Invention is related to device for determination of resistance to pressing of cardboard or cardboard of chrome-ersatz.
The device comprises upper and lower pressing elements made in the form of two rectangular plates with identical rectangular holes in the centre of each plate; between which the examined one sample of cardboard or chromium-ersatz cardboard is clamped; wherein the upper pressing element has a pressing element with a hydraulic pressure generating means and a measuring means; Note here that said pushing element is composed of parallelepiped with its bottom made as half of cylinder. divided in half along the axis of the cylinder, the diameter of which is equal to the width of the parallelepiped. The design of the device for determining the resistance to pressing cardboard or cardboard with ersatz chrome provides for the examination of cardboard both in the longitudinal and in the transverse directions, that is, to obtain objective indicators of measurements of destructive pressure
