MAIN FRAME

Comprises the integral framework structure, the assembly of the hydraulic jacket - piston, the base compression platen and the ball-seated upper compression platen.

HYDRAULIC SYSTEM

The hydraulic group is placed in the right part of the materials testing machine.

High pressure components are connected by flexible couplings.

STANDARD DELIVERY

• Testing frame MEHC-2000-MDW-10.
• Set of upper and lower compression platens.
• Safety shield.
• Waste sample slide board.
• Set of spacing blocks to adjust the vertical clearance for testing specimens of 10, 15 and 20 cm height.

SPACING BLOCKS

The spacing blocks (or distance pieces), are used to reduce vertical clearance between the contact surfaces of the ball seated upper platen and the base platen of the test frame when the height of the specimen is lower than 300 mm.

The standard spacing blocks have a diameter of 200 mm, according to EN 12390-4 standard, and their effective depth is 60 or 50 mm.

A chart with recommended spacing blocks to be used depending of the height of the specimen and/or testing devices that can be used with this range of machines is shown hereafter:

Lower Platen		60 mm thickness spacing block		50 mm thickness spacing block		Ball-seated Upper Platen

Without spacing blocks. Vertical clearance: 330 mm	60 mm spacing blocks Vertical clearance: 270 mm	60 + 50 mm spacing blocks Vertical clearance: 220 mm	60 + 2 X 50 mm spacing blocks Vertical clearance: 170 mm	60 + 3 X 50 mm spacing blocks Vertical clearance: 120 mm

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.
