With testing by ift Rosenheim, manufacturers can test their products in Europe and, for example, obtain the NFRC certification relevant for the US - without having to incur long transport routes and high shipping costs.
Performance characteristics such as sound and thermal insulation, lighting properties, fire resistance, burglar resistance and much more can be tested in the ift Rosenheim laboratories.

What tests are required?
ASTM 2190 prescribes the testing of insulating glass units in accordance with the ASTM 2188 and 2189 standards.
According to ASTM 2188, the frost/dew points of the insulating glass panes are determined. For this purpose, six glass panes are stored for a total of 15 weeks in a climatic chamber with high humidity and accelerated weathering.
The final frost/dew points must be -40°C or colder.

The resistance of insulating glass panes to fogging is tested in accordance with ASTM 2189. For this purpose, two panes (double insulating glass) or four panes (Triple insulating glass) are placed in a fogging box for seven days under UV radiation. If the glass panes show no visible fogging, the test is passed.
No visible fogging means the test has been passed.
What do manufacturers receive on completion of the test?
On completion of the MIG/VIG test in accordance with ASTM 2190 by the ift, the insulating glass manufacturers receive
