Rheological tests of materials are time-consuming. The basic factors affecting the creep of materials are load and temperature. Experiments of modified wood showed that the duration of the research can be significantly shortened to determine their rheological properties.It should be used when there is a so-called linear creep (creep isochronous curves are linear) in the material.It was necessary to carry out studies on linearity of creep curves for at least three levels of stress. As a rheological model, the Zener model was used to describe creep. This model allowed to determine the value of results for other stress levels.
