3 Principle
The thickness of the leather measured by the thickness gauge within a specified
load and within a specified time.
4 Device
4.1 Thickness gauge
4.1.1 Dial gauge, minimum scale 0.01 mm. It has a ± 0.02 mm accuracy within
the entire measuring range.
4.1.2 Test bench, a cylinder with horizontal surface, diameter (10.00 ± 0.05) mm,
height (3.0 ± 0.1) mm, installed on the surface of a coaxial round platform which
has a diameter of (50.0 ± 0.2) mm.
