Pull-off test<\/h1><\/div>

The pull-off test is a minor destructive investigation technique that allows the measurement of the tensile strength or tear resistance of a material applied to a substrate, such as wall coverings (finishing mortars, plasters, seismic strengthening systems or other). This test is carried out by making a circular cut of 50 mm diameter on the surface of the material to be tested, to a depth at least equal to the thickness of the coating, using a circular drill bit or a grinder, to isolate the area subject to investigation. The tests is carried out by gluing a metal disk on the isolated surface, and then a traction force is applied perpendicularly to the surface using a jack equipped with a calibrated pressure gauge, until the detachment occurs on the contact plane between the structural layers, or on the substrate. <\/p>\n
