactured, 50 mm thickness, needed for those tests over samples with height lower than 300 mm.

These spacing blocks are placed over the load piston, under the lower compression plate.

Designed with a self centering shape, with handles for a comfortable movement.

RECTANGULAR COMPRESSION PLATES 450 X 300 mm

For prismatic samples testing, aside the standardized cylindrical ones (concrete block, bricks, etc).

These compression plates are steel rectified and tempered manufactured. Suface hardness higher than 550 HV30.

Lower plate with diagonal and circular centering marks, for a correct sample positioning.

The upper compression plate is mounted over a ball-andsocket joint.

NOTE: these plates must be mounted in our factory replacing the circular supplied as standard delivery.

LOWER COMPRESSION PLATE ELEVATION DEVICE

To facilitate the retirement of the rectangular compression plate of 450 x 300 mm (for example for introducing spacing blocks), its heavy weight complicates the handling. This manual operated system, placed in the back side of the machine, allows the easy and fast elevation of the lower compression plate.

ELECTRONIC CONTROL UNIT MC8W

Microprocessed 32 bits electronic module with floatting comma calculating unit, working at 800 Mhz clock frequency.

Developed for autonomous working.

Designed for test data acquisition and close loop control.

Languages: English, Spanish, French and Portuguese. Reports could be generated in any other language as well.

Network connectivity: Possibility of being remote PC controlled for test configuration and data reading by means of Ethernet 10/100Mbps (RJ45) or Wi-Fi.

Touch screen LCD display:

19” with more than 1280x1024 resolution. User friendly interface with user High resolution graphs Virtual complete keyboard showed in the screen only when data introduction is demanded.

Data Storage:In a standard compression test, around 7200 points are generated. The user can save all these data.

• Up to 1000 complete tests data could be stored in the internal memory
• More than 5 million test results could be stored in the internal memory

Peripheral connections:3 USB ports placed on the front and on the rear part of the machine.
Some USB adapters must be configured by IBERTEST

AVAILABLE ACCESORIES

Flexural test,using simple or double upper roller, over prismatic concrete samples according to EN 12.394 part 5, ASTM C78 and C293.

Tensile Splitting tests over prismatic concrete cubes(100mm&150mm) according to EN-12390-6 and block pavers according to EN 4338.

Tensile Splitting tests on concrete Cylinders according to EN-12390-6 and ASTM C 496.

Young and Poisson modulus determination, using appropriate testing devices, accessories and software, according to European or American Standards (to be specified)

SOFTWARE, FOR STATIC TEST UNDER WINDOWS, WINTEST.HOR

The control module is fully managed by the WINTEST32 software.

Allows testing conguration and execution as well as a later data management.

The software has been specially adapted to this machine, including double working possibility:

• Simple mode: for productivity increasing enabling quick and repetitive tests process. Configuration steps have been reduced to the minimum. Especially useful for test over same material samples.

• Full mode: the user could use all the power of WINTEST software.
Easy change from working modes
When the module is working on remote mode, the controller PC is capable of carrying out the same actions as if the user were in front of the module.

See particular technical specifications in WINTEST Brochure.

TELEDIAGNOSIS SYSTEM

Only for pc controlled IBERTEST machines

Allows a direct links between the machine (any place with pone connection) and the Technical service of IBERTEST.

With this link the Post sale service of IBERTEST could easily diagnose and, most of times correct, the failures detected in the software without the need of a technical displacement.
