Believe it alternatively no,[link widoczny dla zalogowanych], there namely an creation shrieked the UIAA which attempts a test standard for mountain climbing ropes.
One of the standards of such an institution for a rope to pass is that they must not be competent to break behind 5 fall tests with an impact of 12kN force. Various ropes are produced to be proficient to conform to certain descriptions.
The emulating are specifications ropes should be able to conform in order to be considered for worthy mountain climbing ropes. They are also guidelines for to what you should look for when you are choosing a mountain climbing rope.
Half rope and single rope test
The half mountain climbing rope test is where a particular object weighing fifty five kg is then dropped from a height of almost five meters. The rope fathom 2.5 m and should be able to not break and still hold the object.
The single mountain climbing rope test is where the same length of rope is accustomed with an object weighing eighty kilograms and is dropped from a height of almost five meters.
Pass the force of impact test
Determined in this test is the force value a rope could stand. Higher numbers show that extra force could be transferred to a climber when lower numbers show many better mountain climbing rope rendition. The befitting maximum force impact 8 kN for the mountain climbing half rope test and 12 kN for the unattached mountain climbing rope test.
Pass the elongation test
This is where the rope is tested as to how long it tin stretch. This is a rope's dynamic quality and is shown through percentages. The elongation that is considered the highest for single mountain climbing ropes is percentage of eight and maximum for half mountain climbing rope is percentage of ten.
Fall test
This is where an thing measuring 80 kg is tied to a 2.8 m rope and dropped from a five meter height. This is repeated until the mountain climbing rope breaks. A total of five falls is needed and the rope ought be able to survive such in order to pass.
