1) There are different official standards for compression classes. The compression classes listed in this table correspond to the German GZG standard (Quality Mark Association for Medical Compression Stockings)

2) The allocation of the contact pressures and compression classes relating to the indications is not binding. They are suggestions which can be adjusted by the prescribing doctor based on the stage of the disease. The aim of the compression is to reduce the pain of patients and alleviate the disease. The compression class must also be measured against this target.
