Equipment
Experimental tests for teaching, research and services can be carried out on a variety of test devices from the micro to the macro level. A clamping field with test and support gantries allows compressive and tensile forces of up to 400 kN to be applied.
In addition to mechanical material and load-bearing capacity tests, building physics tests can also be carried out and materials can be artificially aged.
The main testing devices are listed below.
Test hall and test center
The 3m×6m clamping field enables a wide variety of test arrangements to be set up. In combination with the "Mocokit 400" load frame, experimental load tests of up to 400kN are possible.
MOCOKIT 400 clamping kit consisting of 3 m wide load and support gantries for carrying out bending tests up to 400 kN.
Pendulum impact tester with a double tire pendulum in accordance with DIN 12600 (50 kg) for pendulum impact tests to verify the impact resistance of fall-protection glazing in accordance with DIN 18008-4. The pendulum impact tester is mobile and can also be used on construction sites.
Impact body made of stainless steel in accordance with DIN 18008-5, Annex A, with a mass of 40 kg for verifying the impact resistance of glazing that can be walked on according to DIN 18008-5.
Canvas bag, filled with solid glass spheres Ø 3 mm in accordance with DIN EN 596:1995 with a total mass of 50 kg for carrying out impact and residual load tests on overhead glazing with fall-through protection or with limited access for cleaning and maintenance purposes in accordance with GS-Bau-18.
Test device as a double tire drop body with a mass of 50 kg for verifying the impact resistance of conditionally accessible overhead glazing in accordance with DIN 18008-6.
Test stand for ball drop test for the examination of safety glass according to DIN EN 356 and DIN 52338.
Compression tests of up to 3MN (3000kN) and bending tests with a load application of up to 200kN can be carried out on the compression test section.
Laboratory equipment
The universal testing machine (UPM) can be used for tensile, compression, shear force, deflection, peel, tear and bending tests with loads of up to 100kN. Deformations can be measured without contact using the two-axial video extensometer.
The video extensiometer enables non-contact optical detection of axial deformations in the universal testing machine.
Contact angle measurement is a suitable method for assessing the wettability of surfaces of parts to be joined. The size of the contact angle depends on the interactions between the part to be joined and the measuring liquid, whereby the contact angle increases with low interactions.
The finest structures and surfaces can be identified with the aid of transmitted or reflected light microscopy. Microscopy is used to evaluate the surfaces and pores of a wide variety of building materials.
Various sizes of Memmert drying ovens are available for sample preparation, conditioning and drying.
Various climate chambers for temperature/humidity storage. It is possible to measure the heat transfer through wall structures against the room climate. The temperature can be set from -80°C to +180°C and the humidity can be set to values between 10% and 98% relative humidity in a range from +10°C to +95°C. Fast heating and cooling speeds of up to 3 K/min allow rapid temperature changes.
Temperature storage and tests for solvent and detergent resistance can be carried out in a temperature cabinet within the temperature range of +30°C to +250°C. In addition to maintaining a constant temperature, it is also possible to program different temperature programs with several ramps and holding phases.
The spray mist chamber enables materials to be tested under the influence of a corrosive medium. Corrosion can lead to severe material changes and even failure of the material or joint, particularly in components with metallic parts.
Glass laboratory equipment
Laser-optical measuring device for determining the degree of toughening of thermally toughened flat glass (ESG/TVG).
Different materials, e.g. glass, can be fused together using the fusing oven. Various ceramic molds are available to shape the molten material.
The JETI Spectro-Radiometer is suitable for measuring the proportional wavelengths of light. The device is suitable for mobile use and is used in process control and for measuring spectral parameters of luminance and illuminance in rooms.
The real-time polarimeter from Ilis GmbH is suitable for measuring stresses in glass. The device is suitable for mobile use and is used in process control and research.
Laminating system for glass panes on a laboratory scale. 10 glass panes (1m x 0.5m) can be laminated in parallel. Special reusable silicone vacuum bags are used for lamination.
