In the last decade, sport climbing has become extremely popular, which has led to a greater demand for reliable climbing ropes with a longer lifespan. Usually, the wear of climbing ropes is assessed by visual inspection and subjective judgment of climbers, which is not always reliable and can pose a risk. With the desire to provide a more reliable assessment, we developed three non-destructive testing methods in our master's thesis. The methods include measuring the modulus of elasticity, the frequency of oscillation of the rope at the selected tension force and at the selected tension elongation. At the end, we broke the rope on the measured sections in order to obtain data on the real load capacity, which we used for comparison with non-destructive methods. The results of measuring the modulus of elasticity are the most similar to the results of destructive tests in terms of the shape of the graph. Due to the mechanical properties of the rope, the frequency measurements are much more complex than we initially imagined, and the results are suitable for this.
