Erichsen stamp is designed to determine the elasticity and strength of coatings with a bowl-shaped bend (hood coverage for the Erichsen) in compliance to ISO 1520.
The device is designed to determine the strength of coating during indentation of a spherical tip of the punch of 20 mm diameter to the coated test sample, which position is secured on the matrix with internal diameter of 27 mm.
This method is an effective method of determining of the quality of coating, it allows simultaneously to evaluate the strength, adhesion, and elasticity of the tested coating.
