Prüfung von viskoelastischen Stoffen

In a method of testing a sample of viscoelastic material held under pressure between two opposing, temperature-controlled dies, the sample is subjected to an oscillatory, rotary shearing force which has a predetermined amplitude and a frequency within the range 0.001 to 2 Hz, and a torque which is i...

Beschreibung
Zusammenfassung:	In a method of testing a sample of viscoelastic material held under pressure between two opposing, temperature-controlled dies, the sample is subjected to an oscillatory, rotary shearing force which has a predetermined amplitude and a frequency within the range 0.001 to 2 Hz, and a torque which is indicative of the response of the sample to the shearing force is measured, at least one measurement of said torque being made when the said predetermined amplitude is at least +/-10 DEG but not greater than +/-360 DEG . An apparatus for carrying out the method is also provided.
