Durability tests:
Durability tests:
On 15th of November 2018 Laboratory of Mechanical Testing and Metrology of TalTech carried out 2 different tests on 2 belt assemblies.
It is important to note that these tests did not follow any specific testing standards for climbing and rescue gear, as a single belt can never be used as safely as proper gear intended for climbing and rescue operations. The tests only indicate a very high durability.

Test #1:
Objective – pulling the closed belt loop apart until failure in the same position as it would be around the waist.
More speed was used on assembly nr2.
Every line drop indicates a larger tear and belts started giving up between the load of 4 and 5 kN – 0.41 ton-force and higher!
Load at break for 1st assembly at lower speed – 9.95kN / 1.01 in ton-force.
Load at break for 2nd assembly at higher speed – 7.05kN / 0.71 in ton-force.
7075 alu. buckles were not affected by these tests on visual inspection.

7075 alu. buckles were not affected by these tests on visual inspection.
Test #2:
Objective – pulling apart the side rope holes of the custom 7075 alu. buckle until failure.
1st buckle test – 22kN climbing carabiners in the top rope hole and rate of 10mm/min – Only buckle deformation and no breaking, as the gate of the 22kN carabiner broke at 20.08 kN! – 2.05 ton-force.
2nd buckle test – 26 kN climbing carabiners in the bottom rope hole and rate of 100mm/min – Bottom rope hole fractured in 2 places at 18.39 kN – 1.87 ton-force.

Random rappelling test:
Petzl Grigri 2 locked into buckle loops.
Not the correct way to use the Grigri and the belt is not a proper climbing/rescue harness!
