Leather is a natural product. According to the anatomy of the animal, there are differences in density of the fiber structure within the hide. Many testing procedures therefore produce varying results even within a single hide or from one hide to the next. On account of this, is it mandatory that quality assurance is conducted according to test methods and criteria developed by the leather industry or leather testing institutes.
The most important physical tests are carried out regularly in the in-house laboratory of Max Gimmel AG. Environmentally relevant chemical tests are carried out by specialist laboratories.
