DYNAMIC PERFORMANCE
The testing equipment is similar to that used for testing climbing ropes, except that the rope is ca. 2 m long. At the ends it is tied in figure
eight knots and it is tested with five falls with a fall factor of 1. During the test, the rope must withstand all five falls. Type A ropes are
tested with a load of 100 kg. Type B ropes are tested with a load of 80 kg.

Testing of accessory cord
DIAMETER
Accessory cords are tested in a manner similar to testing of ropes, except that the pretensioning is less. According to EN 564, cords
should have diameters of 4, 5, 6, 7 and 8 mm. Smaller diameters (2 mm – avalanche cords, 3 mm – hammer cord and 9 mm – force
cord) do not comply with the norm.
