The ZIEGLER SAFT‑24 (Shear Adhesion Failure Temperature or Resistance to shear from a standard surface) is a shear tester designed for vertical shear tests (2° inclination to the vertical) of self-adhesive materials on test plates and their ability to withstand high temperatures. A shear force test with a constantly increasing temperature is performed in accordance with PTSC‑17. The samples are tested in a heating chamber for temperature control.
Supported test standards/methods
The shear force tester assesses the resistance of an adhesive to static load in the plane of the label material. Information is provided to interpret the failure mode, such as adhesive or cohesive failure. The test conditions are predefined. The SAFT tester complies with the specifications and test guidelines of various institutions (see "Supported test methods").
