De Mattia fatigue tester - Environmental Chamber

The instrument is built according to International Standards about fatigue, which describe test methods for the determination of the resistance of vulcanized rubbers under repeated deformations. This instrument permits to perform flex cracking/crack growth test and Tension fatigue test.

Temperature Control

The sample holding system is located in a thermal chamber Different thermal chambers are available:

- Heating Chamber: permits to set the temperature between room temperature and 200 °C

- Cooling Chamber: permits to set the temperature between -30 °C and room temperature

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

The exclusive movement system with both sample holders moving in opposite directions ensures extremely low levels of noise and vibrations.

The instrument is fitted with a motor controlled sample holder rotation system, which permits to inspect all the samples from the window of the thermal chamber without stopping the test.

Control device

The instrument is controlled using a touch screen display
