Test on rope for elongation: the test shall be measured by clamp the rope piece on a suitable tensile testing machine under an initial load 2 % of the minimum breaking force.
Mark the distance above 250 mm as the gauge length L1.
Then load to 60 % of the minimum breaking force at the tensile speed not exceeding 50 mm/min, and measure the gauge length L2.
Then unload to the initial load and measure the gauge length L3.
