De Mattia
Fatigue
Check
Dynamic tester for the execution of fatigue tests in traction and bending in compliance with international standards
Standards the instrument complies with:
ASTM D813; ASTM D430-B; ISO 132; ISO 6943; JIS K_6260;
ASTM D813; ASTM D430-B; ISO 132; ISO 6943; JIS K_6260;
Overview
The instrument permits to perform dynamic tests for the determination of fatigue resistance of vulcanized rubbers under repeated deformations.
This instrument permits to perform:
• De Mattia Flex Cracking and Crack Growth test in Bending (ISO 132, ASTM D 430-B, DIN 53 522 1/2/3)
• Traction Fatigue tests in Traction (ISO 6943)
Instrument Regulation
According to the test method and the type of sample, the test cycle can be set by the user:
• The frequency can be set between 60 and 300 rpm
• The stroke can be set between 0 and 60 mm
• The distance of the grips can be set (up to 100 mm)
• The number of cycles before automatic stop can be set
• Up to 16 samples can be tested at the same time.
Construction
• Specimen holder with 16 positions
• Exclusive movement system with both sample holders moving in opposite directions to ensure low levels of noise and vibrations.
• CE labelling
Control device
The instrument is controlled via a Touch-Screen display that allows you to set:
• The number of cycles to be performed before the next interruption
• The Oscillation Frequency
Automatic Stop with grips opened
The new version of the instrument incorporates a feature that automatically brings the specimens to the fully open position when the test is stopped.
Fatigue and crack growth tests are very sensitive to test variables.
The new feature contributes substantially to the increase in the repeatability of the results.
Mould for De Mattia Flexure test
Mould for De Mattia dynamic tester according to ISO 132, ASTM D 430-method B, DIN 53 522 standards.
Piercing tool
The piercing tool allows to realize the standard notch to carry out crack-growth tests.
Development and production
The instrument is totally developed and produced in the plant of Gibitre Instruments in Italy.
All the mechanical parts are produced in the company workshop using modern CNC machines.
Components and sensors from well-known brands are selected in order to ensure the maximum reliability in the measures
Internal trained personnel takes care of all the production stages: assembly, start-up, calibration, packing, shipment and installation.
Safety devices
• Safety protection doors fitted with safety switch.
• Safety Push-button
• Digital Motor controller with torque overload control.
• CE labelling
Standard Calibration service for De Mattia Fatigue Check
The calibration is performed with reference to the requirements of ISO 132 standard.
The service includes:
• Ordinary maintenance of the instrument
• Calibration of the oscillation speed.
• Calibration of the dimension of the templates.
• Calibration of the temperature inside the environmental chamber at 4 temperatures (for flexometers with environmental Chamber)
• Issue and e-mail shipment of the Calibration Certificate with traceability to primary standards.
