Logo TFI

The TFI carries out odour testing according to ISO 16000-28. This test procedure is mandatory for the award criteria of DE-UZ 128 and for the M1 label. The sensory parameters of perceived intensity, acceptance and hedonics are determined.
Our testing method (TFI) for odor evaluation also quickly provides a statement on the sensory.
This testing method is integrated in the GUT and Blue Angel labels (DE-UZ 128) for textile floor coverings.
