Adhesives in the classical building material testing are tested beside their solidification time also for their adhesive tensile strength and for their shear strength.
The setting times are often tested with Vicat devices according to EN 196-3, with a needle, or according to DIN EN 13279-2 with a dipping cone. The challenge here is the strong adhesion of the material to the penetrator. Effective, automatic cleaning is therefore of crucial importance for the test performance.
The tensile adhesion test is usually carried out using mobile manual devices, usually up to 20 kN. In case of high test volumes, testing machines with large frame dimensions are also used in order to be able to position large-format specimen carrier plates individually under the force axis.
Adhesive shear tests are carried out according to various standards using special jigs inside of our machines.
