Standards

• 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

Exceeding of the ASTM C-39 standard provisions (starts with the 10% of the machine capacity), the PRS-B4321, PRS-B4331, PRS-B6231 and PRS-B6331 are supplied in Class 1 starting from 50 kN. 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 welded frame, automatic hydraulic power pack with data acquisition and control system BC 100.
PRS-B4321and PRS-B4331Testing Machine is supplied complete with;

• Ø 205x90 mm, Ø 205x50 mm and Ø 205x30 mm distance pieces
• PRS-B4513 Upper Platen (with ball seating assembly) Ø300 mm, Lower Platen Ø300 mm.

PRS-B4510, PRS-B4511, PRS-B4512 and PRS-B4515 upper and lower platen sets can also be used with PRS-B4321 and PRS-B4331 testing machines.
PRS-B6321 and PRS-B6331 Compression Testing Machines are supplied complete with;

• Ø 165x90 mm, Ø 165x50 mm and 2 pcs. Ø 165x30 mm distance pieces
• PRS-B4511 Upper Platen (with ball seating assembly) Ø165 mm, Lower Platen Ø165 mm.

PRS-B4510, PRS-B4512 and PRS-B4515 upper and lower platen sets can also be used with PRS-B6321 and PRS-B6331 Compression Testing Machines.
Safety Features

• Maximum pressure valves to avoid machine overloading
• Piston travel limit switch
• Emergency stop button
• Front and rear transparent durable plexiglas guards
• Software controlled maximum load value

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.
