Dome Plasticity Fixture

The Dome Plasticity Fixture, also known as the Plastometer, serves as a sophisticated grain break apparatus designed specifically for measuring the set-in lasting characteristics of upper leather. This device adheres to the stringent design specifications outlined in BS 3144, Section 10, ensuring reliability and accuracy in its measurements.

The operational mechanism involves clamping a specimen at its rim using a specialized ring. By utilizing a knob, the operator exerts pressure to shape the leather into a spherical cap, extending its area to 115% of the original free disk. This altered form is then maintained for a predetermined duration, allowing for a precise evaluation of the leather’s plasticity. Once the measurement time elapses, the cap is released, enabling further analysis.
