Pull-out tester 500

Hydraulic system for tear adherence tests on high resistance coating materials The Pull-Off is a direct method of proof consists of a semi-destructive extraction, used to estimate the tensile strength of materials. Recovery linked to the substrate, such as wall cladding (plaster or other). The test is prepared by pasting directly on the surface of the material to investigate, in an area specially designed with appropriate resins, a circular metal plate Ø 50 mm. Before the test is performed along the cutting edge of metal plate in order to release the evidence from the surrounding area. The cut should have a depth at least equal to the thickness of the coating. Maturation occurred at the resin by the application to the hard pressure of posting in the direction normal to the wall jack should be fitted with calibrated pressure gauge, which exercises opposing force on a support structure. • N.1 Single stage lever pump, working pressure 0-700bar, 1.4 cc / pumped, useful tank 0.5 liters (*); • No.1 NVT02B high precision digital pressure gauge 0-700bar with indication of min/max pressure peak, storage of selectable values ​​and measurement units (psi, MPa, kPa, bar, mbar), accuracy 0,20% F.S.
