The device for testing paper for punching “SP-35TM” is designed to determine the value of punching through paper and fibrous semi-finished products in accordance with GOST 13525.8-86. The principle of operation of the device is based on the creation of a smooth increasing overpressure in a chamber filled with glycerin formed by an elastic membrane until the moment at which the sample is clamped is destroyed.
SP-35TM
